Honestly, it is quite doubtful to expect Girona and Bologna to perform well in UCL. You must be aware that these teams have changed, they are no longer the same as the previous season. Some of the key players of Girona have moved to other teams, even their captain left the club. It will be very difficult to maintain the performance if some of key players are no longer in the squad. Meanwhile Bologna has changed their coach because Motta moved to Juventus. I am sure the performance of Bologna won't be the same as the previous season under the new coach. Even in domestic competitions, these teams may be difficult to maintain their performance. It will be harder to play in UCL, I am a bit worried with the performance of these teams in UCL. If they can't play optimally, I think they can't reach the knock-out stage.
Anything is conceivable; they can give their all and perform well in the UCL since football is unpredictable. Last season, Girona did well in the laliga and challenged many clubs in the league, so I don't see why they won't perform in the Champions League next season. Girona will push Barcelona and strive to win the league if Real Madrid does not stop them, and I am confident they will do all necessary to win. The Champions League is a difficult competition in which you must find better, more talented players to fight with Real Madrid and Manchester City, they are the best clubs in the competition every season.
If Girona performs as well as they did last season, they will most likely win the competitions, but it will not be easy for them because other teams have more essential players than them in the contests. The following season's Champions League will be difficult for any club because the system has changed, and each club must sign players who can help the club win the trophy. Bologna played well last season as well, but I see Girona are better than them in terms of performance on the pitch. In my opinion, Girona and Bologna if they don't get the opportunity next season and qualify to round 16 of of the UCL they will qualify to the europa league, let see how the ucl we go next season and know who will get the chance and win the trophy.
Performing well in the domestic league does not guarantee that you will also be able to perform well in the Champions League because the atmosphere of the UCL is very different from the domestic league. In the Champions League, you have to be able to perform consistently if you want to survive, unlike the domestic league which takes into account points to become champions.
I am more confident in Leverkusen ability than Girona, since under the guidance of Xabi Alonso, Leverkusen has turned into a club to be wary of. Girona ability is not yet able to match Leverkusen strength, if these two teams meet, it is clear that Leverkusen will win the match. Although surprises can happen in football, I am not sure Girona can do it because they will have a hard time competing with other strong teams.
You are right. The champions league is another competition that you cannot enter with the usual league; there are many clubs in the competitions that you do not play with, except in the champions league. with the way Leverkusen performed last season, winning the league and challenging Dortmund and Bayern Munich were unquestionably successful last season, and they will undoubtedly compete in the UEFA Champions League, but you can't predict whether they will win the trophy or not because the season hasn't even begun, and you can't say who will win the trophy. Many people are stating Real Madrid are the primary club that will win the title since mbappe has arrived to the club and they are more stronger and can challenge any club in the champions league. any club that comes to ucl mean they are good that is why they get the chance and play in the competition. so anyone have the chance of winning the trophy since the season as not started yet we will see how everyone club will perform and see who will get the chance but am sure levenkusen who try there best and move to round 16 in the champions league next season.
