Considering that, from the bookmakers' point of view, Barcelona has approximately a 30% chance of losing points, based on your assessment, you can safely bet on Barcelona. But I think it's too risky. Even though Barcelona wins tough games (eg against Atlético Madrid) they have too many tough games - even against outsiders. Girona looks like a more “vigorous” team and Girona’s goal difference is at least a little better than Barcelona’s. I see no reason why Girona cannot put up a serious fight in this game or even win it.
I think this betting is very difficult, because according to predictions the chance of winning could potentially be achieved by Barcelona but for some reason right now I prefer to bet on Girona winning because in essence I see Girona's performance is very good, and according to the standings alone because Girona is in the standings 2nd place he has 38 points but in the match when Girona faced Bilbao I saw that Girona's performance was slightly reduced because the result was a 1-1 draw but indeed Barcelona is a strong team and the proof is that when they faced Bilbao Barcelona won the match with a score of 1-0 so indeed Barcelona too has privileges that Girona doesn't have, but when facing Rayo Barcelona drew with a score of 1-1 but when Girona faced Rayo Girona won the match with a score of 1-2 yes this is a difficult situation to predict who will win later, it looks like we have to see Girona's performance tomorrow in the match against Orihuela in the Copa Del Rey league so that we can learn more and measure the extent of Girona's strength.
Personally, I decided to skip this game completely. Neither BTTS nor Total attracts me. I really have no idea how this game will go. And it’s not about Girona, if there was a game between Girona and the same team as Girona, then I would be sure that the total would be more than 2.5 and BTTS, even with odds of 1.5, would be profitable. The problem is in Barcelona. Maybe they will play the bus, maybe they will have problems converting chances. The score can be either 1-0, 0-0, 0-1, or 3-2. I won't risk it here.
