I would guess that Barcelona having trouble right now is overestimated. First of all, last year they were the champions, they are literally the latest champions of the league, saying that they are not doing well is unreasonable, secondly they have one year right now where they are not the champions if they lose this season (when they lose it) so it is not a big deal.
On top of that, they are a team with a lot of financial trouble, so they managed to do the right thing and figured out a lot of great young players, they have 6-7 great young players that can play amazingly and I believe that they should be doing fine. I think the best thing to do in this case would be just considering them lucky and they can be doing better next season with what they have.
Now Barcelona is in 2nd place in Laliga, of course this is a good thing because of course there is still hope for Barcelona to become champions again this season.
Although it is actually difficult for Barcelona to become champions because Real Madrid is superior to Barcelona.
However, if you look at Barcelona's finances, I think in this case Xavi has succeeded in bringing Barcelona to success and this season I think Barcelona can be considered successful because currently, even though they are in 2nd place.
However, Barcelona fans definitely want Barcelona to perform better this season and want Barcelona to become champions again this season. However, it seems that Xavi is starting to feel uncomfortable at Barcelona until he finally decides to leave Barcelona at the end of this season. Yes, having young players in Barcelona certainly opens up opportunities for Barcelona to perform better next season, but I think if for example Xavi leaves Barcelona, I don't think Barcelona will necessarily perform as well as it is now because I think Xavi is really needed by Barcelona.
