Neymar's long time agent and adviser Wagner Ribeiro says Kylian Mbappe should've left PSG.
Mbappe was expected to join Real Madrid this summer, but stunned Spanish football by signing a new three-year contract with PSG.
Ribeiro told Goal: "Mbappé's extension? You cannot know what happened because only those who experienced it from the inside know it.
"What I think is that if I were Mbappé's agent, I would have told him to go to Real Madrid, where he would certainly be very happy."
Ribeiro has worked with Neymar and his father since his time with Santos.
