Xavi leaves a lot of convenience for Hansi Flick in continuing and improving Barcelona performance next season, hansi Flick of course now has a team that is actually strong enough to compete next season, so Hansi Flick only needs to adapt his strategy and style of play to the Barcelona squad this time in my opinion, next season, I personally hope that Hansi Flick will try to focus more on the domestic league than the Champions League next season because in my opinion their squad is not capable.
Barcelona finances which are in a bad condition, will of course prevent Hansi Flick from building his squad, so it will be difficult for Hansi Flick to optimize their players to compete in La Liga and also the Champions Leagues imultaneously, so that's why it's better for Barcelona to focus on La Liga is in order to break Madrid dominance in the future, with the current financial situation of course we shouldn't expect any fantastic transfers from Barcelona in summer seasons.
I can't really comment much about Hansi Flick's performance in Barcelona because of the current squad he has. It's not that the players Barcelona has are bad, but the truth is that it will be really hard for them to compete with Real Madrid next season. Real Madrid is far better than Barcelona with their current squad. I know that Hansi Flick may try his best, but I can't really say it will meet people's expectations. This financial issue that Barcelona is facing will really drop their performance in La Liga and other competitions. Barcelona really needs some quality players to strengthen their squad, but they lack the money to purchase them.
