Come on, mate...let's be reasonable, shall we? Two weeks ago Vasco beat Ajax, two months ago Gremio beat Hamburger and i'm not even gonna mention Corinthians and Chelsea.
I'm not arguing that South American teams today stand a chance against the top top clubs like; Barcelona, Madrid, Munich, Juventus and so on...On theory, they don't. (taking into consideration anything can happen in the beautiful game). But there are only 3 or 4 (at the most) top teams in those 4 leagues that are way above while the rest are on the same level or below South American clubs like Corinthians, Boca Juniors, Fluminense, Sao Paulo, etc...
You're overestimating average clubs just for being Europeans, that just isn't right. Plus since you didn't answer my question i take it you don't watch it, so you have no way of knowing how good/bad they really are and make a fair comparison.
About Neymar...Once again, how would you possibly know that? He hasn't gone to Europe yet, that's just speculation. One could say Messi wouldn't be able to replicate half of what he did if he played in a different league. You know, it's easier to be "the man" with team mates like Xavi and Iniesta and to play in a place where no other team besides Real Madrid offers you and your team any challenge.
But then again that would also be speculation. So you get my point, we could speculate anything, yet it doesn't make it true.
