Lazio defeated AC Milan 2-1 on Sunday at the San Siro thanks to a penalty in extra time. The home team had equalised despite being reduced to ten men and had to deal with an angry crowd that was protesting the club's owners. After AS Roma defeated Como 2-1 earlier on Sunday, Milan dropped to ninth position in the rankings with 41 points, while Lazio moved up to fourth place with 50 points, one point ahead of Juventus, who will visit Hellas Verona on Monday.

The Milan Curva Sud ultras left their sector unfilled until the fifteenth minute of the game in protest against owner Gerry Cardinale, the manager, and the players after a dismal season, creating a muted environment. Mike Maignan was fast off his line and spread himself well to save with his foot after Nicolo Rovella sent Boulaye Dia through one-on-one with the keeper.
