Atalanta will be hard to play at UCL for this season. But, I see them still good on domestic league. In serie-A, they can beat Roma, draw with Fiorentina and become on 3rd place until match day 6, I think Atalanta would be better for the next season in UCL if they are qualified again. But, they must keep their best performance until last season on serie-a. So, for this season, I think Atalanta doesn't have a chance to be on the next round. 9 points to save their chance in the next round, Antalanta must keep winning for 3 matches.
The draw for Napoli was the frustrating for me. Not only I lose my bet for them, the 4th team on current Serie A drew to the 7th team of Belgian league. The KRC Genk have no good record of playing in Champions league but when they do, they have a good record of playing a draw with good teams.
