A review of the weekend's action in Italy's Serie A.
Juventus beat city rivals Torino 1-0 thanks to a thunderous strike from Carlos Tevez and pulled nine points clear at the top of the Serie A table.
Tevez's clever shot on the turn after 30 minutes of the latest Turin derby proved enough to restore the Italian champions' advantage over Roma, after the capital club edged out Bologna on Saturday night.
Lazio emerged victorious after four goals in 11 frantic second-half minutes lit up the Stadio Olimpico and condemned Sassuolo to a sixth straight Serie A defeat.
Europa League-chasing Lazio appeared happy enough to cling onto a slender lead after Stefan Radu added some excitement to a dull first half with a rare defender's goal.
But, as soon as Sassuolo equalised through Sergio Floccari in the 72nd minute, Lazio went all out for the win, shrugging off Antonio Floro Flores' response to a Miroslav Klose strike to win the game 3-2 thanks to Radu's second.
Lazio remain in 10th place but could climb as high as seventh with victory at Fiorentina next week.
Sassuolo, meanwhile, are rooted to the bottom of the table, three places and four points behind 17th-placed Bologna.
AC Milan bounced back from their Champions League setback with a 2-0 victory at Sampdoria.
The Rossoneri, who were beaten 1-0 at home by Atletico Madrid in the first leg of their last-16 clash on Tuesday, took a 12th-minute lead against Samp through Adel Taarabt.
Adil Rami made it 2-0 before the hour mark.
The hosts shot themselves in the foot when former AC Milan striker Maxi Lopez was sent off 18 minutes from time for a second yellow card, both bookings for dissent.
Udinese captain Antonio Di Natale's second-half equaliser denied Atalanta their first win on the road since October 5 as they shared the points in a 1-1 draw.
The Bergamaschi looked to be heading for a long overdue win when Davide Brivio gave them a 24th-minute lead at the Friuli stadium.
However, Di Natale earned and converted a penalty 19 minutes from time to earn his side a share of the spoils.
Inter Milan and Cagliari shared the points in an entertaining 1-1 draw at San Siro.
Mauricio Pinilla's penalty gave Cagliari a half-time lead but Inter equalised early in the second period, defender Rolando credited with the goal.
Chievo halted a 10-match winless run with a 2-0 triumph over Catania.
Cyril Thereau converted from the penalty spot in the 37th minute to put the hosts on their way.
Luca Rigoni secured all three points by scoring his team's second in the 68th minute.
A second-half fightback from relegation-battling Livorno fell short as Hellas Verona hung on for a 3-2 win in Tuscany.
Three goals in the final 15 minutes of the first half from Bosko Jakovic, Romulo and Luca Toni put the visitors firmly in control, 3-0 up at half-time, but Livorno made a fight of it as Paulo Betanin and Leandro Greco scored two in the space of two minutes with less than 20 minutes to go.
On Saturday, Roma clung on tight to a slender lead at relegation-threatened Bologna to edge a 1-0 victory.
Radja Nainggolan scored his first goal for the Giallorossi since moving from Cagliari in January, but Roma failed to put struggling Bologna to the sword and ended up retreating to resist a late backlash.
