Sevilla chief Joaquin Caparros insists Steven N'Zonzi will only leave for his buyout clause.
The midfielder has been linked with Everton and West Ham.
Caparros said, "He has two years left on his contract, I haven't spoken to him but we've been exchanging text messages.
"We're hoping he will be world champion with France. We haven't received any offers for him but I'll say the same as I said with Lenglet, his buy-out clause is 40 million."
