Serie A round-up: Sassuolo's 4-3 Milan win is biggest in top flight
Domenico Berardi scored four goals as Sassuolo stunned Milan 4-3 on Sunday evening. Goals from Robinho and Mario Balotelli had given Milan a 2-0 lead after 13 minutes before Berardi stole the show at the Città del Tricolore stadium.
The 19-year-old, who is on loan from Juventus, scored a hat-trick before the break and added his fourth two minutes into the second half.
Riccardo Montolivo gave Milan a lifeline four minutes from time but Sassuolo held on for their biggest win yet in their maiden campaign in Italy's top flight.
The defeat was Milan's seventh of the campaign and dropped them to 11th place, 30 points behind the Serie A leaders, Juventus, at the halfway stage.
Juve came from behind at Cagliari to claim their 11th consecutive league triumph. Mauricio Pinilla put Cagliari ahead in the 21st minute before Fernando Llorente equalised on the half-hour.
Claudio Marchisio gave Juve their first lead in the 73rd minute before the Spanish international Llorente scored his second three minutes later. Stephan Lichtsteiner notched the Turin club's fourth goal in the 80th minute for a 4-1 victory. Juve are eight points clear of Roma at the top of the standings.
Roma, coming off their first defeat in Serie A – a 3-0 defeat at Juve – romped to a 4-0 triumph over Genoa.
Goals from Alessandro Florenzi, Francesco Totti and Maicon handed Roma a 3-0 half-time lead. Mehdi Benatia wrapped up all three points for the Romans in the 52nd minute. Genoa finished the game with 10 men after Francesco Matuzalem was shown a red card on the hour.
Dries Mertens was again on target as Napoli won 3-0 at Hellas Verona.
The Belgian winger, who struck twice against Sampdoria last weekend, put Napoli on their way in the 27th minute and the game was put beyond Hellas's reach with Lorenzo Insigne and Blerim Dzemaili scoring midway through the second half.
Fiorentina lost ground on Napoli and the last Champions League qualifying spot as they were held to a goalless draw at Torino. The absence of the injured Giuseppe Rossi hurt Fiorentina, who failed to threaten the home side. Rossi, Serie A's top scorer with 14 goals, is out of action with a right knee injury. The outcome dropped the Viola five points behind Napoli.
Atalanta claimed all three points for the first time in two months with a 2-1 triumph over Catania. The outcome lifted the Bergamaschi to 12th and kept the bottom side Catania winless on the road this season.
