I have always said I think he was correct.
The world cup has nothing to do with development and the qualifies are over 3 games not 1
If I was him I would of approached it the same way.
Unfortunately he had some bad luck.

Neill: I Didn't Even Do Team Talk

SOCCEROOS skipper has denied leading a player revolt against World Cup coach Pim Verbeek - and claimed he didn't even make a team talk before the crushing defeat against Germany

Broadcaster Les Murray has claimed Neill mutinied against Verbeek and moments before the match began, he wiped the whiteboard cleanand told players to forget the Dutchman's "bullshit" tactics.

FFA CEO Ben Buckley last night defended Neill's record as Australian captain and insisted no-one with the Socceroos could recall the incident.

But today Lucas Neill finally spoke out and defended himself against the accusations, contained in Murray's new book, The World Game.

"I'm on holiday and absolutely shocked by this," he told Fox Sports News by phone from the US this morning. "I'm a little bit angry.

"It's clearly not true from my point of view and easy to quantify. I'd like to know how it came about? If it's just a way to sell a book then so be it - I've seen it done before.

"But I don't want it to be me, and my name, and my reputation and all the hard work that we try to do for football, to be probably looking bad in public opinion at the moment which is not what I want.

"Because it was a year ago, you wrack your brains trying to remember what happened but clearly, what's been read to me - because I haven't even read it myself - is just stunning.

"I'm trying to get hold of Mark Schwarzer now because we were talking before the game about how we were going to approach it.

"And in the end Schwarzie started talking in the changing room before the game and before we knew it, it was time to go out..

"I didn't actually get to give my captain's speech, which the boys will tell you is something I like to do before the game.

"So on that particular night, I didn't even get to make a speech."

He denied asking Verbeek to leave the dressing room so he could address the players or scrubbing the whiteboard.

"I can't recall anything like that," he said. "I can remember a whiteboard being in there but nothing like that.

"We're a team and we shake hands as a group of 40, and that includes backroom staff, medical staff, no-one gets the opportunity to go out early.

"I as a captain, I certainly wouldn't tell everyone to go out the room on one of the greatest nights in any player's life. The subs go out a little bit early but that's right at the death.

"Players will be high-fiving each other and geeing each other up. We have all our meetings before the game. Anything that gets done, gets done on a computer.

"We sit there as a group of 23 players and go over the tactics and when we go into the changing rooms, it's just about putting the last reminders up and refreshing each other's memory.

"But usually that doesn't get done on a little whiteboard, that gets done in a little speech."

Neill also paid tribute to former coach Verbeek and defended his legacy.

"Pim got judged on 16 games in that era and everyone only remembers that game," he said. "We got beat 4-0 and it was tragic, it was tragic for the team, tragic for Australia.

"It was disappointing in hindsight. Could we have done something different? Of course, we could have, but that's hindsight. Everyone wants to have hindsight.

"From the point of view of going out on the pitch, the response to losing 4-0 was amazing.

"I firmly played my part as did many of the others in picking the team up and getting it to go again and trying to qualify from a position we probably didn't deserve to qualify from.

"Pim won us so many great games in tough places to win games. He got us to the World Cup with time to spare.

"That's credit to a man who, okay, didn't go down well in everyone's books, but as a captain I'm not going to undermine that guy. He's my manager. He's my boss.

"Whatever he says, I'm going to get all boys believing in that."

He added: "Unfortunately in the first game, we made a mistake and it cost us very dearly.

"He did a great job with the Socceroos. Had we held on or won the game against Ghana or had Germany beat Ghana by a lot more in their final game, we would have qualified to the next round.

"We would have played the USA, might have played Uruguay - who knows?

"Did he do a good job? Yeah. Did we do a good job in that first game? No, we didn't - and that's what killed our tournament.

"Had we gone on to qualify from the group and gone on to great things, you would have been calling Pim one of the greatest managers ever to coach Australia.

"Tactically, he got us to the World Cup so he must have been doing something right, and he was making the best decisions he could with the squad available to him.

"Did he play the exciting football we like seeing in the English Premier League every week? Probably not. It was effective in every other game than the Germany game.

"Could we have done things different? Of course but you can only judge that afterwards."

