The problem now is that some players can't play for them and it's confirmed that Kounde and Araujo can't play now.
Kunde is expected to be out for the next 4 to 5 weeks due to his injury and Araujo is more severe and is expected to be out for 8 weeks for Barcelona.
Obviously this is a loss for them because indeed these two players can be considered vital in their position.
The injury to Jules Kounde and Araujo will not be an obstacle for Barcelona because Xavi Hernandez has other players who are ready to appear to strengthen Barcelona defense such as Christensen and Eric Garcia. Likewise with the news of the injury that befell Frenkie De Jong. Xavi still has Gavi and Pedri who will fill the midfield to help Lewandowski on the front lines.
Xavi can still count on Christensen, Pique and Eric Garcia while Jules Kunde and Araujo are injured, they are very experienced players and can form a solid defense for Barcelona. Xavi will also lose De Jong in the Barcelona midfield, but there are still many stock players who can still be relied on. Dembele also has to step aside for a while, Barcelona still have Ansu Fati and Ferran Torres to fill the position left by Dembele.
Injuries to some of Barcelona's main players will not make the Barcelona squad lose balance, because the quality of the substitutes is almost the same as the main players.
