Atletico Madrid president Enrique Cerezo won't rule keeping Joao Felix next season.
The Portugal is currently on a straight loan with Chelsea, which he joined in January.
Cerezo insists nothing will be decided until the end of this season.
"At the moment he is on loan to Chelsea, after the season we will sit down and find out what needs to happen," said Cerezo.
"He is a player with great quality and he has the potential to become a great star, but he has a lot to learn."
