Courtois will take part in the Champions League final tonight against Real Madrid.
"At Chelsea I have no emotional connection" Courtois said.
"They signed me up in 2011, nine million euros (£7.25million). Since then I've gone to London only for the medical check.
"Already last year Chelsea no longer wanted to loan. But I wanted to stay in Madrid. After this season, it all goes back over again, and it is probably even more difficult to make a decision."
