I agree with your opinion that the result will be the same unless Barcelona makes major changes in its squad. Real Madrid has opened a huge gap in quality with its rivals, and this is not a gap that can be closed easily. Barcelona will not spend big money on squad restructuring and the gap with Real Madrid will widen. We have not seen anything to the contrary and I think Barcelona is waiting for a surprise and to leave Real behind.
In some seasons, unexpected things happened and we saw many times that the favorite team could not become the champion. It is very difficult for something like this to happen next season, but it is still possible.
Girona showed you last season that Real can be fought, and they didn't have the same opportunities or the bench that Barcelona had, so they couldn't keep up with Real's pace until the end of the season, by the way, Barcelona beat them too. I agree that Real is stronger now, but I don’t agree that Barcelona has no chance, they also have a very good squad of players, Xavi tried to achieve this. The difficulty is that this is the team that Xavi built, and Flick may not agree with all, but for now he has no other choice.