He added: "What did Germany do next? They beat Argentina by a helluva lot, they beat England, they embarrassed teams.

"So we lost 4-0 but in the end that didn't look too shameful because we had 10-men. There's so many ways you can look at it.

"But it's just unfair to make me a scapegoat and say that I've undermined a manager and said Pim's a bad manager. That's not true. He had one bad game out of 16.

"I didn't want to make a big deal out of this but it's my name that's at stake now. I know that I can look Pim in the eye and know that I did everything for my manager when I was at the World Cup."



Interesting article this one.

When I used to write on Science of Football, only Gerard Whately in the Australian football media saw value in Pim Verbeek's tenure as Australian coach besides yours truly.

In this aforementioned article, Lucas Neill, raises some of the same arguments we did extolling a number of benefits of Pim's Socceroo coaching tenure.

I have just revisited the statistics (updated) my former learned colleague from SOF discovered. The stats support Whately's, Neill's and my perceptions of his tenure.

Verbeek is effectively Australia's most successful coach ever in terms of number of points accrued per game for coaches who coached the Socceroos with over 20 games in charge.

Verbeek averaged 1.91 points per game from 33 games in charge.
Farina averaged 1.91 points per game from 58 games in charge.
Venables averaged 2.09 points per game from 23 games in charge.

Even Hiddink only averaged 1.92 points per game from 12 games in charge.

Given Pim had no games playing against any Oceania nations, like the other 3 coaches with good records, his record looks even better.

Of course a cogent argument can be mounted that Venables was more successful because he accrued more points per game. Nevertheless, he failed to qualify for the WC in the biggest game the team played under his tutelage. I think he played games against Oceania opposition too.

Given Pim was the only coach who had to play difficult games in harsh climatic conditions, unfavourable times for Euroroos' body clocks, with jetlagged players, all these games being WC or Asian Cup qualifiers, it provides food for thought.

Why did so many in the Australian media condemn a coach for 20 minutes against Germany, as Neill suggests?

Why didn't they evaluate his tenure over the 33 matches as Neill, and yours truly a year ago, suggest?

Do we have a mature football media in this country?

Suddenly Bosnich and Foster wanted to sack him after the the German game. I can't remember either of them rescinding their views after they may have been a tad impetuous when the dust settled subsequent to the games against Ghana and Serbia.

Even then, let's say you're a midfielder playing from the start you are naturally going to pace yourself to stop yourself blowing out 30 minutes in. If however you're a striker thrown on for the last 10 minutes you can absolutely bust a gut and immediately find yourself on top of these wonderful stats.

They are peak speed, recorded through the gps receivers strapped to the upper back. No player can cheat in bludging in one area and blooming in another, as the gps is capable of recording everything you do on the pitch and for how long you do it.

And maybe in the future, even the frequency, volume, pitch, carbon dioxide content and stench value of a player's farts.

How many minutes did McDonald play? Are the 'fastest' stats based on average speed or peak speed? Do they take into account metres covered. Etc.


Good questions, Dave.

I assume peak speed.

Andy Harper or Simon Hill alluded to this on Fox at the Asian Cup. All three of our quickest players were recorded as quicker than any Japanese player. I found that interesting, because many of us have thought Japan is a quicker team than Australia.

After I heard the stats, like the Kevin Nolan passing scenario in the EPL, I've noted that Kruse often seems able to beat players and draw fouls. The stats have drawn my attention to Kruse. I scrutinise this facet of his game more closely since hearing the stats.

In terms of stats I've taken for the Socceroos over the last few years, very few of our regular players beat players one on one, other than Archie, Carle, Emmo and Carney. It is the new guys coming into the team who are providing dribbling impetus -Kruse, Zullo, Vidosic and Troisi.

Tackles seemed a poor indicator too. There was the awkward issue of the great Italian defender Paolo Maldini. “He made one tackle every two games,” Forde noted ruefully. Maldini positioned himself so well that he didn’t need to tackle. That rather argued against judging defenders on their number of tackles, the way Ferguson had when he sold Stam. Forde said, “I sat in many meetings at Bolton, and I look back now and think ‘Wow, we hammered the team over something that now we think is not relevant.’” Looking back at the early years of data, Fleig concludes: “We should be looking at something far more important.”

