The goalkeeper stated he had "no emotional connection" to the West London side that own him, with rumours flying as to where he'll be playing next year.
The Belgian number one, who was rumoured to be set to seize Petr Cech's goalkeeper jersey next year, may have just burned his bridges a little with his parent side, after a series of comments ahead of the Champions League final.
This three-year spell may be hard to beat for the 22-year-old, whose statements reveal a relationship struggling to get off the ground at Stamford Bridge, but strong with the La Liga side.
"The fans and the other players at Atletico don't see me as a player out on loan," Courtois is quoted as saying by the Mirror.
"At Chelsea I have no emotional connection. They signed me up in 2011, nine million euros. 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."
Now a La Liga title winner, with the possibility to win an even bigger prize in Saturday's Champions League final with rivals Real Madrid, some might say Courtois has every right to feel detached from parent club Chelsea.
The Belgium star has already stated his belief that having both Cech and himself at the Blues next year would be "unhealthy" for the two goalkeepers, and it will be interesting to see where his latest comments leave his future.
Whatever happens, Courtois first has the the biggest of Madrid derbies in Lisbon to contend with, before heading to Brazil with his much-fancied national team for this summer's World Cup.
