He will struggle at City initially, but if he doesn't lose confidence and players around him begin to believe in him and run more for him, he could be a gem. He in my opinion tries too many fantastic passes, and a slight majority of them don't come off. Highlight videos show the majority that do, and they are God awful pretty :) But many don't. I love his uniqueness, and would love him here for that. But the dutch league is where he would flourish for a few years before heading to the prem. Those recommending the MLS are wrong in my opinion. The MLS is about Speed, Athletism and graft. He may or may not succeed under those conditions.
His team plays for him often. His movement and decision making is what will eventually make or break him as a player. Movement is fantastic when he is in the mood. His decision making (not is vision, which is fantastic) but the decision to pull the trigger or not. When he gets better at doing the simple slighly more often, he will be great. If he doesn't figure it out though, he'd be good, and the kind of player that runs a mid-range team, and is loved for his fascinating style, but I doubt he'd able to transfer those skills to a top club as he'd be too inconsistent.
I hope he figures it all out and comes here :)
