Number 9 is not interfering when the cross came in, so we can ignore him.
7 is onside as the ball comes in, and Mane can't be offside when 7 plays the ball as he is behind the ball.
Whilst Mane *is* beyond the defenders (except the keeper), he is not ahead of the ball.yes thank you did not realise that the ball could be pulled back to someone standing offside ?
Law 11 states for an offside to occur:
* any part of the head, body or feet is nearer to the opponents' goal line than both the ball and the second-last opponent.
Does that make sense? I'm terrible at explaining this. @_@
