this season it seems Barcelona is just much interested in winning the laliga. Manchester United have been well in the Europa league, they would like to still maintain their consistency.
Manchester United have been in the Europa League from the start, while Barcelona they haven't even play a one match in the Europa League. In my opinion, to assess the consistency of the two in the Europa League, at least we need to see Barcelona's performance in the Europa League first, it looks more balanced as a reference.
