When it comes to the Atalanta - Napoli game it is a matchup between two very close teams. Bookmakers are thinking the same as well by giving nearly the same odds to these teams for the win. It would be a huge risk to bet on a side here. Because it is open for every kind of result. These teams have nearly the same statistics in the standings at the same time.
Napoli are a really solid scorer team in away games so far. Maybe this could help the game become more delightful to watch. If I decide to bet on this game my choice would probably be both teams to score. I don't expect the opposite from two very productive teams here.

Difficult to predict, Atalanta and Napoli both have a chance to win. The reason is that the points gained in the current standings are not too far, yeah their performance is not much different in the last five of matches, also based on head to head in the last five of matches it is not convincing if bet on Atalanta or Napoli.
But seems like Osimhen can comeback to play for Napoli in the match against Atalanta, there are several rumors which say Osimhen has recovered. If Napoli goal machine can play then there is a higher chance for Napoli got winning, but that is if Osimhen has recovered 100%.
If Osimhen will return to play i think this is a good news for Napoli because at least with Osimhen their chances to win the match is quite bigger when they playing without him and actually Atalanta is not strong opponent for Napoli because during this season Atalanta has several times to lose against tough teams just like Inter Milan or Fiorentina so if Napoli can able to performing well then beat Atalanta isn't hard for them
But the most problem is Napoli will play with their new manager Walter Mazzarri so i think all of the players will be required to adapt with Mazzarri strategy so it won't be easy for them to beat Atalanta however i found interesting fact for this match because for betting options the bookmakers provided equal odds for both teams @2.60 which mean this is hard match for them
