Apart from that, considering that Lunin still wants to leave if he doesn't get the chance to play as a starter, it is very likely that he will move before the summer transfer window closes. He will be the target of many clubs and I think the team that can sign him will be very lucky.
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.
