Girona has managed to be strong and consistent in La Liga this season, and it was only Real Madrid that defeated Girona yet, so there is nothing to be worried about Girona's consistency this season. Real Madrid is only leading Girona by 2 points, and if Real Madrid fails to win their matches, I think Girona will overtake them at the top of the La Liga table.
Real Madrid's have draw their last match against Atletico Madrid. They refused to acquire the three points, given that Real Madrid scored one goal in the first half and Atletico Madrid equalized in stoppage time, I didn't think Real Madrid will win the La Liga tittle so easy this season. Real Madrid and Girona are separated by two points. Girona will overtake Real Madrid for the top of the league, if they continue to draw or losing games. This season, Girona performance has surprised everyone in La Liga and only lost to Real Madrid. They have defeated many major teams this season.
Barcelona got another win which is against Alaves this time. The final score was also quite decent to improve the morale of the players. But the weakness in defense is still clearly seen. 
I don't feel like it will ever get better than this during the rest of the season either. As long as it is enough to keep them in top four it would still be some consolation for Barcelona. I'm mentioning this because Athletic Bilbao aren't far away from top four now. It would be like a nightmare for Barcelona if they don't even manage to join the Champions League. I hope things don't come to that point.

Barcelona's best option at the moment is to qualify for the next Champions League if they are unable to win any trophies this season. It would be very disappointing if they fail to qualify for the next Champions League. Barcelona's 3-1 victory over Alaves is an important achievement for the team. If they keep up this level of play, they shouldn't concede many goals. Barcelona has moved up to third place with 50 points; however, with Athletic Club and Atletico Madrid behind them, they will need to play stronger and more defensively to keep their hopes of finishing in the top four.
