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.
To bet on 1x2 Atalanta which is very dencent consider we can double our money. 2.5 goals are even offered less than 1x2 Atalanta, but as you said, it's likely to happen. I personally wanna choose a direct bet to Atalanta instead of consider other options.
I agree with this because looking at what was shown on the field in the last few matches, especially if you look at the attacking schemes and productivity they have, it is clear that Atalanta currently has an advantage over Milan.
Not that Milan are a bad club but if we look at what they have always shown this season I think we realize that Milan's schemes are too monotonous and do not want to take risks in matches and prefer to play passively in order to get at least 1 point which makes Milan in trouble like now.
I think doing at 1x2 for Atalanta is not a problem especially with the performance they are showing like now but even so I think for betting it will still be worth it for both teams to score because even though Milan is always with its boring game but counterattacks with their long passes are always on points and can be used as a troublesome weapon in a match.
