Crunchy no offense mate but you have what normal footy fans call 'Barca fever'. Pepe had Messi in his pocket and had to go, there was no two ways about it. The ref agreed. I'd like to see him score his 'amazing' goals against 11 players when one of them has him locked up tight, ain't gonna happen the same as if Messi came to the PL he wouldn't be scoring goals for fun we have VERY tight defences. I don't count Arsenal in this as Wenger has the same 'we're not worthy' attitude towards Barca as you have.
Man U haven't, and we haven't either. They're very beatable, just don't let them dictate the run of play and they don't know what the fekk to do. Their whole game revolves around getting the ball to Messi all the time. If that doesn't happen, they don't happen. Man U can beat them if they're up for it, or fail abysmally if they're not (they were terrible v Arsenal the other day).
