Neyclown looks much more like Robinho in terms of footballing skills than he looks like Ronaldinho
Further, his mental skills doesn't look like Ronaldinho's mental skills. Neymar just doesn't look like he is as intelligent/a strong personality/whatever as Ronaldinho.
He looks more like Inter's Adriano, with whom you never knew if the guy today wants to play a football match or he wants to film a gangster rap videoclip today
Further, currently nothing indicates that he would help us against strong european teams like Bayern.
Yes, against Mallorca he will dribble like crazy.
Against Bayern, he will be surrounded by 4 european defenders and he will just lose the ball.
About Marty McFly, Neymar will not be a total failure, but it is likely that he will be something like Robinho or Alexis.
Chances are not too high that he will be the guy who is worth 57 Millions and who will bring back that XX factor, which we lack currently, to bring us back on the top of Champions league
If you will reply now: But you can never now will he be good or not, then:
1. a history can teach you how many similar players like him were a success and how many were a flop
2. further, even if you want to gamble, then 20 or 25 Millions would be a fair price to gamble with an unproven player like him
-- 57M for a guy like him is a joke and reminds me of a Gaspart's era
