Berbatov was below par in his first two seasons at United; missed dozens of chances, slowed us down and was average in most games. Guess who's the Premier league's top goalscorer now?
Players aren't all the same, some players need time to adjust, some players don't. Dzeko came from a slower and in style a different league and has moved into a team that is full of new players and lacks the chemistry that Wolfsburg had, he'll take time to adjust his game.
I hope he fails at City, because Dzeko on top form is scary.
