Rivaldo says Neymar cannot fulfil his potential in Paris.
"I have already said that Neymar can be the best player in the world, but I think that if he stays at PSG he won't achieve that," the retired footballer explained in an interview with Globoesporte.
"He has to leave PSG.
"Ruling out Barcelona because of what happened there, and according to the information that I've heard from close people, I think he has a chance of going to Real Madrid, given all I have heard recently.
"And I think that he could indeed become the best in the world there."
