So far there are not many coaches who have achievements like Xavi, if Barcelona is not at its best then this is due to internal problems which may be financial or other factors. But if it is a financial factor then Xavi has to reduce the players who are quite old, perhaps they can be stopped and replaced by new players who are still young. With this rejuvenation, it is possible that Barcelona's performance will improve again and be ready to play in matches next season.
Barcelona might be able to make some efforts to rebuild its squad whether it is through young players or academy players but their competitors such as Real Madrid continue to progress by strengthening their squad by bringing in great players well, this will make Barcelona always behind because they chose more outdated ways of building a squad. If I were the owner of Barcelona I would have no other way either, unless they let Real Madrid take the lead in the next few seasons.
