Barcelona have not been able to score in the last two matches, when they were defeated by Real Madrid 0-4 in the semifinals of the Copa del Rey and the last match when they were held to a 0-0 draw by Girona in La Liga, this is a warning for Barcelona striker even though their position in the standings is still superior 13 points from Real Madrid.
Barcelona don't loss any points more in La Liga if want quickly winning La Liga or their opportunity take by Real Madrid on 2nd position, next games against Getafe should winning with bigger score before have difficult games against Atletico Madrid up coming two weeks later. I sure if Barcelona have consistent performance for several matches later still have chance for La Liga tittle in this season.
Although currently Barcelona's position is quite safe. but yeah it's true that Barcelona should be able to win the next few matches. so that they can celebrate their superiority at the top of the standings earlier. The next match against Getafe can indeed be an opportunity for Barcelona to get full points. Because next week the match against Atletico Madrid will be more difficult. although I'm sure Barcelona can also win against Atletico Madrid. but the point is Barcelona should not feel calm because of the points advantage they currently have. I hope they keep playing at their best until the end of the season.
