Real Madrid are monitoring the progress of young Sevilla centre-back Jules Kounde, sources have told ESPN.

Kounde, 21, enjoyed an impressive debut campaign at Sevilla after joining from Bordeaux last summer for a club record €27.5 million.

The defender made 29 La Liga appearances this term and helped Sevilla to qualify for next season's Champions League.

Madrid coach Zinedine Zidane was interested in Kounde last season and although club captain Sergio Ramosand Raphael Varane are undisputed starters at centre-back, Zidane wants more options for the upcoming campaign.

Madrid signed Eder Militao from Porto last summer and although he gradually integrated into the team, the Spanish giants are still in the market for another defender.

Kounde has formed one of the most solid defensive partnerships in Europe alongside Diego Carlos. Zidane likes Kounde's speed and good positioning on the pitch.

Sources have told ESPN that Madrid are also impressed with Carlos' physique and power but Zidane prefers to sign Kounde due to his youth and room for improvement.
