It is undeniable that Barcelona's decline in performance is due to the fact that many of their core players are currently injured. No matter how strong the club is, when many of the main team are injured, this will definitely not go well. Moreover, there are 7 players who are currently experiencing injuries. That will definitely have a big impact, because they occupy crucial lines in the squad. Currently, of course Barcelona is also focused on recovering from the injuries of its players, and of course Xavi has a very difficult and confusing job because he has to think about how to survive and still get points. Moreover, there will be El Classico in the next few weeks which will certainly bring its own pressure for Barcelona if they compete without some of their core players.
The next El Clasico match is not a good time for Barcelona. The injury storm is sweeping the Barcelona squad, including Pedri, Frenkie de Jong, Raphinha, Yamal, Jules Kounde, Robert Lewandowski, and Alejandro Balde. In particular, Lewandowski is the leading goalscorer of the Catalan team, but he still needs to determine his recovery date from injury. He will miss a series of important Barca matches. As for Raphinha, he is healthy enough to play in the El Clasico match between Barcelona and Real Madrid.
This is a headache for coach Xavi. Xavi's team has had poor results recently. They let Real regain the top spot and dropped to 3rd place on the rankings. The championship race is increasingly fierce.
