Actually, in some other rumors I read the opposite that he still wants to stay at Madrid and extend his contract, but the decision is ultimately in Madrid's hands.
Sometimes it is quite difficult to predict Madrid's movements especially when releasing a player to be sold to another club because no matter how good their performance is when Perez has acted to sell then the player will leave. Casemiro, Keylor Navas and even Cristiano could leave even though they are still performing very well at Madrid.
The same goes for Lunin now because even though he is playing very well although initially a little doubtful which made Madrid install Kepa at first but we can see that Lunin's contribution to Madrid this season is extraordinary so it is very difficult to let go of a goalkeeper this good especially with his young age. But that sometimes does not apply to Madrid which makes conditions difficult to guess.
Of course, the Santiago Bernabeu team has no intention of selling any core members. But when Courtois was injured and had to be a reluctant spectator until the end of the 2023/24 season, it was thought that the opportunity would come to Lunin. However, Lunin still does not receive absolute trust from coach Carlo Ancelotti. Kepa's appearance causes the Ukrainian goalkeeper to continue to compete for the main starting position. If a club gave him more opportunities to play, I think Lunin would leave Madrid. If Andriy Lunin continues to want to leave, it is necessary that Real Madrid quickly meet that request to provide a satisfactory backup plan for Courtois. Real Madrid still has options from the youth line, the most prominent of which is Fran Gonzalez. At the age of 19, Fran is a long-term candidate to succeed Courtois because he is highly appreciated by the Real youth team.
I just don't think it will happen, especially with Lunin's statements hinting that he wants to stay at Madrid, which clearly proves that Madrid's charm is too great even though it is sometimes difficult to compete.
At present Courtois is 32 years old and that means if you look at the condition of Madrid, actually only a few seasons he can still survive if his performance is still very promising because Madrid sometimes does not hesitate to kick their players when their performance is not very good and this can also be a good opportunity for Lunin so that he can survive because after all it is difficult to release Madrid with the condition of the resources they have.
There is an option where if there is no playing time he can leave, but I don't think that's an option because after all, when he doesn't get the option to play he should be determined to change the coach's judgment in order to compete fairly for the main place in the goalkeeping position with Courtois.
