The Belgian stopper is currently on loan from Chelsea, but says that he does not want to return to Stamford Bridge next season.
"If I can, I want to stay [at Atletico]," Courtois is reported as saying in The Mirror.
"I am happy, I like my life here and my teammates. It is not just my decision, Chelsea and Atletico also have to talk. But everyone knows I like it here."
The keeper has not played for Chelsea since signing for them in June 2011.
