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.
Didn’t come across the next three fixtures all yet, I only know of their next one against Liverpool who happen to be the best in the competition now. With this fixture, it’s almost to conclude that Girona will be leaving the champions league from this first round and won’t make it to the next round of the competition again. Girona performance in the champions league is not even looking good and their position is not even considering them for even a playoff in this competition. Arsenal, Liverpool and AC Milan are big teams in the champions league and their performance are far much better than what we see from Girona, it’s likely this is the end of their path in the champions league this season and will just try to finish in the top four this season to get a chance for next season again.
