It would be appropriate for Luka Modric to be open-minded because of course he realized that he was no longer young and for example there are other players who can contribute more than he can, I don't think he would mind if he had to be benched. Considering the contribution he has made to Real Madrid, It is very likely that Real Madrid will continue to offer Modric a contract extension, at least Luka Modric still has skills and experience that can be useful for Real Madrid and their young players.
In September, Modric turned 38 years old, and next year his contract with Real Madrid expires, everyone understands that he will not be able to renew his contract with Real Madrid as a player. If Modric says that he is not happy with how much playing time he gets in Real Madrid, then this suggests that he would like to continue playing, and most likely he will consider MSL, or other leagues where he will be offered a good contract.
