He's been having a lot of injuries during all this year and that's why he's very out of shape.. also he's not playing in a good level as always. Imo needs a decrease in form (-1/2), IT (B or even C) and speed (mostly ds, because at long runs and turning isn't so bad)
His shape/condition had a considerable decrease last years due to a couple of injuries. He seems slower , even less useful regarding defensive duties and slightly less supportive. Anyways hes still involved in the generation of the game but now in a second place because of Belluschi which is the talisman of the team right now.
