Every clubs have challenges they're facing and looking forward to resolving them. Financial problems could with compromising positions and Barcelona is popularly recognized based on the heavy debts tagged on their name. Xavi Hernandez failed to dominate this season and thereby leading Barcelona out of the glorious path he paved for them the previous season. Barcelona have been through alot lately and their challenges can't be merely won but it comes with consistency in their peak performance.
Barcelona will only be able to show new performance next season if they have found more ways to improve that they need at the moment. Because if the team still has internal problems and the debt is still not settled, of course it will still be quite difficult for Barcelona to produce a brilliant performance next season. Because this season this has really been seen in the La Liga championship so Barcelona still needs new things that can solve the problems they are currently facing.
I think they are going to find a great improvement. The other day I checked if they could just get rid of all the big names and can build an eleven just from their own players, and they could. They have nearly 7 great players who are capable of starting and they would not be all that smart if they kept using players who are all under 20 years old, but they are getting there with some of the players. Plus they have Gavi and Pedri who are doing alright, sure not as expected but not terrible neither.
I think if they get rid of the high paid players, like Ilkay and De Jong and Raphipha and Lewandowski, just get rid of these four then I am sure that they could get a few more good players instead that could really help the team next season.
