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.
I disagree with you on this, La Liga title race can easily be predicted knowing to well that two particular teams have been in the dominance of the league for a long time. Real Madrid and Barcelona will always be at the first line when we talk about teams with the winning percentage, ATM have experienced a lot of ups and downs so I don't see them pushing too hard for the league. Valencia used to be contenders too but they are not really in good form lately so I think Real Madrid, Barcelona and ATM have a better chance of winning the League.
