The 24-year-old Welshman has been heavily linked with a move away from north London this summer, despite his current club's constant assurances that Bale remains not for sale.
Manchester United have been credited with an interest in Bale's signature, while Real Madrid have also been monitoring the player's situation at White Hart Lane.
Now, Spanish newspaper El Confidencial is reporting that Carlo Ancelotti is looking to lure Bale to the Santiago Bernabeu with a significant offer that Tottenham will find too difficult to turn down.
Spurs boss Andre Villas-Boas is determined to keep Bale, but might be forced to plan for life without last season's PFA and FWA Player of the Year, if the Premier League side decided to accept their La Liga counterparts' huge offer.
Daniel Levy has previously spoken about the vast amount of money it will take for Tottenham to allow Bale to leave the club this summer, but £85million might just prove to be too much to turn their noses up at.
