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.
I think it boils down to the standard of the club. Many football fans will not admit it but Barcelona is among the top 3 biggest clubs in the world. When a club as big as Barcelona has a little failure, it would be viewed as a very huge one meanwhile this is what other teams get a pass for.
Let's put what I mean practically. If you ask any football fan to choose which club has been more successful in the past 10 years between Liverpool and Barcelona, most of them will say it's Liverpool, but are they?
Liverpool has the Champions League in the last 10 years, and Barcelona also has won 1 Champions League in the past 10 years.
In total, Barcelona has won 16 trophies since 2015 while Liverpool has won 7 but because of the standards of Barcelona, this is considered poor. It's the price for greatness, I understand.
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.
Barcelona under the management of Laporta is very well managed. He may have made a few mistakes, which is normal, but overall, the club is heading in the right direction. Look at the signing they make, Lewandoski, Cancelo, Kounde, Gundogan, Felix, Christensen, Raphinha. Also, look at their youngsters. They already have a 9 to replace the aging Lewandoski even though he's still firing. They have a good squad. All they need to do now is get a very good coach if Xavi is truly leaving and they'll be good.
Off the pitch too they've been making very good moves. The renovation of the camp now is one of them. Getting better sponsors like Spotify too is one of them. They're also trying to balance the books and despite the restrictions from La Liga, they're doing well.
Now they're in the quarter-finals of the UCL for the first time in a while and they have a pretty good shot at making the final.
I agree that the problems of Barcelona are overestimated, but it's simply because of how big the club is. This is a club that used to dominate. A club that has the biggest talents in the world. A club like that doesn't win the Champions League in 5 years and it would be a selling headline for every newspaper.
