Girona is a team that is in the middle zone of the standings, but based on the results of away matches so far this season, Girona is in the bottom zone. So, Girona doesn't have good abilities when playing away and what's more, in this match Girona will play away against Barcelona, which in fact this season Barcelona is fairly good for all results in matches in La Liga.
Also, Girona have never managed to beat Barcelona in a La Liga match from the past until now, so it's pretty clear that Barcelona will definitely win. Instead of betting on Girona which has no chance of winning, then I think it would be better for you to bet on Barcelona's win but with quite high money. Or, you can choose other options such as HT/FT wins, Asian Handicap and correct scores etc., because these options can allow you to get pretty good odds too.
Its going to be a difficult match for Barcelona either way. They are without so much key players, Christensen, Frankie, Dembele, Pedri. Barcelona will definitely posses the game as they always do but they will find it difficult to score goals. People blame Lewandoski but I don't think its his fault because almost all the creative players in Barcelona are not available. Barcelona is also eleven points clear at the top so they might not be as motivated as they use to, plus there is the fact that their morale may be down after the Madrid loss. I see the match as a match that will end 1-0 in favor of Barcelona.
