I disagree, I understand what you're saying. I just don't think Barca were doing anything extra in the stimulation sense. I thought they could have really gone over the top and rolled about and invited more tackles by him but they seemed more bothered about dominating Arsenal, and seemed to be making a point.
I don't think I remember a single foul where Song even sent a player flying except his cynical first yellow card one. This is the problem with Song, he just gives away utterly utterly stupid fouls. He'll close someone down who has their body between Song and the ball, Song ALWAYS, every single time puts his leg through the player. Its not a hack, its not to knock a player down and he rarely takes players down, he just seems to think he can get the ball by kicking through the player.
Its niggling fouls, he does it constantly, all the time, he should have been sent off and for only one proper foul, the one he got the yellow for was an undoubted yellow, and utterly utterly unneccessary one player, all four defenders back, 30 yards out, no support. The other yellow should have been given for consistant petty fouls, nothing major. LIke you said, I don't think a player went down all night, there was barely any extra time in either half, generally if players are going down left right and centre you'll have more than 2 minutes extra time, I can barely remember the last time a second half had only 2mins added.
I think across both teams I can barely remember a single player going down for more than a few seconds.
Considering Alves/Pedro/Iniesta's diving last year, world cup, and everything in between they were incredibly, non cheaty in the game, Alves especially normally spends more time on the floor than standing in a game.
Barca really do lack when Puyol isn't playing.
I really don't see Arsenal going through though. Barca were just having a bad day... and they should have scored 4 goals, on a bad day.
Not much to do with Puyol, he's decent but one defender can't cover everyone, I've said it previously, theres a point where too many teams just give in before the games even started, won't commit men forward. Attack Barca and they just aren't used to it, its that simple. For 3 years they've barely had to defend, ever, its as much a case of they simple aren't in form defensively.
Plenty of teams catch them out on the counter attack but rarely commit more than 2 players forward in an attack, and rarely with the quality required to take on 2 CB's and a keeper. Commit 6 men to an attack and Barca look pretty hopeless at the back.
