In the league that he is in and the way that he is playing he has a right to be arrogant though. Depending on his mentality he may/may not have to cut it out when he comes over to Europe.
Compare him to 2 players with arrogance that have played in the PL: Balotelli/Ronaldo. One is now comfortably in the top 2/3 in the world (depending on how highly you rate Xavi/Iniesta etc) and the other is only showing flashes of what he can do, albeit looking like he can be a top 10 player sometimes.
Personally, i think he can go on to be one of the best in the world as he seems to have that aura about him.
