It is unlikely that Flick will be able to increase anything, since he refused new transfers, given the financial situation of the club. Injuries will happen in any case, and of course Real Madrid have much greater depth in the squad and the Real bench is very high quality, I think Real could make another very decent team with players on the bench. If Flick faces multiple injuries, it will most likely be an unfixable situation for Barcelona, but there is no need to think ahead, problems need to be solved as they arise. Barcelona has a good squad that can compete even with Real Madrid.
Barcelona actually have a good squad that can compete with Real Madrid but we are talking about here is their plan B when plan A fails. When their major players go in injury especially long injuries, don’t you think of the depth it’ll affect the whole club’s performance. It could happen at the middle of the season and in crucial matches they need to win in order to maintain a good position on the table for the fight of the league title or in other competitions they will be participating it. This financial crisis is taking too long than expected and it’ll affect every coach that comes to manage team unless their plan A doesn’t fail and players are injury free throughout the season.
I didn't see any Barcelona players who could be deployed to compete with Real Madrid next season, because I didn't see any Barcelona players capable of challenging Real Madrid in the Champions League. But I am hearing that Barcelona are interested in Williams athletic player, and I am sure he will definitely help the team if they get the opportunity to buy him. That is when I can say Barcelona will be more stronger next season because he is very skillful and talented, and everyone likes him. He performed very well in the Euro with Yamal, which is why Barcelona are interested in him, and I am sure the boy will like to sign for Barcelona because is very interested with Barcelona since Yamal is in the club and there friends. Barcelona will do their hardest to acquire the player, despite financial constraints. The new coach will do all possible to acquire a new player before the season begins. I think Anso Fati is already injured, and there is a need for fresh, talented players to replace them. Barcelona's dilemma is massive, but I am confident that they will eventually overcome it because Barcelona is a major club.
