Paul Pogba has told Manchester United he doesn't want to return for preseason.
Marca says the midfielder is demanding he be sold to Real Madrid.
While United are not willing to lose him, Real coach Zidane and Pogba are determined to make the transfer happen.
Pogba, who jetted out to Asia this week, is said to have reiterated his wish to United and wants the deal done before he returns to pre-season.
It is also suggested PSG are monitoring the developments closely and could make a surprise move to take Pogba back to his homeland. And while Juventus are keen on re-signing the French international, Pogba wants to join Zidane's revolution at the Bernabeu.
The developments regarding Pogba's agent Mino Raiola means a transfer could be agreed in the near future.
Raiola had been banned from all football activity but that ban has been suspended after an appeal to CAS.
