Yes, Barcelona was very lucky when they managed to get Flick, he is a figure who previously had quite a brilliant reputation. Financial problems are of course an obstacle for him to be able to get new players in the transfer market. However, the current squad is also quite competitive and Flick must be able to manage it well and not completely change the scheme inherent in the Blaugrana, namely tika-taka. Flick must also be able to get support from fans so that it is easy for him to compete with Real Madrid.
Barcelona will compete with other clubs in the league, but my concern is that they will not be able to challenge Real Madrid with their current squad. However, since Xavi is no longer the coach, I believe the new coach will do their best to make Barcelona successful and win the title, allowing them to buy quality players. Let's see Flick's performance next season if he can turn Barcelona to be successful and make the supporters happy, because even the fans don't think they'll do well next season since they don't have key players in the club now if not Yamal and Pedri, that I think they are young and can help Barcelona very well in the feature. but the rest are old and I don't think if they didn't get new players he will definitely be affecting the club performance losing matches and trophies in the competition if they didn't solve the issues.
There is very little chance that Barcelona will be able to compete well with Real Madrid, in fact I doubt that, with Barcelona's current players I don't think they will be able to match the players that Real Madrid has. Apart from that, even though Barcelona already has a new coach, that doesn't mean they will be the best in La Liga, but of course Flick will do his best for Barcelona with the players he currently has, if he can coach Barcelona and make Barcelona compete well with Real Madrid. So it was a surprise because he succeeded in making Barcelona become Real Madrid's rival again. We'll see in the future whether Flick will be able to make Barcelona return to its glory days or not.
The young players that Barcelona has must be the best to be able to return Barcelona to a strong and beautiful team with its performance, even though it is no longer Messi's era, Barcelona fans certainly have high hopes for Barcelona to return to its glory days.
