Actually, I don't really know much about Hansi Flick's playing style, but if you refer to the data you have provided, it is likely that it will work quite well if Barcelona can fill in the existing deficiencies by bringing in players who are targeted by Hansi Flick. In that formation there are Kimmich and De Ligt and I am sure the strategy will work well if these two players join Barcelona. Moreover, with gegenpressing which has been directed by Hansi Flick, everything can be resolved.
It's just that we can't have full hope that this will happen and the same problem is still a hot topic of conversation, so I'm pessimistic about the potential signing. The rest is that Hansi Flick has to make use of the existing squad and even if the results are not as expected, at least he can direct his players slowly.
The only problem Barcelona faces in bringing in new players is their unsolved financial factor. Players like De Ligt and Kimmich can fill Barcelona shortcomings, but to bring them in Barcelona requires large sums of money. Hansi Flick is an experienced coach and he has also managed big teams like Bayern Munich. Barcelona had to make several changes to their squad, such as selling players who had high sales value to get a certain amount of money to fulfill Flick wishes in building the squad under his care.
The signing of Kimmich should be prioritized because he can play in the defensive midfielder position, De Ligt is not really needed because Barcelona still has a stock of quality defenders. Of course Hansi Flick has to take advantage of the squad that Barcelona currently has if his wishes don't go according to plan, one of the advantages is that Barcelona has many quality young players who can be relied on to fill vacancies in several different positions.
