Juve too strong for Genoa

Juventus had to come from behind to defend its lead in the Serie A standings after Ciro Immobile put Genoa in front in the 18th minute.

Emanuele Giaccherini brought the Bianconeri level after an hour, while Mirko Vucinic and Kwadwo Asamoah added a second and a third to make it three wins out of three for Juve.

Napoli also claimed a 3-1 win to maintain its 100 per cent start against Parma.

Walter Mazzarri's side was in control from the moment Edison Cavani netted a third-minute penalty and, with Goran Pandev and Lorenzo Insigne also on target, Marco Parolo's strike was rendered worthless.

Lazio is third after a 3-1 win over Chievo at the Stadio Marcantonio Bentegodi.

Hernanes was the star of the show, scoring twice in either half, while he also set up Miroslav Klose for his strike for Vladimir Petkovic's side.

Sergio Pellissier netted a late penalty for the host.

Sampdoria also boasts three wins from three after a 3-2 triumph at Pescara.

Maxi Lopez gave Samp the lead, which was doubled by Marcelo Estigarribia in the second period.

Mervan Celik pulled a goal back for the host with 15 minutes left before Lopez netted again and Gianluca Caprari scored a late consolation.

Bologna came from two goals down to claim its first points of the season with a 3-2 victory over shellshocked Roma at the Stadio Olimpico.

The Giallorossi looked to be cruising when Alessandro Florenzi and Erik Lamella struck in the first 15 minutes, but two goals in as many second-half minutes from Alberto Gilardino and Alessandro Diamanti brought Bologna back on level terms.

And there was one final twist in the dying seconds when Gilardino grabbed his second of the match after an embarrassing mix-up in the Roma defence.

Goals in each half from Steven Jovetic and Luca Toni handed Fiorentina all three points with a 2-0 win against Catania at the Stadio Artemi Franchi.

Montenegro forward Jovetic put the host ahead just before half-time and veteran striker Toni sealed victory moments after stepping off the bench.

Udinese was two goals in front after just five minutes but was held to a 2-2 draw by Siena, which hit back with a pair of second-half strikes after Andrea Lazzari's red card.

Dusan Basta put the visitor ahead after three minutes with a powerful effort, with Antonio Di Natale doubling the lead soon after from close range.

But the game changed when Lazzari received a second caution after 52 minutes as first Emanuele Calaio (70) and then Ze Eduardo, with a 77th-minute penalty, scored for Siena.

In the day's late kick-off, Inter Milan picked up its second away win of the season thanks to a 2-0 victory at Torino.

Diego Milito put the Nerazzurri ahead in the 14th minute and it resisted a spell of pressure from the home side before Antonio Cassano added the second seven minutes from full-time.

The win lifts Inter into the top five, leaving Torino beaten for the first time this season.
