Ciro Immobile scored an impressive hat-trick as Lazio thrashed big-spending AC Milan by 4-1 in Serie A.
Italy international Immobile opened the scoring from the penalty spot, before volleying in a superb effort for his second past Gianluigi Donnarumma before half time and completed his triple by converting from close range just three minutes after.
Luis Alberto scuffed home a fourth and Riccardo Montolivo slotted in a consolation for Milan, although Lazio — who lost Marco Parolo to a stoppage-time red card — never looked like relinquishing their vice grip on the full three points.
The win meant that Simone Inzaghi’s men remain unbeaten this season, although result raises questions for AC Milan who, after a takeover by Chinese Investors had spent more than €200 million ahead of the campaign.
A tactical overhaul from Milan boss Vincenzo Montella did allow Riccardo Montolivo to pull his team goal back from distance before the hour, but not even the late dismissal of Parolo could help them save face.
Lazio, on the other hand, looked comfortable and never out of grips in a performance that underlined their ability to challenge the top of the table this season.
Before the game started, there was a delay by an hour after flash floods in Rome, with roads were inundated following heavy rainfall in the city and Metro lines in the Italian capital closed down.
The Stadio Olimpico pitch itself was not an issue as the surface had been covered by sheets on Saturday which prevented any waterlogging, but there were large banks of empty seats inside the stadium as supporters struggled to get to the game as a result of the floods.
