For now, Real Madrid is predicted to return easily to defend the title and dominate La Liga. However, it is also possible that Barcelona will perform beyond our predictions, maybe they will play much better with their new coach, Hansi Flick. Comparing the composition of players from the two big clubs in La Liga, in my opinion Barcelona also still has a good composition of players, it's just that when compared with Real Madrid, it's clear that Real Madrid is still better.
Talking about the experience of the players at these two clubs, in my opinion they are not much different in terms of experience, but again Real Madrid could perhaps be said to have players whose experience is more evenly distributed than Barcelona. What is highlighted is the problem of the players' mentality. I see Real Madrid being more successful in forming the mentality of the players they currently have. Even though they are still young, they have a very good mentality.
With the current squad, of course, Madrid will be able to dominate La Liga again, Madrid has regenerated their current squad by bringing in many talented young players, but by still retaining some old players as mentors in shaping the mentality of their young players, the competition in La Liga will of course most likely still be dominated by Madrid even though Barcelona has now recruited Hansi Flick as a coach, It can be said that Hansi Flick may be able to make a surprise but I think it is unlikely to happen because Barcelona is currently not supported by the quality and depth of the squad that is quite qualified if we compare it to Madrid.
I think ,the players from both teams have the same experience both in the league and the Champions League, but still the quality and performance of the players of the two teams are currently much different not only from the price but indeed in terms of quality it can be seen if the Madrid players are one level above the Barcelona players, Barcelona and Madrid are currently starting to try to build a team by relying on the young squad, but I think the most important thing in the next season is how the two coaches can maximize the performance, mentality and fighting power of the players to be able to compete.
