I think Atalanta is far better in all aspects compared to the Milan atm. I do like how man on man's marking strategy by Gasperini. It's always doing very well in the big match, and i expect him to do that again soon. They get 2.06 for a home game, that's very tempting odds, but the gap to ward Milan is not that big.
Of course Atalanta clearly is a better team than AC Milan this season and the statistics authoritatively backs that claim. The 2:06 odd for AC Milan to win at home should tell you that bookmakers are doubting their abilities which is why they're backing the home team to win the game. No matter how tempting the odds for AC Milan to win are, I'll never stake my hard earned money on the AC Milan to win at Atalanta.
No offense, statistically their position in current matches, Atalanta are definitely much more favored. Unless during the course of the match, there are some things outside the expected line that can make the situation turn around and Atalanta cannot be optimal. Either way, even though Atalanta is much better, they still have to be vigilant, because basically Milan is not a weak team, it's just that they are often inconsistent and have worse performance. However, I saw their match in the Copa Italia, they were quite ambitious and made the best performance, until they could beat their opponent, Sassuolo with a score of 6-1, but of course, Atalanta is different.
