Didn't expect that indeed, Barcelona was playing at home against a mediocre team like Girona, but the result was only a draw with a score of 0-0. If the score is 0 for Girona, I think it's natural, because in that match Girona didn't have any shots on target at all, so when Girona couldn't score, that was a natural thing.
But yes, it's different with Barcelona who play their best squad like there is Lewandowski up front and also, Barcelona only focuses on La Liga. Then it is a result with a win that must be obtained and indeed, a result like this does not make Barcelona's position overtaken. But at least, Barcelona must maintain the honor of playing at home to keep getting full points.
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 title in this season.
Barcelona is in the same situation as Arsenal in this season the difference between both is that, while Arsenal has won the last few matches in the premier league with just one draw match, Barcelona on the other hand has been on a steady defeat so is easier for Real Madrid to have a take over of the first spot since Barcelona team have become demotivated since the semi-finals.
This final leg may become the end of Barcelona shinning in this season because the opposition is stronger and better Real Madrid will easily take over the league from Barcelona any moment from now but I am sure that Barcelona will settle for the second spot if they drop from the first spot for whatever reason.
