Don't underestimate Atalanta, if you see their path they are a very tough team to face. The match against Real Madrid was mentioned, but just look at how he did in the Europa League.
They weren't all bad opponents and so in my opinion he has the chance to do very well. Of course I don't think he'll reach the semi-finals
Atalanta is a big what if this year.
They lost 3 key players, Scamacca and Salvini for Injuries and Koopmeiners sold to Juventus.
They also changed a lot of less relevants players, so they will probably need some time to start rolling as they usually do.
