the Milan derby is always a very particular match, it is not always won by the strongest and as you have already said, Milan has won the last 2. I think that Inzaghi has made enough turnover to be able to manage this match at best but I cannot tell you if he will win or if Milan will be the winner once again. the fact is that to keep up with Napoli, Inter is forced to win
That's the tricky subject of it, and I am pretty sure that is what makes the betting a lot harder too. Because it's a derby, teams play differently on these games and that means whoever is doing better that season, isn't going to end up winning at all times.
It is not just about this san siro derby, it's about all derbies in the world, I have seen teams go down in division and still beat the team above their division just because it was a derby and they care a lot more. I am not sure what causes that, and what kind of different mindset that we get, but at the end of the day we are not going to end up with a different result. Which is why I am pretty sure that this game could be anyone's win, and betting is so difficult.
