Of course the financial crisis will have an impact on the team's performance. During the financial crisis, Barcelona's performance was often inconsistent. It is true that Barcelona has now brought in a new coach, namely Hansi Flick. However, it is not certain that Barcelona will be able to compete in La Liga next season because Barcelona has difficulty bringing in new players, at best Hansi Flick will use the existing ones and rely on academy players from Barcelona. Yes. I agree, next season Real Madrid will dominate La Liga again, especially since Real Madrid's current front line is very scary for every opponent.
I don't think Barcelona situation will change for the next few seasons, unless they can win big trophies such as the Champions League and La Liga simultaneously. Promoting young players from the La Masia academy is one option, where Barcelona management can release them in the transfer window later to maintain the club's continuity.
Xavi did it with Yamal last season, Hansi Flick will probably still rely on him next season, and give other young players more opportunities. It is indeed very risky to rely too much on young players, but in the long term it is better. Madrid will be very dominant next season, Barcelona must be able to apply as much pressure as possible.
On the other hand, Barcelona losing to Madrid or ATM might be acceptable because they are both elite teams, and they have often beaten each other. But next season, losing to a team like Girona should not happen again, twice in one season, that is completely unacceptable, regardless Girona impressive season.
