We have players like Grygera, Zebina, De Ceglie, Grosso, Tiago, Molinaro , and members here are expecting Diego to lift the team and play for 2 guys because one of those mentioned was totally out of the game.
Diego was the guy that was working hard , providing some assists, even getting back and playing defensively , keeping the ball when needed, and I clearly can't see why is he the one to be blamed. Maybe the expectations were pretty much high but the overall expectations were unreal (we know that now) and almost every member was expecting scudetto at the end of this season.
