Atletico Madrid president Enrique Cerezo has revealed that the future of Chelsea goalkeeper Thibaut Courtois has still not been decided.
The Belgian international has spent the last three seasons on loan at Atletico, whom he helped win La Liga and reach the Champions League final last term.
As it stands, Courtois will return to his parent club for the 2014-15 campaign, but Cerezo is still hopeful that an extension of the loan can be agreed.
"There's a little problem, which is Chelsea," Cerezo told reporters.
"I imagine if Chelsea wants him to stay for the season, they'll keep him and if not, it's best if we reach an agreement, which is to keep him with us for another season."
Courtois is currently with his national team ahead of the World Cup.
