Modric has no where to go again many player in his age range already retired but I think Realmadrid still needs him as an experience player so I think he's probably gonna complete his entire career in Realmadrid, he's a absolute legend.
I don't think it's about him playing with kylian Mbappe,I think they just found potential in him when it comes to big games so they would use anything to keep him from retirement.... until he's completely due for it
If Ronaldo was able to join Saudi league then Modric can also join and play for a few years hopefully that’s if any team wants his services. Staying an additional year at Madrid might actually end all hopes of other team seeking his services, he has no much years left but i still believe he can still play for as long as he want because the performance he showed at Euro before being eliminated was unbelievable for a player at his age.
Playing with Mbappe will be fun for them and but i still think he will play most of the season sitting at the bench
