I really can't understand all that DP critic in here!
He started that season soooo well, was our best player, and than was unlucky as he got injured. Not his fault. He came back, had a bad game, but in the next one, against Parma, he scored a goal and assisted one, and also scored against Olympiakos. After some good performances he again got injured. Again not his fault. But he again came back in form, and even convinced Trap to pick him for EURO. And at EURO he has not been bad. In the first game, every Italien player, beside Cannavaro and Buffon, was weak. In the second, he was Italy's MVP together with Cassano, and against Bulgaria he was unlucky, but played good.
I am 100% sure, that he will shine next season, if he won't get injured again. He hasn't changed, but his health did, and he will always depend on his health.
