Faltering AC Milan dealt major blow in Serie A title race
Mariano Troilo headed in late on as Parma claimed a 1-0 win over AC Milan, which saw its Serie A title hopes take another hit at San Siro.
Milan was on a 24-game unbeaten streak in the top flight heading into Monday's clash, but with its first loss since the opening weekend, they remain 10 points behind the leader.
Mateo Pellegrino volleyed narrowly wide in the opening two minutes, but Milan was on top from there without creating too many clear-cut opportunities.
Christian Pulisic sent a powerful, tight-angled shot straight at Edoardo Corvi before lifting another effort just over the bar shortly before the break.
Pulisic also saw a low drive cleared off the line by Troilo on the other side of half-time.
Rafael Leao rattled the frame of the goal with a fine volley after meeting Adrien Rabiot's cross, but Parma continued to stand firm.
And that paid off as, in the 80th minute, Troilo rose above his defender to head Emanuele Valeri's corner into the far post. It was originally disallowed for a foul on Mike Maignan, but the decision was overturned after a VAR review, as Lautaro Valenti was deemed not to be impeding the goalkeeper.
