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.
Girona was initially doing well earlier last season but ever since they lost form, and Real Madrid won the title, their winning spirit declined drastically, and they have been struggling since then. Girona is still a developing club so nothing much is expected from them in the Champions league so let them just play all their matches and return home with pride because it is not easy to have a Champions league experience for the first time in the club's history. The only game among the three teams you mentioned that they can perform well a bit will be against AC Milan but for Arsenal and Liverpool, they can't really compete with both teams because the two teams are far stronger than Girona in every angle.
We were very surprised by Girona's performance last season. Girona had been able to perform consistently well since the beginning of the season. And Girona had been at the top of the La Liga table for a long time. But the team could not maintain consistency until the end. Girona was in third place in La Liga at the end of the season.
Girona's performance has been weak since the beginning of this season. Girona is in eighth place in the points table. Girona has won only 6 matches out of 15 matches. At the same time, Girona has lost four matches in the Champions League. Girona's overall performance is very weak. With such a weak performance, it is impossible to get points against Liverpool.
