This time it is different for Barcelona. The Europa League is going to be very important for them because of their financial condition. They have made many signings and there is even a situation for them like they might not be able to sign new players in January.
Considering this fact, they need to make as much money as possible this season. Maybe they didn't play much good in the Champions League. But I still think that they will fight for the Europa League title. Their priority is of course the La Liga title but I don't expect Xavi to focus on only that. Winning both championships would be awesome for them.
If the management of Barcelona were adequate, then they would not have made all these high-profile transfers in the summer. But they did, and little has changed. What can change if they somehow find the money for the winter transfer campaign? Even winning La Liga and the Europa League won't make them run a budget surplus, and they're heavily indebted.
I don't think Barcelona will add more players to the squad in the winter transfer window. Barcelona is now heavily in debt. Debt repayment is a big challenge for them. Now if they are not making enough money to add more players to the squad. Also, I would say that Barcelona's squad is much stronger now. They have no weakness in attack and midfield. However, the performance of their defenders is a bit weak. However, Barcelona has conceded only 5 goals in La Liga so far. But they conceded goals against renowned and big teams. And their performance in the Champions League was poor only because of poor defense. So Xavi will definitely want to strengthen their defense in the winter transfer.
Well, I agree with you, for me Barcelona is not in a position to negotiate any purchase of players, they do not have enough money and this is also something they also did, because when they bought all those players and a great anera because it was not much for spending, but if it is enough not to buy in these mometnes, or rather, after the World Cup is not the idea because they have no capacity and the team has not consolidated well, they do not understand much or really lack much, because the Level has not demonstrated it despite the fact that they go first in the league, but is aspirated as the union of Berlin in the Bundesliga.
Barcelona's current squad is very strong. Still they are not playing well. This is their failure. Barcelona is a renowned team. But their performance in the last two seasons has been very poor. And yet they have not achieved stability. They probably need more time to stabilize. They are not playing badly this season. However, their performance suggests that they have a lot of problems within the team. Barcelona will be stronger and Xavi will be successful only if Xavi can solve the internal problems. Barcelona's current squad is capable of beating any team. Now Xavi has to find his best match strategy. Xavi needs to find a match strategy that the players are comfortable with and can easily adapt to.