A number of print media pundits were waxing lyrical about Patrick Kisnorbo when he scored goals for the Socceroos, won a lot of headers and won some physical tackles. They seemed to think he was a good defender.

Jade North was criticised more often by fans and print media.

North hasn't need to tackle anywhere near as much as Kisnorbo. His positioning has been better and he has been able to recover much more quickly. He is much more adept at facing slick combination play on the edge of the penalty box, which Korea and Japan do well.

Conversely, Kisnorbo needs to see the play well in advance. North would probably be unsuitable as a CB in the very physical Championship and SPL, where Paddy has done well . The stats show North is a useful player against nimble Asian opposition for the Socceroos, even though he couldn't consolidate a career in Norway and Korea.

Kisnorbo also struggled with the ball at his feet in playing out from the back compared to most of our other CBs. He needs more time and space on the ball. The stats consistently support this. I was surprised Verbeek selected him at all as he has great strengths [b]and
weaknesses.

[b]Fleig gave me the sort of professional presentation you’d expect from a “quant” in an investment bank. Lately, to his excitement, City had acquired stats on every player in the Premier League. Imagine, said Fleig, that you were thinking of signing an attacking midfielder. You wanted someone with a pass completion rate of 80 per cent, who had played a good number of games. Fleig typed the two criteria into his laptop.

Portraits of the handful of men in the Premier League who met them flashed up on a screen. A couple were obvious: Arsenal’s Cesc Fàbregas and Liverpool’s Steven Gerrard. You didn’t need data to know they were good. But beside them was a more surprising face: Newcastle’s Kevin Nolan. The numbers wouldn’t immediately spur you to sign him. But they might prompt you to take a closer look.

In recent years, after many false starts, the number-crunchers at big English clubs have begun to unearth the player stats that truly matter. For instance, said Fleig, “The top four teams consistently have a higher percentage of pass completion in the final third of the pitch. Since the recruitment of Carlos Tévez, David Silva, Adam Johnson and Yaya Touré to our football team, in the last six months alone, our ability to keep the ball in the final third has grown by 7.7 per cent.”








Kevin Nolan is not as renowned as Steve Gerrard and Cesc Fabregas. The stats show up the unexpected.

For Australia Culina, Grella, and probably Valeri, are much higher than 80%.

I have used stats for passing in the attacking and defensive halves. I have not gone as far as different thirds of the pitch. Stefcep suggested this.
It is fairly difficult to determine. I have compiled defensive and attacking pass rates though. Defensive mistakes can be critical. Mishit passes in the attacking third often have little in the way of repercussions.

When look at the aforementioned article, it is interesting that Ferguson made a decision on Staam based on stats. He incorrectly read the wrong data. Staam hadn't declined in number of tackles per game.

There are a number of Australian players who the public has had very strong opinions on at times. The print media in Australia is nowhere near as good as the TV media on footbal.

Apart from Les Murray, the bald guy from SBS and Simon Hill, just about all the commentators on Fox and SBS are former Socceroos or people who have played the game at a high level. The commentary reflects this.


The public/print media have often had very strong opinions that these players are substandard:

Jade North

Richard Garcia

Brett Holman (before the last World Cup)


The print media/fans have often had very strong opinions that these players are very good footballers:

Tim Cahill

Harry Kewell

Mark Viduka

Paul Okon

Ned Zelic

Nick Carle

Patrick Kisnorbo



The print media/fans have strong opinions on these national team coaches:

Verbeek

Hiddink

Venables

Arnold



When one looks at the stats on players/coaches things become more nebulous.

You've become so punch drunk over this debate you've forgotten who is banging on about the importance of coaching licences.

So allow me to remind you; it's your crutch, not mine.

You need to think of coaching a team as a big jigsaw puzzle. Many parts, many shapes, sizes and a myriad of other variables. Having a licence or certificate of attendance in your backpocket is next to worthless if you don't have the skills (especially communication skills) to put the puzzle together.

You need to keep in mind, decentric. Like a driver's licence, any wombat can get one (even asians with beige camrys and a stuffed nodding chihuahua) .

