Khizanishvili, who is currently plying his trade in Turkey with Kayserispor, is out of contract at the end of the season and would be available on a free transfer.
The news has alerted a host of clubs to his avilability with the experienced Georgia international an attractive proposition on a Bosman.
Norwich, Leeds and Reading are all thought to be keeping tabs on Khizanishvili's situation as they look to bolster their defensive options ahead of next season.
Canaries boss Chris Hughton is aware of the defender's abilities having worked with him during a short spell on loan at Newcastle and he is keen to add some experience to his side at Carrow Road.
Reading know all about the 31-year-old after he enjoyed a spell on loan at the Madejski Stadium during the 2010/11 season, while Leeds boss Brian McDermott is a big admirer of the central defender having worked with him during his time in charge of the Royals.
