It is claimed that Sevilla are willing to sell Jules Kounde now. But it looks like Chelsea are not very willing to sign him as they don't want to meet his £68m release clause now. I think that it is really too much for the 22-year-old defender. But Chelsea have no choice rather than this one if they are certain to buy him. I can't actually call this as Sevilla are willing because then they would have a more merciful asking price. 
not only chelsea even according to information from Real Madrid's media goals are also linked with the 22-year-old player, but Sevilla is unmoved by a valuation of €80 million.but so far there has been no official offer only rumors and interest in signing as Monchi said on his official channel which said "Many clubs have asked about Kounde. There is interest, but no official offer."
