Compare the ages of Modric and Cross, and you can imagine how many more seasons Cross can play in Real Madrid if he wants. Last season, Real Madrid did not have Bellingham, and in the new transfer window, Real Madrid can sign a contract with another talented player, this is not a problem when the club has money. Modric is technically a very talented player, this is what allows him to play at such a high level despite his age, but he will not be able to play at this level for a long time.
If he wants to continue his playing career, he will probably have such an opportunity in other championships, but I think that he will simply end his career and rest for a while. I suspect he doesn't want to go to Saudi Arabia for the money.
The productivity of the Wound Modric and Toni Kroos has declined because of their older age factor and for this season the two best homeless people are also often played in the second half by Ancelotti. Having an energetic young midfielder can also make their chances of playing less because coaches definitely need a strong player from everything. Most likely Toni Kroos still has the opportunity to play one to two more seasons at Real Madrid and for Luka Modric like going to end his career at Real Madrid until next season.
If Luka Modric wants to continue his career after ending his contract at Real Madrid, maybe another league like Saudi Arabia still wants to accommodate him. Because the quality of Modric's wounds is still quite good even though the energy has been slightly reduced due to age. Talking about quality in the Saudi Arabian league might be a full mainstay of players who have entered old age.