I go to all the FFA free seminars and workshops from national coaches/presenters in Hobart. I also attend local free coaching workshops on offer from state FFA.

I also seek advice from two current/former international coaches and one KNVB instructor based in Holland. I also seek advice from local coaches more knowledgeable than me in specific areas.

I acknowledge I still have a lot to learn, like most coaches. As soon as any coach/teacher thinks they know it all, they stagnate.

Hands on coaching is good if based on sound coaching tenets and methodology.

What do you think of some of the aforementioned luminaries use of stats, Judy?

Someone like Ian Ferguson - who the players seem to like and get along with - IMHO probably has more potential to eventually succeed improving via courses on tactics and training than say a Smith or a Steve McMahon, who could be the greatest tacticians on earth if they wanted to but won't be a successful manager if they can't control players, communicate clearly, or gain trust.

It's not just about having the best tactics and demanding that all and sundry - from the board to the players and affiliated junior clubs - change to accommodate your new standard. It's about being able to effect that with personal skills, tact, and leadership. Some people just don't have that ability. The joke used to be at Glory that Ron Smith's laptop ran the game - because that's pretty much all he ever talked about in press conferences. "Erm well we dominated all the statistics - possession, had nice triangles, had excellent passing percentage, so it evidently comes down to luck that we didn't win".

Others like Mourinho - well, it's not often you make the president of Real Madrid look like a fool and get away with it :lol: Guus is another good example - liked by his players, commands respect, and evidently knows his shit.

I think Ron Smith is considered a better development coach of youth than as a senior results based coach.

The margins for success and failure are so tiny if one reads Soccernomics.

Many punters, particularly some on other forums, think I'm mad collating/analysing stats.

Simon Kuper's article was sent to me by a coach of a senior international team.

“Abu Dhabi Travellers Welcome”, said the message on the façade of City’s sky-blue training centre. Abu Dhabi’s ruling family owns Manchester City, and one thing it has done since buying the club is hire a large team of data analysts. Inside the building I found Gavin Fleig, City’s head of performance analysis, a polite sandy-haired man in a neat black City sweater. Hardly anyone outside Carrington has heard of him, and yet Fleig is a prime mover in English football’s data revolution. Largely unseen by public and media, data on players have begun driving clubs’ decisions – particularly decisions about which players to buy and sell. At many clubs, obscure statisticians in back-rooms will help shape this summer’s transfer market.

Fleig gave me the sort of professional presentation you’d expect from a “quant” in an investment bank. Lately, to his excitement, City had acquired stats on every player in the Premier League. Imagine, said Fleig, that you were thinking of signing an attacking midfielder. You wanted someone with a pass completion rate of 80 per cent, who had played a good number of games. Fleig typed the two criteria into his laptop. Portraits of the handful of men in the Premier League who met them flashed up on a screen. A couple were obvious: Arsenal’s Cesc Fàbregas and Liverpool’s Steven Gerrard. You didn’t need data to know they were good. But beside them was a more surprising face: Newcastle’s Kevin Nolan. The numbers wouldn’t immediately spur you to sign him. But they might prompt you to take a closer look.

In recent years, after many false starts, the number-crunchers at big English clubs have begun to unearth the player stats that truly matter. For instance, said Fleig, “The top four teams consistently have a higher percentage of pass completion in the final third of the pitch. Since the recruitment of Carlos Tévez, David Silva, Adam Johnson and Yaya Touré to our football team, in the last six months alone, our ability to keep the ball in the final third has grown by 7.7 per cent.”

Wenger used the Top Score computer program while at Monaco in the late 1980s

That stat had not necessarily driven their recruitment, Fleig cautioned. Indeed, there are probably clubs that lean far more on stats than Manchester City do. I recently toured several actors in football’s data revolution, and was struck by how far it had progressed. “We’ve somewhere around 32 million data points over 12,000, 13,000 games now,” Mike Forde, Chelsea’s performance director, told me one morning in February in the empty stands of Stamford Bridge. Football is becoming clever.

