Brazilians have some nice defenders yes, but they all play in europe. Neymar cant claim any devine status as long as he isnt playing in europe. But i'm fine with that, players should not move to soon. let them be a bit more mature.
But i tell you this, just like with messi(to a lesser degree since messi is 10x better), he'll have a bloody hard time versus italian opponents.
other teams in europe seemb to forgot how to put a deep defence, close down space, double mark, break buildup, anticipate moves, etc
the only thing messi does against italians, is acting like a playmaker more then a forward, and because of his talent thats still pretty good.
neymar however, doesnt got that. he's far less complete, and will completely choke.
