Barcelona won the La Liga last season but with the way they are performing this season, nothing good can be expected from them this season as well. They lack a great finisher and have considerable weaknesses in their defense as well. They enter the field with the same strategy to catch every match. To do well in major tournaments, Barcelona must work on their weaknesses as well as change their tactics, only then will they be able to do well. Barcelona is a big name for those of us who follow La Liga regularly and we always have a bit higher expectations for Barcelona but currently Barcelona are not able to perform to our expectations at all.
I agree with you, Barcelona won the last season La liga beating even stronger team's like Real Madrid to top the league, which was a good performance and to keep to that trends, there is a need to further ride on the record and performance better than the last season, but truly this season, Barcelona have not really shown any level pf consistency in their performance and in the last few matches, it has become clear that the club is struggling in this season much more than the last season when their we're able to win the league title.
Most of the time, is either they play draw game or even lose to their opponents in this season.
Barcelona's performance in the previous season in La Liga was very consistent and they won the title. The main reason for this was that in the previous season the focus of the Barcelona team was only on La Liga matches. We have not seen Barcelona players play well in the Champions League and Europa League. They only focused on La Liga so the team was able to win the title by consistently performing well.
This season's scenario is different. Barcelona also wants to play well in the Champions League. This is why Barcelona has fallen behind in the title race by performing poorly in several matches in La Liga. Barcelona's performance is also somewhat erratic now due to the busy schedule. But I would say Barcelona have the potential to do well in the Champions League.
