Lautaro Martinez had handed Inter the lead in the 13th minute before Thomas Henry restored parity by scoring the equaliser for Veron in the 74th minute. Frattesi scored the winning goal in the stoppage time to seal an important win for the Serie A leaders.
After scoring the late winner, the Italy international ran towards the San Siro crown in ecstasy and celebrated with the fans. As the player leaped on top of a yellow fence near the gallery, his team-mates accidentally pulled down his shorts which exposed his backside.
