Los Blancos view the 26-year-old as the perfect addition to provide versatility and cover for the left and right flanks. His inclusion would help offset the departures of Ferland Mendy and Carvajal.
However, the competition is stiff, with Manchester City and Liverpool also reportedly interested. Juventus has placed a release clause between €60m and €70m on the Italian defender, making a deal complex for the Spanish giants.
