Sevilla president Jose Maria del Nido is adamant that Geoffrey Kondogbia will only leave for his buyout clause.
The France U20 international has been linked with European giants Manchester United and Real Madrid this week.
Del Nido told reporters : “Kondogbia is not on the market,”.
“But whoever wants him has to pay his €20m clause.
“But please, any team that tries to sign him – don’t. We will consider it an attack.
“I’ve already reached an agreement with [third-party owner] Doyen and Kondogbia will not go this summer.”
