Joao Santos, the player's agent, has insisted his client is happy in Naples but seemed aware that the club might sacrifice him for the greater good.
"I think we'll discuss a renewal at the end of the season, as it's not the moment to talk about that, because he still has a long contract," he said. "He wants to stay, although we'll have to see if Napoli agree with that.
"It's an issue of mentality, it's a family at Napoli and they all play for each other. Right now everyone is concentrated on the Scudetto, an objective they've been missing. He has been there for four years now and feels Neapolitan," Santos concluded.
Manchester United look to be the most likely destination, in need of reinforcements with the upcoming departures of Marouane Fellaini and Michael Carrick.
