Napoli moved to the top of Serie A with a 3-0 win over ten-man Inter Milan at the San Siro.
Napoli won a penalty four minutes before the break when Joel Obi was sent off for a second bookable offence for bringing down Christian Maggio.
Marek Hamsik saw his resulting spot-kick saved by Inter keeper Julio Cesar, but Hugo Campagnaro was on hand to fire home the rebound.
Maggio added a second for Napoli on 57 minutes when he capitalised on some hesitant defending from Yuto Nagatomo to lift the ball over the onrushing Cesar.
Napoli rounded off their convincing victory when Ezequiel Lavezzi slipped Hamsik in on goal and he slotted his shot past Cesar to compound Inter's misery.
Roma picked up second successive win with a 3-1 victory over previously unbeaten Atalanta at the Stadio Olimpico.
Goals from Bojan Krkic, Pablo Osvaldo and Simplicio were enough to give the capital side the three points with German Denis netting a consolation for Atalanta.
Bojan broke the deadlock on 20 minutes when he latched onto Daniele De Rossi's pass over the top to fire past Atalanta keeper Andrea Consigli.
Osvaldo added a second just past the half-hour mark with his third goal in as many games for Roma.
Atalanta gave themselves hope when they pulled a goal back three minutes into the second half when Denis headed home.
However, Roma made the game safe nine minutes from time when Simplicio played a one-two with Miralem Pjanic before chipping the ball over Consigli.
