Speaking of stamina, Luka Modric is still quite fit but has decreased from the previous season, and the playing opportunities that Ancelotti has given to Luka Modric have also decreased if look at the appearances of the 36-year-old player from the 20-21 to 21-22 season. But I have no doubt that I will see him again maybe in the next two seasons with Real Madrid, because Modrid has an important role as you said.
Talking about potential La Liga winners next season, maybe I'm a little doubtful, because on the other hand Barcelona as a rival also made changes in Xavi's hands.
Laliga title race is indeed difficult to predict because Barcelona, Real Madrid and Atletico Madrid have always been strong candidates for Laliga champions. other clubs may not have a chance to shake off their dominance. like Valencia who used to be strong competitors but in recent seasons they have not played well and their performance has dropped drastically. next season several big clubs began to clean up such as Barcelona, Real Madrid and Atletico Madrid.
Maybe you missed one, sevila. Sevila is one of the competitors of the three Laliga giants, even if you look at Sevila's performance in the last three seasons, Sevila always finish in fourth place in the Laliga standings, and it is not impossible that next season Sevila will replace one of Atletico Madrid, Barcelona and Real Madrid. And three teams behind Real Madrid have very slim points this season, only 3 points adrift of second-placed Barcelona, it reinforces that Sevilla could be a barrier next season for all three clubs.
