Real Madrid boss Julen Lopetegui is reportedly interested in signing Marcos Alonso from Chelsea to help strengthen his backline.
Los Blancos have already spent big to bring in right-back Alvaro Odriozola during the summer and now intend to strengthen on the opposite flank.
Spanish outlet Don Balon claims that Alonso has been pinpointed as a solution to Madrid's leaky defence, while also boasting the ability to score crucial goals.
The 27-year-old started his career with Madrid but made just a single appearance for the La Liga giants before moving to Bolton Wanderers, Fiorentina and then Chelsea, where he has thrived in a wing-back role over the past two seasons.
However, the report suggests that the Blues will knock back Madrid's approach as they are unable to bring in a replacement.
