Atalanta can do well, but let's remember that Inter and Napoli travel at very high speed, and have much more easy matches, Inter is definitely the favorite for this championship, their matches are much easier, I don't think Atalanta can overcome the big teams that are in command there
But if you look at their statistics in Serie A, Atalanta actually has a big chance to become champions this season. Of course big teams like Inter Milan and Napoli are strong teams and hard to beat. However, I think Atalanta is currently on the same level as them. Atalanta has good goal productivity and even 2 of their players are among the top scorers in Serie A. I think Atalanta can even beat Inter Milan next week. They play as hosts and that will boost their confidence. I favor Atalanta to win that match.