Dennis Bergkamp: Wenger would produce the stats: ‘Look Dennis, after 70 minutes you began running less. And your speed declined’ Probably ever since the personal computer arrived, a few pioneers in football have tried to use data to judge players. Among the first was Arsenal’s future manager, Arsène Wenger, an economics graduate and keen mathematician. In the late 1980s, as manager of Monaco, Wenger used a computer program called Top Score, developed by a friend. A less likely pioneer was the late, great vodka-sodden Ukrainian manager Valeri Lobanovski. When I visited Kiev in 1992, Lobanovski’s pet scientist, Professor Anatoly Zelentsov, had me play the computer games that Dynamo Kiev had developed to test players. When Lobanovski said things like, “A team that commits errors in no more than 15 to 18 per cent of its actions is unbeatable,” he wasn’t guessing. Zelentsov’s team had run the numbers.

But the broader breakthrough came in 1996, after the Opta Index company began collecting “match data” from the English Premier League, explains the German author Christoph Biermann in Die Fussball-Matrix, the pioneering book on football and data. For the first time, clubs knew how many kilometres each player ran per match, and how many tackles and passes he made. Other data companies entered the market. Some football managers began to look at the stats. In August 2001 Manchester United’s manager Alex Ferguson suddenly sold his defender Jaap Stam to Lazio Roma. The move surprised everyone. Some thought Ferguson was punishing the Dutchman for a silly autobiography he had just published. In truth, although Ferguson didn’t say this publicly, the sale was prompted partly by match data. Studying the numbers, Ferguson had spotted that Stam was tackling less often than before. He presumed the defender, then 29, was declining. So he sold him.

Distribution of play. This graphic shows the geographic location on the pitch of all actions, such as passes, free kicks, dribbles and tackles, occurring during the Champions League Final. The left half of the image shows Manchester United’s activity; the right half shows Barcelona’s. The height of the spikes is determined by the number of actions that took place in individual locations on the pitch. The densely packed spikes on the right show that overall Barcelona’s activity was much more intensive than that of Manchester United As Ferguson later admitted, this was a mistake. Like many football men in the early days of match data, the manager had studied the wrong numbers. Stam wasn’t in decline at all: he would go on to have several excellent years in Italy. Still, the sale was a milestone in football history: a transfer driven largely by stats.


At Arsenal, Wenger embraced the new match data. He has said that the morning after a game he’s like a junkie who needs his fix: he reaches for the spreadsheets. In about 2002 he began substituting his forward Dennis Bergkamp late in matches. Bergkamp would go to Wenger to complain. “Then he’d produce the stats,” Bergkamp later recalled. “‘Look Dennis, after 70 minutes you began running less. And your speed declined.’ Wenger is a football professor.”

Few would suspect it of West Ham’s new manager “Big Sam” Allardyce, and yet his somewhat neolithic appearance also conceals a professorial mind. As a player, Allardyce spent a year with Tampa Bay, Florida, where he grew fascinated with the way American sports used science and data. In 1999 he became manager of little Bolton. Unable to afford the best players, he hired good statisticians instead. They unearthed one particular stat that enchanted Allardyce. “The average game, the ball changes hands 400 times,” recites Chelsea’s Forde, who got his start in football under Allardyce. “Big Sam” would drum it into his players. To him, it summed up the importance of switching instantly to defensive positions the moment the ball was lost.

More concretely, stats led Allardyce to a source of cheap goals: corners, throw-ins and free kicks. Fleig, another Allardyce alumnus, recalled that Bolton would score 45 to 50 per cent of their goals from such “set-pieces”, compared with a league average of about a third. Fleig said, “We would be looking at, ‘If a defender cleared the ball from a long throw, where would the ball land? Well, this is the area it most commonly lands. Right, well that’s where we’ll put our man.’”

In 2003, football’s data revolution got a new impetus from across the Atlantic. Michael Lewis published his seminal baseball book Moneyball, and some people in English football read it and sat up. Moneyball recounts how the Oakland A’s general manager Billy Beane used new stats to value baseball players. Aided by data, the little A’s briefly punched far above their weight until bigger clubs began hiring statisticians too. The Boston Red Sox, owned by John Henry, himself a “numbers guy” who had made his fortune trading commodities, won two world series using “Moneyball” methods.

