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.
