The talented 21-year old Belgian goalkeeper is in his third loan spell with Spanish club Atletico Madrid but is keen to sort out where he will be playing next season and beyond.
"My agent is currently talking with Chelsea," he told Knack.
Courtois added that he expects to play first team football at Stamford Bridge but is aware veteran Petr Cech still holds the mantle at the Blues.
"I will never say I'm a better goalkeeper than Petr Cech," he added. "But I'm not a player anymore that you can put on the bench, I think.
"I will take that in mind when I take a decision. I can say what I think, but in the end the boss makes the decision.
"Clubs don't take advantage of taking decisions against the willingness of a player, but in the end it stays a game of supply and demand.
"Clubs who are interested have to pay what Chelsea asks, if they want to sell me of course."
