DeSowa is right, CR is not as selfish as ppl make him out to be. He is the sole reason IMO that Man Boo is leading the premiership this season, his goals and assists have them on top, he has definitely grown and matured as a player.
That being said, I still give the adge to Kaka right now, just because of his football intelligence. Grande man said it right, he plays just as much with his brain as he does with his feet, and he has the technical ability to match his imagination.
Watch out for CR tho, if he matures even more and plays a little bit more with his head, I think he would be better than Kaka
