After 15 minutes played, Milan had already managed to get a 2-0 lead.
After 27 minutes, a mistake by the home side's left defense allowed Gianluigi Donnarumma to get through. He outclassed the home side's keeper, adding another goal for the visitors.
But when Luis Alberto got a nod on the return, Donnarumma did not have time and the ball went into goal to 1-2.
With 59 minutes played, the Immobile coach decided a substitution may help turn the game around.
He got the ball just outside the goal area line and was able to put it on half volley to 2-2.
But just like against Parma two weeks ago, Theo Hernandez saved his Milan in overtime.
In the 92nd minute he put the final score 3-2 and Milan is again in the league lead in Serie A.
Zlatan Ibrahimovic is still injured and is expected to make a comeback only in January.
