Juventus eased to a comfortable 3-1 win over bitter rival Inter Milan in the Italian league on Sunday to extend their lead at the top of the table to nine points.

Stephan Lichtsteiner, Giorgio Chiellini and Arturo Vidal scored for Juventus before Rolando grabbed a consolation for Inter in the match known as the derby d'Italia - Italy's derby.

Antonio Conte's team extended its lead over second-place Roma, which saw its match against Parma abandoned after eight minutes due to a waterlogged pitch.

"We won and we're happy," Conte said. "We prepared the match well in all the details, I think we played well. I'm disappointed we conceded, that made us a bit anxious. We need to keep the tension high until the end."

Juventus also moved 15 points ahead of Napoli, which fell to a surprise 3-0 loss at Atalanta as German Denis struck twice against his former club.

"We had three or four good counterattacks and then we made a mistake," Napoli coach Rafa Benitez said. "Then we had another chance but then we again made a mistake, and then there was another mistake. In summary, we gifted them three goals.

"Teams put a lot of men behind the ball against us so it's difficult to find space, but when we have chances we have to score. It wasn't my team selection which made the difference today, but mistakes."

At the other end of the table, Catania drew 3-3 at home to Livorno in a tense relegation battle between the two bottom clubs in Serie A. Sassuolo also remained in the relegation zone after new coach Alberto Malesani's debut ended in a 2-1 defeat at home to former club Hellas Verona, which snapped a run of three successive defeats.

Lazio continued their resurgence under Edy Reja as they comfortably beat Chievo Verona 2-0. Juventus almost took the lead with less than three minutes on the clock but Inter goalkeeper Samir Handanovic pulled off a fantastic double save to deny Carlos Tevez from point-blank range.

The home side did go in front in the 16th minute when Lichtsteiner was left unmarked to send a diving header into the bottom left corner following a great ball from Andrea Pirlo.

Inter should have reduced the deficit shortly before half-time with their first real chance of the night but Rodrigo Palacio fired narrowly over the bar.

Juventus doubled their lead two minutes after the break when Chiellini - who was wearing the captain's armband in place of the suspended Gianluigi Buffon - capitalized on Paul Pogba's persistence to bundle the ball into the back of the net.

Vidal sealed the match eight minutes later, slotting home the rebound after Handanovic had saved Pogba's effort. Roland fired into the far bottom corner, through a crowd of bodies to reduce the deficit in the 71st.

Mirko Vucinic came off the bench for Juventus four minutes from time and he almost scored against the club he nearly joined, but saw his effort deflected off the left upright.

Napoli instigated their own downfall in Bergamo as a series of defensive howlers led to a crushing defeat. Atalanta broke the deadlock less than two minutes after half-time. Blerim Dzemaili gave the ball away in midfield and Denis' powerful drive from outside the area bounced under the diving Napoli goalkeeper Pepe Reina.

Denis - who spent four years at Napoli - doubled his tally in the 65th minute when he latched on to a poor attempted clearance from Gokhan Inler and fired across into the bottom left corner.

Maxi Moralez sealed the result five minutes later following another error from Federico Fernandez. Roma's match against Parma was abandoned after only eight minutes' play, with the score at 0-0.

Bottom club Catania remained two points behind Livorno after an entertaining draw, which helps neither club in the relegation battle. Catania fought back from a goal down three times as Innocent Emeghara scored twice for Livorno, which also had a penalty converted by Paulinho.

Gonzalo Bergessio and Pablo Barrientos scored for Catania, and the home side leveled for the third time in the final minute when substitute Sergio Almiron was left unmarked at the far post to control and fire in a cross.

Oh,no.The Milan isn't the old eighter.
