Hate to tell you this but on the list of Latin players that you say make Juventus so great, you listed Trezeguet. He is FRENCH!!!!!!!!!!! Plays for the french national team.
However, bottom line is, you think South American football is best, I think European is best. There are good players and clubs on both continents and many great players have been left out in this discussion: Daniel Passarella, Jorge Valdano, Claudio Caneja form South America and Luigi Riva, Gianni Rivera, Bobby Moore from Europe. The longer you think about it, the more names come to mind. It's an argument that can never be resolved definitively.
Lets just agree to enjoy watching them battle it out on the field. Good luck to Liverpool in the Champions League and roll on Germany 2006, for which, I am happy to say, I have tickets!!!