This February I visited Beane at the Oakland Coliseum. We spoke in what looked like the junk room, but is in fact the dingy clubhouse where the A’s players change. Beane – soon to be portrayed by Brad Pitt in the movie Moneyball – was keen to talk about the data revolution in soccer. Like many Americans this last decade, Beane has embraced the European game with the almost unhealthy fervour of the convert. He can often be found sprawled on a dilapidated sofa in the clubhouse watching European soccer matches.

Oakland A’s baseball players have been constantly ‘valued’ using stats He believes that just as baseball has turned into “more of a science”, soccer will too. Beane said, “If somebody’s right 30 per cent of the time using gut feel, and you can find a way to be right 35 per cent, you create a 5 per cent arbitrage, and in sports that can make the difference between winning and losing.” If using numbers gives you an edge, then everyone will end up having to do it, Beane thinks.


Mike Forde, who had studied in Beane’s hometown of San Diego and followed American sports, made the pilgrimage to Oakland to quiz Beane about the uses of data. That proved tricky: Beane spent the first few hours of the conversation quizzing Forde about soccer. “In the last half an hour I managed to turn it around to talk about his role in baseball,” laughs Forde. He became friends with Beane, as did the Frenchman Damien Comolli, a former assistant of Wenger’s. In 2005, Comolli became director of football at Tottenham and began using data there.

Comolli’s three years at Spurs encapsulated many of the early struggles of the data revolution. British football had always been suspicious of educated people. The typical football manager was an ex-player who had left school at 16 and ruled his club like an autocrat. He relied on “gut”, not numbers. He wasn’t about to obey a spreadsheet-wielding Frenchman who had never played professionally himself. Comolli was always having to fight “nerds versus jocks” battles. With hindsight, he unearthed some excellent players for Spurs: Luka Modric, Dimitar Berbatov, Heurelho Gomes and the 17-year-old Gareth Bale. Yet eventually Comolli was forced out.

There was one question the nerds kept having to answer. Yes, the traditionalists would say, stats may well be useful in a stop-start game like baseball. The pitcher pitches, the batter hits, and that event provides oodles of clear data for nerds to crunch. But surely football is too fluid a game to measure?

There are many obvious irrationalities in football: goalkeepers, such as Brad Friedel, have longer careers than forwards, yet earn less Forde responds: “Well, I think it’s a really genuine question. It’s one that we ask ourselves all the time.” However, the nerds can answer it. For a start, good mathematicians can handle complex systems. At Chelsea, for instance, one of Forde’s statisticians has a past in insurance modelling. Football – a game of 22 men played on a limited field with set rules – is not of unparalleled complexity.


Second, in recent years the fluid game of basketball has found excellent uses for data. Beane says: “If it can be done there, it can be done on the soccer field.” And third, a third of all goals in football don’t come from fluid situations at all. They come from corners, free kicks, penalties and throw-ins – stop-start set-pieces that you can analyse much like a pitch in baseball.

The new nerds could point to so many obvious irrationalities in football, especially in the transfer market, so many areas where smart clubs could clean up. For instance: goalkeepers have longer careers than forwards, yet earn less and command much lower transfer fees. Clubs often sign large players but actually tend to use the smaller ones, having belatedly realised that they have overvalued size. And few clubs have asked themselves even basic questions such as: do they earn more points when certain players are on the field?

Given that you can hire perhaps 30 statisticians for the £1.5m that the average footballer in the Premier League earns each year, you’d think it might be worth paying some nerds to study these questions. Nonetheless, to some degree football’s suspicion of numbers persists. “Letting even a top-level statistician loose with a more traditional football manager is not really the right combination,” Forde once told me. He himself looks like a football man: trim, greying, regional accent, nice suit. That helps him sell numbers to old-style football men. But, in many clubs, the nerds are only slowly gaining power. Probably every club in the Premier League now employs analysts, but some of these people get locked in computer-filled back-rooms and never meet the manager.

