With Hansi Flick, Barcelona will try to bring in new players, but they also have to keep important names in the team. Flick also needs to know how to keep players who can be important for Barcelona, because it is critical to keep players who play in their own region, such as Yamal, Pedri, Gavi, Ter Stegen, De Jong, in the team. The team may become even weaker because one or more of these players are sent off from the team.
Hansi Flick will ask Barcelona management and club officials to retain important players, regardless of how they deal with various challenges. It is reported that Barcelona current financial situation is getting worse, let alone recruiting new players, they are currently even having difficulty registering existing players for next season.
Indeed, this situation indirectly makes it easier for Madrid to retain the trophy next season, and I don't think Barcelona fans should be too harsh on Hansi Flick if next season he fails to meet expectations. The financial crisis that hit Barcelona has made their bargaining value decrease in every competition, management must find the best way out to overcome this.
On the other hand, it looks like Barcelona should follow the example of Dortmund in overcoming financial problems, giving more playing minutes to talented young players, and releasing them in the transfer window to make a profit. Barcelona has the La Masia academy, where many talented players have come from there, such as Lamine Yamal.
