He has the potential to be a World Star, I think that he should remain at PSG for at least another season. If he goes to somebody like Barca or Real Madrid, he won't get a starting place 100%. This could slow down his career.
Ronaldinho has also realisted that and says he will stays for PSG for another year especially if they make the Champions League so he can get some slight CL experience. Him and Djibrill Cisse are smart "kids" because they don't get themselves into the hype to mess up their carreers and don't seem as spoiled as for example, Javier Saviola although he's doing fine he went to La Liga way too early.
Triple R is going to be very huge and I am pretty sure that Rivaldo, Ronaldo & ROnaldinho will be huge and wait untill the second half when Luizao and Denilson come in the 2nd half, Kaka is another rising star too. :happy:
