I don't think Napoli are ready to lose their keyman to any elite club this summer, they've solid plans for the Nigeria international and keeping him would be their absolute decision.

It's up for Les Parisiens president, Nasser Al-Khelaifi to play his role and also involved the current coach, Luis Enrique to cooperate and tangled good signings.
