If it turns out Atlanta win Liverpool I may not be very surprised but then I will believe it's probably a lucky day for Atlanta, in champions league it's usually a very different spirit altogether because they know how prestigious the trophy is, Liverpool is a much very and experienced team in the champions league than Atlanta and this has been the reason Liverpool has been seen as the favourite. Atlanta have a sound confidence currently dues to the fact that they win the Europa and even this season they are starting on a good start but then champions league is really different.
The incident occurred last season, it must be admitted, Atalanta performed very well last season especially when playing in the Europa League. I don't think the victory over Liverpool was just luck because in the final they also managed to beat Leverkusen and became the only team that was able to beat Xabi Alonso's team.
Now that we have entered a new season, usually the team will experience a decline in performance or vice versa, but what is happening to Atalanta now is no longer the same as last season, their performance is starting to decline and it is predicted that they will have difficulties in the Champions League. Although Atalanta came to the Champions League as winners of the Europa League last season, this achievement was not enough to compete with other strong teams, especially since their experience in this major competition is still very minimal.
Atalanta was in a good form last season and that was why they were able to beat Liverpool and Leverkusen in finals to win the cup. The club sold some of their players and that affected the team performance. It is a shock to see how a strong team became so weak without playing matches. It seems that Italy teams can be very strong today and become vegetables tomorrow. This was what happened to Napoli too last season.
