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.