That’s why the data revolution was led by clubs where the manager himself trusted numbers. Arsenal and Allardyce’s Bolton began to value players in much the way that financial investors value cattle futures. Take Bolton’s purchase of the 34-year-old central midfielder Gary Speed in 2004. On paper, Speed looked too old. But Bolton, said Fleig, “was able to look at his physical data, to compare it against young players in his position at the time who were at the top of the game, the Steven Gerrards, the Frank Lampards. For a 34-year-old to be consistently having the same levels of physical output as those players, and showing no decline over the previous two seasons, was a contributing factor to say: ‘You know what, this isn’t going to be a huge concern.’” Speed played for Bolton until he was 38.

Passes, touches and goals. Graphic representing activity (from both teams combined) during the second half of the Final. The large spikes are goals; the taller ridge represents touches; the shorter ridge represents passes. The image on the cover represents these events in the first half Football’s shrewdest number-crunchers have always understood that data can only support a decision about a player. They cannot determine it. Biermann tells the story of how Wenger in 2004 was looking for an heir to Arsenal’s all-action midfielder Patrick Vieira. Wenger wanted a player who could cover lots of ground. He scanned the data from different European leagues and spotted an unknown teenager at Olympique Marseille named Mathieu Flamini, who was running 14km a game. Alone, that stat wasn’t enough. Did Flamini run in the right direction? Could he play football? Wenger went to look, established that he could, and signed him for peanuts. Flamini prospered at Arsenal before joining Milan to earn even more.


Conversely, the clubs that stuck with “gut” rather than numbers began to suffer. In 2003, Real Madrid sold Claude Makélélé to Chelsea for £17m. It seemed a big fee for an unobtrusive 30-year-old defensive midfielder. “We will not miss Makélélé,” said Madrid’s president Florentino Pérez. “His technique is average, he lacks the speed and skill to take the ball past opponents, and 90 per cent of his distribution either goes backwards or sideways. He wasn’t a header of the ball and he rarely passed the ball more than three metres. Younger players will cause Makélélé to be forgotten.”

Pérez’s critique wasn’t totally wrong, and yet Madrid had made a terrible error. Makélélé would have five excellent years at Chelsea. There’s now even a position in football named after him: the “Makélélé role”. If only Real had studied the numbers, they might have spotted what made him unique. Forde explained: “Most players are very active when they’re aimed towards the opposition’s goal, in terms of high-intensity activity. Few players are strong going the other way. If you look at Claude, 84 per cent of the time he did high-intensity work, it was when the opposition had the ball, which was twice as much as anyone else on the team.”

Yaya Touré If you watched the game, you could miss Makélélé . If you looked at the data, there he was. Similarly, if you looked at Manchester City’s Yaya Touré, with his languid running style, you might think he was slow. If you looked at the numbers, you’d see that he wasn’t. Beane says, “What stats allow you to do is not take things at face value. The idea that I trust my eyes more than the stats, I don’t buy that because I’ve seen magicians pull rabbits out of hats and I just know that rabbit’s not in there.”


Yet by the mid-2000s, the numbers men in football were becoming uneasily aware that many of the stats they had been trusting for years were useless. In any industry, people use the data they have. The data companies had initially calculated passes, tackles and kilometres per player, and so the clubs had used these numbers to judge players. However, it was becoming clear that these raw stats – which now get beamed up on TV during big games – mean little. Forde remembers the early hunt for meaning in the data on kilometres. “Can we find a correlation between total distance covered and winning? And the answer was invariably no.”

Tackles seemed a poor indicator too. There was the awkward issue of the great Italian defender Paolo Maldini. “He made one tackle every two games,” Forde noted ruefully. Maldini positioned himself so well that he didn’t need to tackle. That rather argued against judging defenders on their number of tackles, the way Ferguson had when he sold Stam. Forde said, “I sat in many meetings at Bolton, and I look back now and think ‘Wow, we hammered the team over something that now we think is not relevant.’” Looking back at the early years of data, Fleig concludes: “We should be looking at something far more important.”
. . .

7 metres per second – the minimum running speed reached by Arsenal’s Thierry Henry almost whenever he ran That is starting to happen now. Football’s “quants” are isolating the numbers that matter. “A lot of that is proprietary,” Forde told me. “The club has been very supportive of this particular space, so we want to keep some of it back.” But the quants will discuss certain findings that are becoming common knowledge in soccer. For instance, rather than looking at kilometres covered, clubs now prefer to look at distances run at top speed. “There is a correlation between the number of sprints and winning,” Daniele Tognaccini, AC Milan’s chief athletics coach, told me in 2008.


