Gareth Bale's future at Real Madrid could be decided in Cardiff.
Bale, under increasing pressure over his injury problems, is determined to be fit for the Champions League final against Juventus next month.
However, his recall is facing opposition from inside the locker room, with several senior players insisting Isco should keep his place ahead of the little seen Welshman.
Diario Gol says Bale has caught wind of the comments and has gone to president Florentino Perez with an ultimatum. If fit and coach Zinedine Zidane ignores him for the final, Bale will demand to leave.
Just yesterday, Spain-based pundit Graham Hunter revealed a move to Manchester United for Bale was a definite possibility.
"There is a very real opportunity [with Bale moving to United]. If Gareth Bale decides to press the button and say to Real Madrid 'I would like to go home again' there is a very real possibility of that happening," said Hunter.
