Real Madrid have reportedly identified Sevilla's Jules Kounde as a potential transfer target.
Los Blancos could lose club captain Sergio Ramos on a free transfer this summer, while there is also uncertainty surrounding the long-term future of Raphael Varane.
Zinedine Zidane's side are thought to be the favourites to sign Bayern Munich's David Alaba, but the Spanish champions could potentially be in the market for two new centre-backs.
According to Marca, Kounde is an option for Madrid, with the 22-year-old further enhancing his reputation with a string of impressive performances during the 2020-21 campaign.
The France Under-21s international has scored three times in 30 appearances for the Europa League winners this season, including a goal against Barcelona in the semi-finals of the Copa del Rey on Wednesday.
Manchester United have allegedly identified Kounde as their leading defensive target, with Ole Gunnar Solskjaer's side said to believe that an offer in the region of £60m could convince Sevilla to sell.
