This match is equally important for Barcelona and Girona. But I think it could be a draw. Both teams have lost once each this season. It's hard to say who will win, but it will be a very interesting match. Girona should not be underestimated.
This match will be a test about the readiness of Girona to grab the title this season. Girona will have hard time trying to defeat Barcelona in their home. Bookies are backing up Barcelona much to win that game. The comparison between the names and skills of players are way in favour of Barcelona side. Girona's players have to prove themselves in this match and make everyone respect them for what they did so far 
Nobody will dare to underestimate Girona, look at their impressive away games in this season.
7 unbeaten away games, 6 winning streaks and always score when away.
If Girona able to get 1 or even 3 points from this match then they have the rights to dream about the Champions League next year.
