Yes I agree with your opinion.Barcelona is trying to play more focused games now.Because in UEFA Europa League Barcelona played bad game in several matches due to which now they want to correct those mistakes.What I have seen is that Barcelona goalkeeper has a lot. By performing well, due to which Barcelona is known as such a strong team.
Maybe you mean playing badly in the Champions League, not in the Europa League, because Barcelona, who are already in the Europa League now, is due to not qualifying for the Champions League group phase, so they have to be in the Europa League play-off round. And yes Barcelona will try to improve everything in the Europa League as well as in the domestic league as well as has been seen from the results in several matches there (La Liga).
