Milan are defending well, but they've been abysmal in possession. You can't give Barcelona the ball this easily.
Cassano needs to come off. There's always the chance that he'll do something special, but that's just not a gamble that's worth taking when he's being this much of a passenger. Emmanuelson on? 4-4-1-1 with him and Nocerino wide?
Seedorf has dropped out of it after starting strongly, but that's partly due to having nothing to hit in front of him.
Nocerino is invisible. He'll need to start getting ahead of the ball more now that Boateng's off.
Pato isn't doing enough. Milan really need him to start running in behind.
