Atletico Madrid president Cerezo warns Chelsea: Our players will only leave for their buyout clause
Cerezo declared: "Players play where they want to play and if there's a player who is under contract and wants to play for another team, they already know what they need to do, activate their release clause and leave.
"The transfers are going very well, but I won't name any names, because then the player gets nervous and they leave with a bad feeling.
"For right now, Diego Costa is our player. He's with the national team and when a player is with the national team you can't bother him, we can't say anything and he has to focus on himself, in playing with the Spanish national team.
"We have not spoken with him."
