Barcelona must maintain their consistency to maintain chances, this season's Europa League is mostly filled with strong teams, they can make it difficult for Barcelona especially when Barcelona is traumatized when dealing with strong teams. This season Barcelona have been beaten by Real Madrid, Bayern Munich and Inter Milan.
Barcelona must not repeat the mistakes that have been made in the Champions League, Xavi must take advantage of his second chance to win the title this season. The cohesiveness of players must always be maintained, the defense line is the center of attention. Barcelona very often concedes more than two goals when playing against strong teams. Xavi must be able to form a more developed Barcelona performance to go further in the Europa League.
Their defense is still in the spotlight because they failed to perform satisfactorily when they had to face a team that had the same strength as them. This is a job that Xavi Hernandez has not been able to finish so far. I think he has to rethink about signing players to correct their weaknesses in this upcoming transfer window. On the other hand, the Barcelona defense must be able to improve themselves if they do not want to lose their position because they do not perform well and satisfactorily.
