In my opinion, Barcelona should have continued with Xavi, because it is not easy to have a coach who will make Barcelona have good results without investing a lot of money in good players, and it seems to me that Barcelona's management wants a coach who manage to make barcelona win the european champions league, i say this because xavi managed to make barcelona win la liga, but in the following season when he was unable to make barcelona do well in the european champions league , the management started to criticize him and even though they weren't very bad in la liga, which in my opinion makes me think that the Barcelona management want a coach capable of making the team win la liga, the European champions' league so they can have more money
and with that they begin to recover the team's finances, as Xavi was not able to make Barcelona go far in the European Champions League and also did not la liga, so the Barcelona management saw that they did not earn much money and That's why they fired Xavi and with this new coach I highly doubt he'll last long at Barcelona, he'd probably only stay for one season and be fired, I highly doubt he'll be able to achieve anything with Barcelona
Barcelona management decision seemed very reckless, they asked Xavi to stay, and afterwards fired Xavi for very unreasonable reasons. However, Barcelona management certainly has many considerations before taking a stand, although on the one hand Xavi dismissal is very regrettable, on the other hand the management wants to protect the club interests in the long term. Management and club officials hope that Hansi Flick can present a trophy for Barcelona every season, so that Barcelona can slowly emerge from the financial crisis. Xavi failed to realize this ambition, which resulted in his dismissal, even though as we know this failure was due to the Madrid factor.
The competition for the trophy next season will be very difficult, even more difficult than this season, because Madrid has reportedly reached an agreement to recruit Mbappe. Apart from anything, Barcelona also has to do something in the transfer window, so that they can compete with Madrid, otherwise Hansi Flick will not be better than Xavi. Concerns about Hansi Flick are very natural, not doubting his tactical quality, but these doubts lie in the depth of Barcelona squad.
