Real Madrid president Florentino Perez is willing to sell Raphael Varane this summer.
Off contract in 2022, Varane is stalling on considering new contract talks with Real Madrid.
Onda Cero says Manchester United are watching developments and Varane is weighing up his options.
However, Florentino is prepared to take the decision out of Varane's hands this summer if he continues to stall. The president will not consider allowing the Frenchman to run down his contract.
Instead, Florentino will sell Varane this summer if no new terms are agreed.
