Thibaut Courtois has revealed that his destination for next season will be decided "next week".
As it stands, the 21-year-old is due to return to England in the summer, but it has been suggested that Atletico are attempting to make the move permanent.
"Next week it will become clear where I'm playing next season," he told Sporza.
"It's certain that it will be Chelsea or Atletico and no other club. I can't say much more about it but, in the next weeks, there will be official news."
Courtois has not yet made a first-team appearance for Chelsea.
