I too was guilty of calling him "Bollock".
But I've totally changed my opinion on him. He said so himself he was stunned at the pace the game was played over here, and he found it hard to adapt. With his time out injured he has analysed the game more and got into his head what he needed to do to be a success at Chelsea. When he came back he looked nothing like the player we saw last season.
Gotta give him credit for his commitment to getting himself back to the player we all know he can be.
