I don't profess to know everything about tactics and strategy in football, because if I did I'd change my surname to something sounding a bit more dutch and apply for the Socceroos job.

But I do know the Socceroos played a lone striker system last game against Ghana and Harry Kewell was the lone striker.

When Ghana attacked our goal and won the penalty, that came as a result of open play and not from a set piece and Harry Kewell, our lone striker, found himself on our goal-line as our last line of defence!

What was Kewell doing there? Why was he our last line of defence?

This didn't happen with minutes to go before the final whistle when we might throw everyone behind the ball to defend a 1-0 lead.

It happened well before the end of the first half, during which time Harry was our main striking weapon and should have been up the other end of the field playing the role of the target-man.

So what is this system Pim Verbeek has Australia playing called, in which the lone striker drops back and defends his goal-line during open play so early in the game? Does this unique system have a name?
