He's epic at most of his game, and the bits he was utterly dire at, he is improving rapidly on, people say Mourinho was wrong to get rid, but I disagree, his first touch was not good enough for their style of play, and likelihood is he would of not got many games and ultimately faded into obscurity, sold to some jarg european club for a minimal fee where his poor touch would be expected and he would be years behind where he is now.
As it is, he's been given game after game where he has had no choice but to address the areas he's not great at and has risen to the challenge immensely. Full respect to him and Martinez for coming here.
