Romelu Lukaku bagged a brace following Lautaro Martinez’s strike and an unfortunate Riccardo Improta own goal.
Inter absolutely dominated the match at San Siro, even more so than the 5-2 victory over Benevento at the start of the season.
They were given a gift of an opener, though, as Improta accidentally deflected Christian Eriksen’s free kick into the far top corner.
Lautaro Martinez then ended his goal drought by making the most of a lucky ricochet, before pouncing on an awful Lorenzo Montipò pass to set up Lukaku.
The Belgian completed the rout by springing the offside trap on an Alexis Sanchez assist.
