Dan King of The Sun reported the Belgium international has been offered huge wages in order to tempt him to move to China. It would be the Beijing club's second attempt to sign him after previously failing in February.
Per King, Dembele could reportedly earn £192,000 per week if he departs north London for the Chinese capital.
The midfielder is out of contract at the end of the campaign, allowing him to leave as a free agent next summer. This could prompt Spurs to sell in January, giving manager Mauricio Pochettino the funds needed to sign a replacement during the winter transfer window.
Dembele is an unsung hero in the Spurs midfield, and his Premier League knowledge will be expensive to replace.
The Belgian found himself increasingly on the bench last term, and he might feel the time is right to seek out a new challenge.
Dembele featured in 34 games in the Premier League and Europe last season, but he started 10 matches as a substitute.
As King reported: "Sources say [Beijing] will offer Tottenham between £8 million and £10 million. Dembele is being lured with a three-year deal worth £192,000 a week. Suitors Beijing Guoan, managed by Roger Schmidt, are currently top of the Chinese Super League and have Renato Augusto as one of their permitted overseas players."
£10 million will not get Spurs much in this market, and after making no new signings in the summer, Pochettino might be tempted to make the player see out his deal.
Spurs looked vulnerable as they suffered their first defeat of the new campaign at Watford in the Premier League on Sunday, and the club's lack of depth could become an issue.
If Dembele is offered increased playing time, there's every chance he will extend his stay at Spurs, but he is already featuring in a reduced capacity, making a switch to China on drastically increased wages attractive.
