I guess so. I'm assuming it was a case of deliberately bringing him down (he appeared to grab his ankle), which would be a cynical foul and worthy of a yellow, but again its open to interpretation. I thought it was boring. I would've preferred to see an nice open game with Arsenal able to play the way they normally do. And at 1-0 down they would have had to take the game to Barca. As I said its opinion only. That's why I'm on a forum discussing it with people And yes, I suspect Lehmann knew he was risking a red with that challenge, and can't really complain. But the point remains that if the ref was in any way competent it would've been a completely different outcome (in terms of that incident, and the way the remainder of the game was played). Its a red card offence if he prevents a goalscoring opportunity. He didn't. Guily scored. If the ref had let play go on for two more seconds it wouldn't have been a red card offence. That's the point we're all trying to make.
