Inter Milan moved to the top of the Serie A standings thanks to a 4-0 hammering of Frosinone.
Roberto Mancini's side headed into the fixture a point adrift of Napoli and Fiorentina, but two goals in each half saw them leapfrog their rivals.
Jonathan Biabiany opened the scoring in the 29th minute as Inter's dominance finally reflected on the scoreboard, with the forward on hand to strike home a rebound.
Mauro Icardi's effort in the 53rd minute put the Nerazzurri in complete control, with late goals from Jeison Murillo and Marcelo Brozovic adding further gloss to the victory, the first in which Inter have won by more than a single goal.
Earlier, Napoli had briefly gone to the top of the standings after a 2-0 win away to Verona. The hosts struggled to deal with the attacking prowess of the visitors in the opening half, and Napoli missed three clear goal scoring opportunities.
Gonzalo Higuain was judged to be offside when he found the back of the net in the 28th minute, much to the Argentine's disgust. Naploli would finally get on the board in the 67th minute when Lorenzo Insigne netted from close range. Insigne was involved in the second goal too, putting Higuain into space for an easy finish which sealed the win.
Genoa stunned Sassuolo with a last minute goal to win 2-1 at home. The cagey match was thrown wide open when Sassuolo's Domenico Beradi and Genoa's Diego Perotti were sent off within a minute of each other for illegal challenges.
Tomas Rincon struck first for the hosts with a fantastic effort from 18 metres out. Francesco Acerbi then hushed the Genoa crowd with a lucky goal that deflected off a defender in the 94th minute. But Genoa showed great composure to strike back just 60 seconds later, with Leonardo Pavoletti firing a bullet header into the back of the bet to steal a victory.
Fiorentina have Nikola Kalinic to thank for his brace that lead to a 2-2 draw at home against Empoli. Marko Livaja latched on the end of a Riccardo Saponara pass to open the scoring for the visitors. They doubled their lead when a blocked shot landed at the feet of Marcel Buchel who fired the ball home from close range.
Kalinic would strike twice in quick succession early in the second half to save the game for Fiorentina and give them a valauble point which saw them join Napoli at the top of the table before being later surpassed by Inter.
Torino edged Atalanta by one goal when they travelled to Bergamo. Cesare Bovo would scored the only goal of the match in the second half. The right back controlled Daniele Baselli's corner and sent the ball flying into the back of the net in a superb finish.
Carpi were unable to recover from a quick-fire two goals from Chievo, going down 1-2 at home. Roberto Inglese rose above the Carpi defenders to fire home a close range header in the eighth minute. Just six minutes later, Riccardo Meggiorini drilled the ball into the bottom right hand corner.
In the second half, Alessandro Gamberini would score an own goal after some confusion in Chievo's own box.
Lazio held Palermo to a 1-1 draw at home. The visitors went 1-0 up after a deflected shot arrived at the feet of Edoardo Goldaniga who sent the ball flying into the bottom left corner.
The hosts would have to wait until the 70th minute to equalise, when Antonio Candreva slammed home a penalty after a foul from Oscar Hiljemark. Lazio were unlucky not to score a late winner, with Palermo stopper Federico Marchetti pulling off a great save to deny Luca Rigoni in the 76th minute.
Badu's goal in the 35th minute was the only thing that separated Udinese fromSampdoria. The visitors would lament their missed opportunities, as they failed to convert three great scoring chances.
