Man of Honour
BaZ87 said:If an outfield player had fouled someone (worth a yellow) and the ref plays the advantage, he then goes back once the ball has gone out of play and books the player that commited the foul. So by the letter of the law if the ref allowed the advantage and let Barca's goal stand, he should still then send Lehmann off. I know it seems harsh but thats the rules.
As I pointed out, the red card was for denying Barca (not the individual) a goalscoring chance. If he'd let the play go on and Barca scored, what did Lehmann deny Barca? The answer is nothing. He should have been booked and the goal stood.
