Barcelona clearly doesn't want their struggle to end here, they want to prove that their potential is still good to beat Napoli. As we know, Napoli is currently in an unstable condition in the league, so it provides a good opportunity for Barcelona. Whatever Barcelona does this time makes its fans very happy because it has given them confidence that Barcelona is still a strong team even though they are struggling. I think in La Liga I doubt that Barcelona could be in first place by only winning 3 matches if it wasn't accompanied by Madrid's defeat because Barcelona is already quite far behind.
Barcelona managed to win the second leg match against Napoli with a score of 3-1 and I think that is very normal and cannot be a benchmark so we cannot take this too seriously because Napoli is a team that is quite down this season so it looks easy for Barcelona.
It must be said that Barcelona's performance has improved in the last few matches, but to be able to catch Real Madrid at the top of the standings, I think it is very difficult, although mathematically it is still possible, but it is impossible for Barcelona to continue to face Real Madrid, which currently has strong strength and will fall in several matches.
