If this is true, then it is a rather strange choice for a player who initially did not want to leave Napoli until he gained more experience after the last bright season. Even though PSG is now building a normal team (without retired stars), Ligue 1 is not competitive and in general a league where you can show yourself or grow. Moving to Ligue 1 from Serie A is a relegation/downshift.
HE wants to leave.
The Napoli's president already said that he will leave in the summer.
