I am not saying they need it or not. I just have no sympathy for Barcelona in this situation because they set up all wrong.
The foul didn't decide this game, Barcelona have been woeful from kickoff.
Well at the moment, actually, there's a very good chance the foul and the offside goal may decide the game!
As I said, it doesn't matter how bad Barca have been, how good Bayern have been, or what a fair reflection of the scoreline is, the score should be 1-0.
I understand your point a little bit, but I think it's irrelevant.
Edit: Make it 2-0!
