I, on the other hand, think that Atalanta are a rocky team and that they will give their opponents a lot of problems, let's say that they are not the last to arrive, they won the Europa League playing fantastic football and therefore for this very reason I say that they could do better even than liverpool!
The last meeting between the two could be a reference where Liverpool had to suffer such a humiliating defeat in the Europa League. But maybe this is different because now talking about the Champions League competition and its prestige also looks quite different. Atalanta may not be a strong club in the Champions League because talking about now and experience but that doesn't mean they are easy to beat. If Liverpool don't prepare everything well then it is feared that they will repeat the defeat like in the Europa League.
For this season I am optimistic that Liverpool can beat Atalanta in the Champions League because I see Liverpool being much more consistent now. If you look at the quality of the players then it can be concluded that Liverpool are superior in many ways to Atalanta, so that moment must really be utilized by them.
