Romelu Lukaku marked his first appearance in an Inter shirt by scoring four times in his new side's emphatic win against Virtus Bergamo.
The forward wasn't ready for Saturday's friendly trip to Valencia, left out of Antonio Conte's matchday squad entirely for a game which Inter eventually won on penalties after a 1-1 draw.
However, he was part of a much-changed side that took to the field for a low-intensity encounter against Serie D minnows Bergamo on Sunday.
Handed the number nine jersey, previously warn by Mauro Icardi, Lukaku made a good first impression as he netted half of Inter's goals in an 8-0 thrashing.
Matias Vecino and Sebastiano Esposito, two other players in need of minutes, scored braces to complete the rout.
