The absence of Yamal Impacted the game Barcelona seemed lifeless on the right side or center, some players like Lopez, Pedri, De Jong, J.Koude, maybe those are some players that I think were lacking in yesterday's match and some factors that made the goal scored, there was no plan whatsoever implemented by Barcelona and the results we can see in yesterday's match, disappointing maybe but the journey is still long and must remain focused to widen the gap from Real Madrid.
Yamal, Lewandowski and Raphinha are the most important players in Barcelona at the moment. All three are capable of performing well in their respective positions. And if one of these three is out of the squad, its impact can be seen in Barcelona's overall performance. Yamal was not with the squad in the match against Sociedad. So Hansi FLick changed his formation. In this match, Barcelona played in a 4-2-3-1 formation. If Yamal was with the squad, maybe Barcelona would not have lost this match. Since Yamal was not with the squad, Barcelona's attack performance was a bit slow in this match.
It means that Barcelona has a big problem currently, because if any of these three players gets injured, Barcelona is finished and will start losing their matches which is not a good game strategy at all. You don't need to rely on only three players as your key players to the point that one cannot bring out his best without the other. From my own observations, it means that Barcelona has a 50-50 chance of winning Laliga, because if either Lewandowski, Raphina or Yamal gets injured, Barcelona is finished. Flick needs to extend his dependency on other players on the bench and work on them. However, I can understand that Barcelona is still having some financial challenges and buying new players is a problem.
