Arsène Wenger is pressing to change the offside rule in his role as Fifa’s head of global development. The former Arsenal manager wants a player to be onside if any part of their body that can score a goal is behind or level with the relevant defender.

His move follows a series of video assistant referee (VAR) decisions in which goals have been disallowed because a player has been fractionally offside.

A header by Chelsea’s Olivier Giroud against Manchester United on Monday was disallowed because part of his right boot was offside, for example, and Liverpool’s Roberto Firmino had a goal disallowed because of an armpit offside against Aston Villa.

“The most difficult [issue] that people have [with VAR] is the offside rule,” Wenger said at the Laureus Sports Awards in Berlin. “You have had offsides by a fraction of a centimetre, literally by a nose. It is the time to do this quickly.

“There is room to change the rule and not say that a part of a player’s nose is offside, so you are offside because you can score with that. Instead, you will be not be offside if any part of the body that can score a goal is in line with the last defender, even if other parts of the attacker’s body are in front.

“That will sort it out and you will no longer have decisions about millimetres and a fraction of the attacker being in front of the defensive line.”

The Ifab’s general secretary Lukas Brud told Sky Sports News: “There will be no law change regarding offside at this month’s annual general meeting. We welcome Mr Wenger’s views and look forward to discussing it, as a group. But our AGM is a point of discussion on offside and any law change will follow only after further dialogue in the game over the coming months.”

The existing law says: “A player is in an offside position if: any part of the head, body or feet is in the opponents’ half (excluding the halfway line) and any part of the head, body or feet is nearer to the opponents’ goal line than both the ball and the second-last opponent.”

TBH I'm all for it, others will say otherwise.
Whilst watching that chelsea united game that Giroud fantastically taken header of his was a game changer.
Totally ripped when you saw the VAR lines pinging them for a part of his boot/foot just over the red lines.
I remember that Bobby goal as well not too long ago, a little portion of his armpit FFS.

Yer get it changed for next season onwards.

Actually a ridiculous and dangerous suggestion by Wenger.
The rule change he is suggesting is impossible for a human linesman to correctly judge and enforce.
Wengers rule change would mean that no linesman could give an offside and VAR must be used in all instances.
At least the current rule is technically physically capable of being judged by a human,

No it doesn't, linesmen still have their job to call offsides, those mm calls by VAR be it fraction of the boot/armpit/fraction of his ear are the ones most linesmen wouldn't pull up, they should be goals and VAR would confirm it even though the linesmen probably didn't lift his flag.....
TBH I'm a NO VAR in the game, lets the linesmen make the call right or wrong as it once was.
Errors ? yep you live with it get on with the game, what goes around comes around win or lose.

The rule change suggested by Wenger requires the linesman to guess what he can’t see, rather than the current situation where the linesman has to call what he thinks he can see.
Wengers law is flawed in its theoretical basis.
Im not saying it’s good or bad, I’m just pointing out that it is not able to be implemented except by VAR technology.
Theoretically a non scoring part of the attackers body can obscure visibility of a potential scoring part of the body eg an arm can obscure vision of the back etc etc 

I don't see the flaw, the questioned offside still goes to VAR and IF those fine silly lines ie, armpit/a nose etc is over the redline it is judged NOT offside and a goal.
VAR offside rulings needs these corrections imo.
That clears it up for me.

Except the major difference is that the linesman cannot make the call in the first place.
Heres an analogy. Imagine you are standing on one side of a doorway and the door is open and you can see into the room beyond. You are asked to make a decision on what you can see through the open door. Now imagine the door is closed and you are asked to make the same decision on what is happening in the room. You can’t be sure of your decision because there is an obstacle obscuring your vision. You have to guess. It is the same principle. With Wengers proposed law change, the linesman is asked to make a decision with the door closed.
The linesman is asked to see if any part of the attackers body that can legally score is level with or behind the defender. The problem with this is that human beings do not have x ray vision and cannot see through parts of other human beings to what is beyond. You see you can have a situation where a part of the body that is not allowed to score a goal (arm) could be level with or behind the defender, but all of the parts of the body that could score might or might not be in front of the defender, and vision of those parts or vision of the gap’ is obscured by the arm. 

so what do you do.
Everyone will bring up a differing scenario as you brought up above.
People want VAR BUT there is "grey lines" about what is fair what is OTT regards a ruling and a Lino can't see due to no xray vision.
All I'm seeing is just as it before VAR introduced.
A lino can't win, can't please everybody.
What is it with humans today because of tech expect perfection.
Seems its too perfect following the VAR lines judging offside, his armpit as mentioned.
You know what, I'd prefer it dropped and leave football how it was.
Why does it have to be tampered with ? oh because moving ahead we have to ? no we don't.
Leave it as it was, you win some you lose some, thats what has been great about our game.
The hard luck stories - and those who benefited rightly or wrongly might have been the case of relegation and not.
There those - damn they were lucky even though the decision was wrong.
Were human.

Not a offside ruling but another ridiculous decision due to VAR introduced in the game.
From one article :
Crooks believes that Bournemouth have plenty of reasons to be aggrieved as he states he saw Dean wave play on initially, criticising the decision to bring back play 16 seconds later.
SO- ref says play on but he gets notice from VAR person hold on we have an issue that occurred 16seconds ago, ffs.

YafcbY          23rd February 6:29 am                     13                                 I don't travel to football far and wide to watch, to wait, for VAR to decide an armpit is offside, that a shoulder is an arm, to wait and debate what body parts can be considered offside if they happen to be in line with another player.
Football is great, football is dreadful, the referee makes mistakes as do players, managers, even us supporters! We love the game for its drama, for its humanity. This season has been totally ruined by VAR. If we go down, we go down, we are a small club and quite simply can't sustain this level of football (very few clubs can). But to be relegated by VAR, by some inconsistent idiot watching a screen over 100 miles away, what's the point? You may as well just declare a result before the game and save everyone the bother of spending all our money.
We may well be the victims of VAR in terms of relegation. But I think all the football community can overwhelmingly agree VAR is destroying the soul of our game. There are so few things we don't have technology intruding on our lives, a 90 minute football game felt like the last human thing that didn't require it.
Sergeant Blast          23rd February 6:56 am                     5                                 I usually respect Mike Dean for his no nonsense approach. However, the second VAR incident, in particular, was such a big call, he should have viewed the monitor himself.
ieldyperu          23rd February 11:43 am                     4                                 The double whammy has to be checked by ref on monitor. To cancel a goal and award one to the other team? He's bottled it. Why can't refs take responsibility. I watched the var as it happened and thought, no worries there.....and then Dean changes his decision without seeing it himself

Refs need to start stepping in making their own decisions, as I said rightly or wrongly.
Its not suited to the game.

Love Football

I agree. VAR is terrible and should be dropped. Football is not better since it has been introduced, it is in fact worse! I’ve said it is easier to corruptly influence a game since VAR has been around.
It is not going to be scrapped though and we have to live with it.
At the very least, for offsides, the EPL or someone should, in the off season, do some testing and measurements by putting sensors on players and balls to get the average time between the ball leaving a boot and the gap between boot and ball being visible on screen and then adopt that as a margin of error in any future VAR offside calls.

yep as mentioned, it won't be dropped.
Just hope it gets fined tuned some for its not always black and white.
It needs a little "buggery" factor as the game has always had.
