The fact is that Barcelona continue to have problems in defense. Two goals conceded against a clear underdog is a bad sign.
It's funny that when Rashford was on the field Barcelona got a score of 0-2, and when he was substituted the score changed to 3-2 in favor of Barcelona. I wonder if this is a pattern or a coincidence? I didn't watch the game, but judging by the fact that it was an early substitution, Rashford played very poorly.
It's clear that Barcelona desperately needs a leader in the back line after Martinez departure. Araujo actually has the criteria when it comes to his physique and posture, but I don't see any improvement in his performance at all. Although Barcelona managed to secure a dramatic victory, Levante two goals should serve as a reminder for Hansi Flick to pay more attention to the strength of his backline.
I also see Barcelona players who should have played in the second half or as substitutes, such as Rashford and Casado. Hansi Flick should return Raphinha to his natural position and find an ideal partner for Pedri. If the match results are in their favor, Hansi Flick can make tactical changes in the second half to secure the victory.
