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.
The defending champions of the La Liga Barcelona have not been consistent in their performance that is why many have underestimated them. But to be honest, they’re doing well as they still remain in the second place in the league even after they’re been faced by a lot of critics about their performance. I won’t call them a weak team or an underperforming club, they’re just unlucky not to be in the first position which was caused by their poor performance many weeks back when the league was still indecisive on who will win it.
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.
Yes, Barcelona young stars can help the team go a long way in the La Liga before bringing up another young players to replace them when they becomes unavailable or worn out. I don’t know how long this their financial crises will take them, but they should not fail to build their young players too because it will help them in the long term.
