The Liga outfit are reluctant to part with the France international defender for any less than his full market value
Sevilla are looking for a deal worth around €80 million (£68m/$95m) if an agreement is to be reached that allows Chelsea target Jules Kounde to leave Estadio Ramon Sanchez Pizjuan, Goal has learned.
Goal was able to confirm on Tuesday that Premier League heavyweights from Stamford Bridge have entered into talks for a France international defender.
Kounde is open to the idea of taking on a new challenge in England, but a transfer will only be sanctioned if the terms are right for his current club.
