The 21-year-old goalkeeper has been on loan at the Spanish club for two seasons since signing for the Blues from Genk back in 2011.
And the Belgian shot-stopper has revealed that he is not sure if he will return to Stamford Bridge or be sent out on loan again next season.
“I signed with Chelsea, not just because it is a big club but also because of its commitment to young players,” Courtois told the Independent. “I want to be part of Chelsea history.
“If the new manager says, ‘I want Courtois as my first choice’, that is how it will be. But Petr Cech is a world-class goalkeeper who plays every game at such a high level.
“Chelsea have always been very fair with me and they are also smart people and they know that I need to play.
“I don’t know where that will be but I do know I have proved myself in the two years I have been here [in Madrid].”
