The Belgian youngster is currently coming to an end of a season-long deal with Real's rivals Atletico Madrid.
However, Courtois has insisted that he is just concentrating on the remainder of the campaign with Atletico.
"These things appear in the press, but I don't know anything," he told AS. "To me the most important thing is Atletico, I am on loan from Chelsea and belong to the English club, but I am with Atletico and am just enjoying myself."
Courtois joined the Blues last summer from Racing Genk.
