This season is the opposite with Barcelona being more promising but of course performance will determine whether or not the current conditions will be in line with what is expected for Barcelona.
I still expect something interesting from Xabi in his first season although maybe for the CWC he was a bit more pressured but I don't think that's a benchmark so Xabi's chances are still very big for now.
Yes, with the same coach and a squad that is strong enough and has additional strength, I also believe that Barcelona will definitely succeed and become even stronger. For Real Madrid, everything is still being tested because their performance compared to other clubs is quite impressive, although we don't know how Xabi will make their squad no longer as popular as before, it shows that they actually want to be different and remain strong, it's just that often their tactics don't match the opponent's conditions and also in the field Xabi must open again and again as a great coach to rebuild Real Madrid again.
Barcelona already has very good players, and Hansi Flick has been able to manage them well. So far, they have added a little ammunition to their club, making Barcelona increasingly confident that they will continue to show their best performance next season.
Xabi Alonso is still adapting to the new team's conditions. His strategy is still not quite right. He needs to raise his components higher because the team he is currently coaching is at a higher level than before. This is like life and death for Xabi Alonso. If he cannot make Real Madrid perform well and consistently, he may lose the trust of elite clubs (except Leverkusen).
