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.
