The agent of Nemanja Vidic has confirmed that his client will decide his future during the summer.
The centre-back's current contract with Manchester United is due to expire at the end of the season, with the club keen to extend his terms.
However, despite the offer from United, Silvano Martina has claimed that the 32-year-old has been approached by a number of other teams.
"The player's contract is expiring but Napoli haven't contacted me," Martino told Radio CRC.
"Man United have offered him a renewal and a number of other clubs have approached him. Offers from Italy? The player wants to finish the season at Manchester United and then we'll see."
Vidic signed for United from Spartak Moscow in January 2006.
