Girona is 30th in the standings with 3 games left to play and clearly has a chance of less than 5% to enter the play off round. For that reason Girona can only play as hard as possible without taking risks, because the clubs above them will also compete to win the play-off zone. But if Dovbyk is still there, maybe Girona performance will be a little better in the UCL.
Girona has a Champions League remaining against quite tough teams. The 3 teams are Liverpool, Milan, and Arsenal. It will certainly be quite difficult for Girona to at least qualify even through the playoffs.
Girona's performance has declined this season. They performed better last season, but this season they are having problems. 5 matches with 3 points collected, it will be very difficult to be able to fight when seeing their opponents are strong teams.
I don't even expect good performance from Girona in this ongoing Champions League because of the level of their players. All their players are still average with less experience in the Champions League. So, I don't expect them to even qualify for the next round. With their next three matches, it’s really clear they will not qualify because they will find it difficult to win against the three teams you mentioned Arsenal, Liverpool, and AC Milan. At best, they might manage a draw against one of these teams based on their current form. These three teams are seriously in good form. But let's see, as football is full of surprises. Maybe they’ll get lucky and win one or two matches, but I’m not entirely sure it will happen.
Well I feel sorry for Girona because they were unfortunate to be playing in the champions League in a time when the competition has been altered and the group stage settings scrapped, so for teams like Girona whom are playing in this competition for the first time will always have to struggle due to the nature of the tournament and the kind of opponents they would have to face, besides it has been very difficult for them from the beginning and I don't think they would be able to get any impressive result from their remaining games they have to play.
