Hansi Flick experience with Bayern Munich and the German national team will make it easier for him to organize strategies in the Barcelona squad. He is also an accomplished coach and very skilled at polishing young players into big stars. I think that currently Barcelona is in good hands, Laporta also really believes in Flick abilities and is ready to seek funds to realize his request to bring in new players.
Such things can indeed happen but on the other hand we must also be aware that ultimately for the start of the season our expectations should not be greater because this will be important to make a team or a new coach show his performance including for Flick at this time.
Flick does have experience but in the end this will also be difficult for Flick if he does not have good communication and Enrique and Koeman should be an example where coaches who have experience but do not have good communication in the end it is also a problem.
Now our expectations have to be lowered a little because after all even though Flick's experience is quite large at the moment but we have yet to see the players he will put into Barcelona's plans next season, what schemes they might set and how they perform at the beginning of the season because I think this will clearly determine their steps at the end of the season or at least make the expectations we expect to match the performance shown.
