 Abate played as a regularly starting right-back in the 2015–16 season.One notable moment for him occurred on 22 February 2016, when he made an excellent sliding tackle on Lorenzo Insigne on the right wing, preventing him from scoring a second goal in a 1–1 away draw against Napoli.In late March 2017, after initially being sidelined for Milan's following fixtures against Chievo, Juventus, and Genoa, Abate was ruled out for the remainder of the 2016–17 season, due to requiring surgery after suffering "blunt force trauma" to his left eye, after being hit by a ball in the face during a match against Sassuolo on 26 February.
