Of course, whether the new coach will succeed in bringing big changes can happen or not. But what we know is that Hansi Flick is a caretaker who is quite experienced in formulating strategies and that will help him enough to bring Barcelona the title. Competition in Laliga will probably be tighter if Girona is able to maintain their good performance this season.
Real Madrid, Atletico Madrid and Girona are the only opposing club that seems to be hurdles for Barcelona next season, perhaps La Liga is going to be really interesting and competitive. Barcelona new coach, Hansi Flick did better with Bayern Munich although things didn't end well for him. Moving to Barcelona means more opportunities for him and he's one of the sincere coaches that will live up to the expectations of the fans. Barcelona trusts him to deliver an excellent job for the club which I'm pretty sure he will without any atom of hesitation or doubt.
Barcelona and Hansi Flick both have no doubts about working together, Hansi Flick is very aware that his job will not be easy when handling Barcelona which is in the midst of a financial crisis, but his belief in being able to handle Barcelona makes him dare to accept the offer. Competition will always be present in the competition, perhaps Real Madrid is the only team that is most difficult for Barcelona to compete with, but it all depends on their performance during the ongoing season. The very experienced Hansi Flick will try to make Barcelona appear more solid, the players he currently has are not too disappointing, he only needs to bring in a few more quality players to add strength to the squad he will lead. In my opinion, Barcelona's performance under Hansi Flick will not disappoint, especially since the squad is filled with quality players.
