Also, with Barcelona's minimal achievements this season, of course, I think it's still too hard to say Barcelona is one of the best teams. Because after all, in reality Barcelona has experienced more failures such as failing in the Copa del Rey, failing in the Champions League and even worse, even though Barcelona still has a good chance because it is playing in the Europa League, but Barcelona still fails. With results like that, it is certainly not correct to say that Barcelona has succeeded this season, because after all Barcelona is only focused on La Liga, while in reality Barcelona has a good squad.
This is the first full season for Xavi, you shouldn't expect them to win all the tournaments. Moreover, the team's results cannot be good when it is not able to reach the playoffs of the Champions League, and this will significantly affect the team's rating. Xavi needs to step up the attack and keep working, Guardiola with City did not achieve everything from the very beginning, this is an example of how hard work will allow you to achieve your goals.
