Serie A round-up: Cristiano Ronaldo scored as Juventus beat Frosinone
Last Updated: 23/09/18 10:30pm
Cristiano Ronaldo bounced back from his red card against Valencia by opening the scoring in Juventus' 2-0 win over Frosinone.
Ronaldo left the pitch in tears in midweek after controversially being sent off for the first time in the Champions League for clashing with Jeison Murillo at the Mestalla.
He put that setback behind him to fire Juventus in front with nine minutes remaining against Frosinone before Federico Bernardeschi sealed the victory in stoppage time.
Bologna's first goal of the season was worth the wait, and led to a surprise victory as Filippo Inzaghi's team upset Roma 2-0.
Robin Olsen only flapped at Sebastien De Maio's cross and the ball came through to Federico Mattiello near the byline. He cut back, before curling a finish into the far side of the net.
Federico Santander raced from inside his own half to collect Diego Falcinelli's pass and finish off a swift counter-attack.
Roma have not won since the opening day of the season and lost 3-0 at Real Madrid on Wednesday.
Lorenzo Insigne scored twice to help Napoli win 3-1 at Torino in a dominant performance from last season's runners-up.
Torino gifted Insigne the first goal with less than four minutes on the clock. Emiliano Moretti attempted to clear Sebastiano Luperto's cross but it came off Torino teammate Nicolas N'Koulou and straight into the path of Insigne, who drove it in under the crossbar.
Simone Verdi doubled Napoli's lead in the 20th minute with his first goal since joining from Bologna in the summer. The Italy forward started the move in midfield before passing to Dries Mertens on the left and racing into the area to fire in the return pass.
Torino got back into the game when Andrea Belotti converted a penalty early in the second half after Alejandro Berenguer had been brought down by Luperto.
However, the hosts gifted Napoli another easy goal shortly afterwards. Armando Izzo lost possession in midfield to Marek Hamsik, who picked out Jose Callejon. The Spaniard's shot came off the post but Inisgne was on hand to tap in the rebound.
It was Insigne's third goal in two league matches, following a slow start to the season.
Giacomo Bonaventura scored against his old club but AC Milan was held 2-2 by Atalanta following a stoppage-time equaliser from Emiliano Rigoni.
Gonzalo Higuain had volleyed in the opener after 90 seconds for Milan before Papu Gomez levelled early in the second half.
Bonaventura, who also had a goal disallowed on video review, and Higuain both hit the post.
Elsewhere, Lazio picked up their fourth victory in all competitions with a 4-1 win over Genoa, while Udinese won 2-0 at Chievo Verona.
