I'm not much of a soccer fan but what is the case for Messi over Pele?
While Pele was the best in his era and won 3 world cups, he never played in Europe therefore he never competed for champions league and never won a Ballon D'Or. Additionally, he doesn't have nearly as much individual/team hardware that messi has.
