Inter came via their 1st Derby della Madonnina below Antonio Conte with flying colours as they piled stress on underfire AC Milan boss Marco Giampaolo.
The star of the show was not Romelu Lukaku, nor Lautaro Martinez, but in reality a quiet Uruguayan that created the Milan attack appear impotent. His name is Diego Godin.
Milan surprisingly began Rafael Leao on Saturday evening and when the Brazilian was the most lively of the Rossoneri frontline, but he was expertly marshalled by Godin.
Adding encounter, leadership and a canny capacity to study the game to an currently strong defence, the 33-year-old has slotted in brilliantly on the ideal side of the back 3, which is an altogether unfamiliar position.
