Although indeed they are now in good prospects and in terms of their performance is quite good but that is not a guarantee to become champions, especially when you see Madrid's readiness.
They may be able to become champions because the chance is still quite big too but on the other hand when they say they are sure they won then don't forget Madrid there which in this case as champions last season are still optimistic to back to back.
Although Barcelona managed to bring in many quality players and managed to show a satisfactory performance in friendly matches. But I agree
with you that it does not guarantee Barcelona can win the La Liga trophy. Moreover, Real Madrid, which is reinforced by Benzema, still has a big
enough chance to also win the La Liga trophy next season. It is still difficult to predict who will actually win the La Liga trophy for the 2022/2023
season, what is certain is that the winner is between Barcelona or Real Madrid. It's too early to predict that Barcelona will be the winner of
the La Liga trophy, we must first see the performance of Real Madrid and Barcelona in the first few La Liga matches first. What is certain is that
the competition to win the La Liga trophy next season will be much more exciting than the previous season. Only teams that are able to play
consistently deserve to be winners. We'll see who between Real Madrid and Barcelona can play consistently until the end of the season.
For candidates, maybe because this will increase their rivalry and be competitive in the league.
Currently Madrid are still the holders of the throne and they are confident enough in their squad that there is no reason to claim the title before the start of the match.
We might be able to do that in the Bundesliga or Ligue 1 but for La Liga it's different.
