As you said, they both have what it takes to win that game, which I think makes it a very interesting game for sure. I don't think it would turn into a one sided match where one of them takes a lead of two goals or more. I would rather expect a close back and forth between them and both have some great defensive power. AC Milan has quite a high speed attack now and Inter Milan has been very effective with their chances in the last few months. I think almost all outcomes are equally like and it is not really a perfect home game for the home team either given that it is the derby between the two teams.
The statistics of their last 3 meetings Inter have the upper hand as all three have been won by Inter but in this case the biggest score is 2-0 so I agree with what you say where this match will not have a big enough goal difference especially if you see the performance of both teams at the beginning of this season.
Two goals at the most but I'm not sure about that because it could be a narrow win for either club and it could even be a draw.
The odds are quite attractive but looking at the h2h advantage and Inter playing
