Sevilla President Jose Maria Del Nido has insisted that whoever wants Geoffrey Kondogbia has to pay his release clause.
The French midfielder has been attracting attention from some of the biggest clubs in Europe this summer.
Both Real Madrid and Juventus are said to be interested in the youngster, but the club’s owner has claimed that only €20m will do.
“Kondogbia is not on the market,” he told reporters. “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.”
