Premier League clubs are queuing for Sevilla defender Jules Kounde.
Okdiario says Chelsea are showing serious interest in the France international, but aren't alone with Manchester United, Tottenham, Arsenal and LaLiga giants Barcelona also in contact with Sevilla.
Kounde has a contract with Sevilla until 2024 and a buyout clause of €80m.
Sevilla would be willing to sell closer to €40-50m this summer.
Chelsea boss Thomas Tuchel is a fan of Kounde, having been aware of him during his time with Bordeaux, and the former PSG coach is eager to bring the stopper to London this summer.
