Those who are arguing Neymar is only making a move(potentially) for money are naive in my opinion. Go read the comment sections of Globo and Interativo to get an impression of how excited Brasilian's are at the idea of seeing Neymar escape the shadow of Messi. Detach yourself from the love you have for your club for a moment and think about how the leader of Seleção playing sidekick to best player of Argentina is accepted by us. Messi is your man and so you dismiss any notion that Neymar could approach his class, but Neymar's is ours and we know better. We see what he does when his team plays through him rather than him being forced to play through Messi, and we know he has the qualities to be the best in the world. If PSG can provide him a platform to be recognized as the best in the world, on top of doubling his wages, why would we want any differently for him? Why would he want any different for himself?
And before you lecture me on what playing for Barca means, understand that SA is a half a world away, and that we have our own clubs with storied histories who we support and love. Understand also that we do not view PSG the same as you. Europeans look at the move as a step down, many of us view it as necessary to his development.
