This is the odds for the Derby della Madonnina. Would you trust Milan against Inter now? I wouldn't honestly. Instead, I would go for my mostly preferred betting option recently, BTTS & over 2.5 goals @2.10. 
I wanted to believe that Milan is going to win against Inter on the fact that they will be playing at their home but like you said, judging by their performance in recent matches, I am having a little doubt and my prediction is also Over 2.5. Although, I will also bet on home win.
