I think everything all happened in a short time, probably they did not expect things will end up the way they did, they also didn't expect Messi will leave the club so they were not prepared for his departure but things are finally falling into place once again thanks to Xavi, a lot of improvement has been made compared to the previous season and they can now compete for the league trophy.
Yes, we have to appreciate Xavi Hernandez's performance because he made a lot of changes to the team so that we can see Barcelona as it is today. When Koeman was still in charge, I didn't even expect Barcelona to be able to at least compete in the top 4 of the standings. However, when management decided to put their trust in Xavi. hope reappears with the changes he made. Indeed, I don't deny that at first I doubted that Xavi would make a contribution to Barcelona, but slowly my doubts were answered.
The Barcelona team is now much more organized than before. Their performance is quite stable now. There are still several weaknesses within the party. Xavi is trying to strengthen the team. But Xavi is now trying to win the title. Xavi now aims to win both the La Liga and Europa League titles. How Barcelona will play in the Europa League is still uncertain. Barcelona will play against Espanyol in the next match in La Liga. Hopefully Barcelona will play well and win.
