Chelsea are reportedly looking at three centre-backs to sign this summer.
Thomas Tuchel wants to sign a central defender to eventually replace veteran leader Thiago Silva.
According to Fichajes, Tuchel has constructed a list of three targets to pursue.
Number one on that list is young French stopper Jules Kounde of Sevilla.
Tottenham, Manchester United and Manchester City have all been linked with the 22-year-old.
Should Chelsea fail in their pursuit of Kounde, Tuchel has also identified his Sevilla teammate Diego Carlos and PSG star Presnel Kimpembe.
