Xavi is a very experienced and visionary coach. The players he has fielded this season have impressed us with their performances. Many people said Aubameyang was out of the field for a long time. He won't play well in Barcelona. But he is playing well in almost every match.
The Barcelona team has some minor problems. If Xavi can solve these, Barcelona will be a worthy contender for the title next season. Barcelona's defense is weak, they need a new experienced defender
I agree, they need some good defenders. Also, I think the team needs a good midfielder. Actually, the current roster is pretty good, but if this team wants to be the best in the world, there is a lot of development that needs to be improved. That's why they need to add a few people to their roster in this transfer period, they can find good players even if the budget is not too much

even if the composition of the players is as it is today, it is still very convincing to compete for the title next season, Barcelona this season was just a late start and after being handled by Xavi everything changed for the better. but to be able to return to the way it used to be as one of the best teams in the world, Barcelona did have to bring in some star players and fill in the gaps in some of the most important defensive lines.
if Xavi is still coaching Barcelona and given a lot of time to continue to make changes I'm sure there will be many trophies that Xavi will present for Barcelona.
I agree with you on this. He even brought a team that started badly in the league to a very good ranking and achieved a not bad success. While doing this, he succeeded with very inadequate players, now I am sure that he will be much more successful if he can bring better players to the team.
If Xavi coaches this team for a few years, I'm sure they can win the Champions League
