ROME (AP) — Napoli and Roma remained perfect atop Serie A with key wins, Inter Milan thrashed Sassuolo 7-0, and two-time defending champion Juventus struggled at times before edging Hellas Verona 2-1 in a busy Sunday of the Italian league.
Napoli came away from the San Siro with a 2-1 victory over AC Milan with goals from Miguel Britos and Gonzalo Higuain, while Mario Balotelli failed to convert a penalty kick for the first time in his career.
"We worked really well as a squad today and I think that's our strength," new Napoli coach Rafa Benitez said. "We're still starting this job and we allowed a lot defensively tonight but beating a big squad like Milan at the San Siro is important."
Roma beat rival Lazio 2-0 in the city derby, with fullback Federico Balzaretti scoring the decisive goal and the Giallorossi's 36-year-old captain Francesco Totti again proving decisive.
In the lunchtime fixture, Diego Milito scored twice on his return from injury as Inter thrashed its recently promoted opponent amid news that Indonesian businessman Erick Thohir is closing in on a takeover of the club.
Juventus came from a goal down in Turin to edge visiting Verona with goals from Carlos Tevez and Fernando Llorente, while Mati Fernandez and Giuseppe Rossi scored as Fiorentina won 2-0 at Atalanta.
Also, it was: Catania 0, Parma 0; and Bologna 1, Torino 2.
Through four rounds, Napoli and Roma are two points ahead of Juventus, Inter and Fiorentina.
In Milan, Britos put Napoli ahead six minutes in with a header following a free kick and Higuain doubled the lead in the 53rd with a long, low shot that Rossoneri goalkeeper Christian Abbiati got a hand on but wasn't able to stop.
Balotelli was 21-for-21 in his professional career from the penalty spot but Napoli goalkeeper Pepe Reina blocked his effort in the 61st after the striker was dragged down by Britos. Balotelli's shot wasn't perfectly placed to the corner and Reina guessed right as he lunged to his right.
"We knew Mario was very strong at the penalty lottery and we were a bit lucky," Reina said.
Balotelli was unfortunate again in the 71st when he hit the crossbar, although he finally found the target in added time with a splendid, curling, long-range effort.
Still, Milan dropped eight points back, and Balotelli picked up his second yellow card after the final whistle, for protests, and will miss the Rossoneri's next match.
In Rome, two days after extending his contract for two more seasons, Totti provided the cross in the 63rd when Balzaretti volleyed in for his first goal in Serie A since April 2011, when he played for Palermo.
Seconds before his goal, Balzaretti hit the post.
Lazio's best chance at the Stadio Olimpico came when the ball bounced just wide off Miroslav Klose's thigh in the 55th. Lazio was reduced to 10 men when Andre Dias was sent off for a last-man foul on Totti in the 82nd.
