The Rossoneri avenged a 1-0 loss at the hands of the same opponents on Sept. 13, 2015, extending their unbeaten run in all competitions to six games in the process.
A header from Alex broke the deadlock after 35 minutes, but the defender looked to have turned from hero to villain when he gave away a penalty in the second half.
However, forward Mauro Icardi—who had started the game on the bench—saw his spot-kick kept out by a post. Just three minutes later, AC Milan doubled their lead when striker Carlos Bacca converted M’Baye Niang's cross.
Niang turned from provider to scorer for the game's third goal, the forward finding the net at the second attempt after Inter goalkeeper Samir Handanovic had saved his initial effort.
