Well, he IS good. Find a video on youtube, from a Santos X Flamengo match that happened earier this year (the score was 5 x 4 in favor of Flamengo), the game had some AWESOME goals and Neymar showcases what he's capable of pretty well. Problem is, he's still just a kid, and the hype has gone to his head, so he' turning into one of those onoxious "I'm the best" players, and screwing up a lot, so I think he might fluke depending on the pressure, like Robinho kinda did. As for comparison, he's a lot like Ronaldinho Gaúcho (which is, incidentally, in Flamengo and also makes an appearance in said match vs. Santos) in his early days, this sassy, incredibly fast and really efficient player - on a good day. On the other days, he's just like Robinho, the speed and the skill are there, but he's just gonna
hog the ball until its taken fro him, and take some crap shots at the middle of the goal, which any keeper can save.
