The Sun claims that, while Spurs remain desperate to keep the Welshman, they privately acknowledge that failing to qualify for the Champions League would make his exit all but inevitable.
However, chairman Daniel Levy is adamant that it will take a world record transfer fee to get the 23-year-old.
The main contenders for Bale's signature are Manchester City, Bayern Munich and Real Madrid, who paid the current world record fee of £80 million in 2009.
Just 24 hours earlier, The Sun valued Bale at a relatively modest £30m - while the Sunday Mirror says Spurs would consider a £65m offer.
This fluctuation is typical of reports about Bale, and leads you to question whether anyone really knows anything at all.
When we asked Eurosport's pan-European network earlier this year, they all valued Bale between £34m and £47m - so Tottenham could struggle in their efforts to recoup more than twice that amount for the winger.
Elsewhere, The Mail on Sunday claims knowledge of a £23 million escape clause in Marouane Fellaini's contract that would make Everton powerless to stop him leaving for Chelsea, Zenit St Petersburg or Anzhi Makachkala.
The Sun says that AC Milan will try to sign Manchester City's Micah Richards after receiving a personal recommendation from Mario Balotelli.
And The Sunday Express says Manchester United have given up in their pursuit of Borussia Dortmund striker Robert Lewandowski, who is expected to join Bayern Munich this summer.
