Of course, looking at Real Madrid's current strength, it can be predicted that they will be able to defend the Laliga title next season, especially since Barcelona is currently unstable, plus with a new coach, of course Barcelona needs to adapt to a new coach, and this takes time. So as you said, maybe next season no team will be able to compete with Real Madrid, especially in the race for the Laliga trophy.
Currently, there is nothing wrong with the squad. The current players are what the team still need to defend their Laliga and Champions league title next season. No one to be removed and not even one to bring in unless they want to have a replacement for some of the players because of injuries or any future casualties.
In the meantime, Vinicius Jr and Bellingham are all doing great in the tournaments going on (Copa America and Euro 2024). They are the two players who are the top in receiving the Ballon D Or. I want to believe that if they if Real Madrid can defend their titles, they will continue to remain the best team in the world.
Apert from adapting to a new coach, Barcelona is getting choked with alot of injuries and once a player gets an injury there's a decrease olin form which my take Time to recover apert from recovering from the injury sustained in the first place..
Adapting to the new coach might not be as expected seriously., take man City as example , although a good coach will get his team to adapt with in a very short period of time and Pep is a good coach , Flick is also a good coach so I think we should expect fast adaption.
