I would bet Atalanta to win straight away, Atalanta is just too strong in this season. Milan showed if they're getting better, but they didn't win against Juventus and Napoli, so they're still struggle to fight against strong teams.
BTTS is likely to happen, but over 2.5 goals is quite risky, if you check their head to head, the results are mostly 2 goals.
Yesterday, AC Milan thrashed Sassuolo with a 6:1 scoreline in their Coppa Italia game and because of that result, many are now of the opinion that AC Milan can as well get a result against Atalanta when they meet each other in the Italian Serie A this weekend at Gewiss stadium in Bergamo. I know AC Milan have a strong squad that's capable of going to Atalanta and picking maximum three points but considering the performance of Atalanta this season, I think the best AC Milan can get in that game is a draw
Atalanta have been a strong team this season and have not really shown a very big weakness to make any team look down on them that much. AC Milan winning their last game with a very big win margin doesn’t mean they can have a chance against Atalanta. The opponents are different, so they should expect a different challenge in this game. It won’t be an easy game for them to expect an easy outcome from the game when they don’t at least give in their best. AC Milan should expect a more tougher encounter in this match and if they’re lucky to get a draw, then the match will be in their favour, if not, I don’t see them getting an easy win in this game.
