Dembele's future at the club is uncertain as he enters the final year of his contract, although Spurs are thought to be eager to keep the Belgium international.
However, Dembele himself has reportedly made it clear that he is unlikely to sign an extension with the Premier League outfit, forcing Tottenham to reluctantly consider options for the central midfielder.
However, the report goes on to say that none of those clubs would be willing to meet Tottenham's £30m valuation of the player given that he is now 30 years old and struggled with injuries last season.
Dembele, who joined Spurs for £15m six years ago, is understood to favour a move to Italy, whereas Spurs would prefer to sell him to a Chinese club in order to maximise their profit.
Dembele has made 236 appearances for Tottenham across all competitions.
