Napoli owner Aurelio De Laurentiis is ready to sell several senior stars over his ritiro row with the squad.
Napoli's players refused to return to ritiro after their Champions League draw with Salzburg last week, which has led to threats to fines and even the potential dismissal of coach Carlo Ancelotti.
Gazzetta dello Sport Dries Mertens is one of the names that will be allowed to leave the club in January, with Inter Milan keen to take on the wantaway Belgian.
Winger Jose Callejon is also reportedly being shown the exit and has attracted interest from China, who'd be able to offer the Spaniard a lucrative deal.
Club captain Lorenzo Insigne could also leave next summer while star defender Kalidou Koulibaly, a long-term target for Manchester United, may be cashed in on.
