Thats game for Barcelona was very important against Cadiz last night and they got the three points out of it which can be useful for them too because in another game Real Madrid on the game agist Ossasona with a 2-0 result and got three points so if Barcelona couldn't win the game they could decrease the space with Radl Madrid and Carlo Ancelotti could definitely use this chance to but for now they need 8 points to reach Barcelona in the league which is a lot.
Three points that prevent Real Madrid from breathing down their necks, they are super important points especially from a psychological point of view
If this continues, Barcelona can manage to win La Liga.
Barcelona doesn't have to win by a landslide, they just need to win every game even with a narrow score, that will make them comfortable in their current position. Barcelona managed to take advantage of Real Madrid's decline, so they have an 8 point advantage now. Things like this are what they have to take advantage of, yes they have to take advantage of any results that are not optimal from their eternal competitors.
