Because they have won the Laliga title with poor financial conditions, there is actually a chance for them to repeat that because it turns out it doesn't affect their performance in a certain period and it could be because of their coach, but if this season fails, it's very possible that it won't be entirely because of bad financial conditions faced but also because their arch rival Real Madrid experienced very rapid development beyond expectations even though their main striker decided to leave the club and at that time Real Madrid was in doubt because they only brought in Joselu apart from Jude Bellingham but it turned out that extraordinary developments occurred at Real Madrid including Girona who beat Barcelona twice this season so it looks like Barcelona is experiencing a decline, but next season all teams start from the beginning and the ones who are prepared well will win the title.
Barcelona management not looking with other side because get financial problem and Xavi Hernandez failed defend the La Liga tittle make him sack from his position, actually is unfair what did by Barcelona management because faced financial problem and most of recruitment last season as free agent and loan without spending much money for signing top players. However, with low budget for transfer players, Xavi Hernandez success promoting some youth players and Barcelona had good perform for the first time in last three season qualified to Champion League quarter final round.
I think with new manager for next season if get difficulty with financial condition I doubt Barcelona has opportunity for winning La Liga behind Real Madrid get higher level player recruitment.
I don't think it was because Xavi Hernandez failed to defend the Spanish La Liga title that the club won last season that made the club management sack him. Few months ago, Xavi Hernandez had publicly announced that he's going to leave Barcelona at the end of the season and even reiterated his stance when he said he was still going to leave even if Barcelona wins the UEFA Champions League competition but after so much meetings and pleas from the club management, Xavi Hernandez changed his mind and announced he's not going to leave again.
Recently, there's been some secret disagreement between Xavi Hernandez and the Barcelona president and that was the reason the club decided to sack him and announce his replacement immediately. I think it's a total disrespect to Xavi Hernandez by the club management to try convince him to stay back when they know they'll still sack him.
