"Playing in Europe is not a factor to evaluate the best football players. "
Playing in Europe is the only factor...it's a way to really show if u really are that good...do u know how many Brazilians or Argentinian players were supposed to be great players and then they came to Europe and they really sucked...so about Neymar until I see him play in Europe I don't really have an opinion about him coz I'm sorry to say it but the Brazilian soccer league is not even close to Premier league, Liga or serie A...

"Maradona well, what a tremendous player, but was he greatest than Garrincha, Zico or even Ronaldo?"
Are u serious? again I know u are Brazilian but come on...Maradona together with Pele' is easily the best player in soccer's history...actually in Europe many people think Maradona was better than Pele'...if u ask me I would tell u I don't know who was better, because Pele' never played in Europe so we will never really know...the world cup alone is not enough to prove that Pele' was the greatest, there has been so many players who played great at the world cups but sucked at everything else or great players who sucked at the world cup but they did great at everything else...so again we will never know...
