Sometimes these fanatical fans are always looking for a scapegoat for the defeat of their favorite team and I'm sorry about what happened to Ronald Araujo. In fact, despite Barcelona's defeat against PSG in the Champions League, overall Ronald Araujo is an important player who is irreplaceable and fans only hate him with one mistake out of the many good things he has done for the club.
The very long process of recovering from his injury has also made Barcelona weak in defense and this is quite worrying. What would happen if Barcelona often lost points when facing their opponents and with that, Real Madrid could once again stand alone without any competitors. However, I hope that will not happen to maintain the excitement of the competition for the title and Hansi Flick will likely maximize the depth of his squad to cover that gap.
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.
