Vidic will be out of contract in six months and had been linked with a number of clubs, including the Turkish champions and Barcelona.
Vidic is allowed to talk to foreign sides this month but his agent has denied reports that he has already sealed his Old Trafford departure.
His agent Silvano Martino told Radio CRC that United has offered Vidic a renewal and a number of other clubs have approached him, but ruled out an extension with United at the moment.
Matino further said several teams are looking at Vidic, as he is a very good player and will have no trouble finding a new club, Mirror.co.uk reports. (ANI )
