Each coach will definitely have quite fundamental differences in training a team so that the patience to see better results must lie with the Barcelona team management itself. Apart from that, it will not be easy for any coach to immediately adapt to the competition in La Liga which is already known for being fierce, especially when Barcelona meets Real Madrid, where next season Real Madrid will still be a tough opponent for any team. However, it is still hoped that Flick can bring more consistent changes to Barcelona's side so that they can perform well in terms of winning trophies in La Liga.
Hansi Flick will have his first season with Barcelona next season and of course we can't all hope too much to see Barcelona immediately rise again in La Liga, Hansi Flick is an experienced coach and comes from Germany so it's very likely that Hansi Flick will try to implement his game style and different game strategies later and of course it will take a lot of time, but to be honest, I hope that with the arrival of Hansi Flick it won't necessarily mean that Barcelona will throw away Tiki Taka as a characteristic of their game so far, because in my opinion Tiki Taka is a football game that quite beautiful and of course quite effective in overcoming any of their opponents.
Hansi Flick may bring many changes to Barcelona next season, but this will not mean that Barcelona will be able to easily compete with Madrid, barcelona deteriorating financial condition is of course the reason that Hansi Flick will not be able to optimize his ambitions with Barcelona, so I think next season we won't see many differences in the competition between Barcelona and Madrid compared to last season, so it is very likely that Barcelona will only try to compete as title contenders but not as title winners in end season.
