If it was Girona last season I could still hope more for them but for Girona now actually Barcelona's victory for me is not too much of a surprise because after all we must be aware that for Girona this season the performance although still a little better but quite far when compared to last season.
But it is indeed very good for Barcelona where they are quite capable of remaining consistent in their conditions which are only given a short break but their dominance still does not slacken.
Currently, it is certain that they are 3 points ahead of Madrid in the remaining matches that are getting thinner. This is an advantage for Barcelona but not for Madrid because they must continue to be consistent while hoping that Barcelona will have problems that allow them to get closer so that the competition continues to occur with tight points.
I agree with you, that this season Girona's performance cannot be compared to its performance in the previous season. Because it cannot be denied that in the previous season Girona's performance was indeed great and was able to become a tough competitor for Barcelona and Real Madrid. But this season Girona's performance has slowly declined, so it is only natural that in the match against Barcelona Girona suffered a fairly crushing defeat. Because Girona's current performance is indeed not comparable to Barcelona's very good performance. Therefore, I personally am not surprised if Barcelona wins this match without any significant difficulty.
In addition, Barcelona is currently 3 points ahead of Real Madrid, I think this can be said to be quite safe for Barcelona. Because as we know Barcelona's current performance is very good and it can be said that the remaining matches that Barcelona will face in La Liga are likely to be won by Barcelona. So with this I am very sure that Barcelona's potential to become champions in La Liga this season is very large.

In addition, in the upcoming match Barcelona has a match schedule against Atletico Madrid in the second leg of the Copa del Rey semifinals. I think this match will be really exciting and in this match I will support Barcelona to win.
