This is true. The season is still long, there are still about 12 matches to play and a lot can happen in 12 matches. Barcelona still have to play Atletico, Madrid and Bilbao, all these are very tough matches at a crucial point of the season, but with how Barcelona have been playing, I think they will hold on till the end.
This season Barcelona are trying to keep their performances very strong so that they can able to win against any of their opponents, because it seems like Barcelona don’t want anything that can make them drop anymore, and that’s why they look very serious whenever they get a match these days; but don’t I know they have that capacity to keep their performance in that way.
Because they're only ahead of Atlético with one point and even Real Madrid is also trying to maintain their consistency so that they also move up to the top of the standings, and the only thing that can save Barcelona is those remaining matches that still have to be played.
