Club president Jean-Pierre Rivere and coach Lucien Favre have confirmed the star striker is not expected to renew his deal
Nice expect Mario Balotelli to leave the club when the striker's contract expires at the end of the season.
Balotelli has scored 22 goals in all competitions this season, 14 of which have come in Ligue 1, but Nice are eighth and unlikely to qualify for Europe.
The 27-year-old's agent Mino Raiola has suggested Serie A title contenders Napoli would be "ideal" for his client, but leaders Juventus have confirmed they are not interested in Balotelli.