That’s why Fleig cares about “a player’s high-intensity output”. Different data companies measured this quality differently, he said, “but ultimately it’s a player’s ability to reach a speed threshold of seven metres per second.” If you valued this quality, you would probably have never made the mistake Juventus did in 1999 of selling Thierry Henry to Arsenal. “For Henry to reach seven metres per second, it’s a relative coast,” said Fleig admiringly. The Frenchman got there almost whenever he ran.
Equally crucial is the ability to make repeated sprints. Tévez, Manchester City’s little forward, is a bit like a wind-up doll: he’ll sprint, briefly collapse, then very soon afterwards be sprinting again. Fleig said, “If we want to press from the front, then we can look at Carlos’s physical output and know that he’s capable of doing that for 90 minutes-plus.”

+33%Manchester City’s David Silva created a third more goal-scoring opportunities than his teammates Just as clubs have learned to isolate sprints from other running, they have learned to isolate telling passes from meaningless square balls. On the screen in Carrington, Fleig flashed up a list of City’s players, ranked by how many chances each had created. One name stood out: David Silva had passed for a third more goal-scoring opportunities than any of his teammates.


The new wash of data has made it easy to compare players to players, and clubs to clubs. Wigan, for instance, were recently conceding a greater proportion of their goals from crosses than any other team in the Premier League. If you’re playing Wigan, that’s handy to know. Increasingly, clubs are acting on the data. A quant has controlled Arsenal for 15 years now, but last autumn the numbers guys took over another English giant. The Boston Red Sox’s owner John Henry, who in 2002 had tried to hire Billy Beane, bought Liverpool and immediately hired Beane’s mate Comolli to do a “Moneyball of soccer”.

From his perch at Anfield, Comolli often chats to the father of Moneyball 5,000 miles away. Beane says: “You can call him anytime. I’ll e-mail him and it will be two in the morning there and he’ll be up, and he’ll e-mail me and say, ‘Hey, I’m watching the A’s game’, because he watches on the computer. The guy never sleeps.” At Liverpool, Comolli has genuine power. He has said that data informed the club’s recent purchases of Andy Carroll and Luis Suarez for a combined £60m.

And football’s data revolution has only just got going. Fleig thinks there is an exciting future in sociograms: who passes to whom, who tends to start a team’s dangerous attacks? If you play Barcelona, that man is obviously Xavi. But in another team, the data may show that the launcher of attacks is someone unexpected. If you know the zones where he puts his key passes, you can try blocking them.
Someone who has thought harder than most about the future of soccer stats is the director of baseball operations at the Oakland A’s. Farhan Zaidi is a round MIT economics graduate with a sense of humour. He’s the sort of guy you’d expect to meet late one night in a bar in a college town, after a gig, not at a professional sports club. For work, Zaidi crunches baseball stats. But he and Beane spend much of their time at the Coliseum arguing about their other loves: the British band Oasis, and soccer. In 2006, in the middle of the baseball season, they travelled to the soccer world cup in Germany together. Zaidi chuckled: “We spend so much time together, that if all we ever talked about was the numbers on these spreadsheets, we would have killed each other a long time ago.”

Because Zaidi knows where the data revolution in baseball has gone, he can make predictions for soccer. The sport’s holy grail, he thinks, is a stat he calls “Goal Probability Added”. That stat would capture how much each player’s actions over his career increased the chance of his team scoring (for instance, whenever he successfully passed the ball five yards forward from the halfway line), or decreased it (for example, whenever his pass was unsuccessful). I asked Zaidi whether one day pundits might say things like, “Luis Suarez has a Goal Probability Added of 0.60, but Carroll’s GPA is only 0.56.”

Zaidi replied, “I tend to think that will happen, because that’s what happened in baseball. We talk now about players in ways that we wouldn’t have dreamed of 10 or 15 years ago.”
In their ancient battle against the jocks, the nerds are finally taking revenge.
