Former PSG coach Unai Emery admits he wants to see Neymar return to the LaLiga.
Neymar is a summer target for Barcelona - as confirmed this week by their football chief Eric Abidal.
Emery told Efe: "When I was at PSG, I logically defended the fact of having the best players. Mbappé is French and he must defend France and PSG. There, he has the opportunity to win the Champions League and I think Mbappé is in the right place.
"But now, I watch football in general and being in Spain, I would like to see Mbappé in the LaLiga. He can be the best player in the world and I think he can do it.
"If he came to a leading Spanish team, he could do it."
