Courtois has been repeatedly linked with a move to Real Madrid.
However, a transfer has failed to materialise and Los Blancos are now closing in on Athletic Bilbao No1 Kepa Arrizabalaga.
LaLiga expert Guillem Balague told Sky Sports: "Courtois is waiting to see what happens with everyone else.
“So, for instance, if Kepa goes to Real Madrid, what will happen to Navas?
“Is Oblak going to go to PSG?
“It's definitely going to be an interesting summer for goalkeepers but it is too early to say what will happen with Courtois."
