After goalkeeper Mike Maignan was dismissed in the eighth minute of extra time, Milan ran out of replacements, so Giroud donned the gloves. In the 87th minute, Christian Pulisic scored the game's lone goal. In the 113rd minute, Genoa's custodian Josep Martinez received a second caution. Martinez, who had already received a yellow card for wasting time in the 86th minute when there was no goal, caught Yunus Musah with a hasty challenge after coming up for a late offensive corner.
The video assistant referee determined that Maignan had caught Caleb Ekuban outside of the box and gave him a straight red. As a result, Maignan would be absent from Milan's subsequent encounter against Juventus. Giroud, a Frenchman, came to the rescue when Milan needed a hero, even making a valiant last-second stop to help his team go two points clear at the top of Serie A, ahead of rival Inter Milan in second.
