Leaders Inter open up gap
Inter Milan extended their lead at the top of Serie A to five points despite being held by struggling Atalanta. Diego Milito gave the Nerazzurri the lead in the 14th minute, but Simone Tiribocchi equalised for the hosts in the 81st minute after Wesley Sneijder's 64th-minute red card had put Inter on the back foot.
AC Milan failed to take advantage as they lost 2-0 at home to Palermo. Milan, who came into the contest on the back of five successive wins domestically, were undone by second-half efforts from Fabrizio Miccoli and Mark Bresciano.
Aleksandar Kolarov stopped the rot for Lazio as his first-half goal sunk Genoa in an entertaining match at Rome's Stadio Olimpico. The Serbian left-back struck in the 39th minute to hand Lazio their first win in Serie A since 30 August.
Parma missed a penalty but still came from behind to beat ten-man Bologna and move clear in fourth place. Bologna took the lead moments before half-time through Gaby Mudingayi.
Christian Panucci headed Parma level in the 57th minute but Nicola Amoruso then missed a penalty after Miguel Britos had seen red for bringing down Blerim Dzemaili. However, Amoruso made up for it four minutes from time, tapping home after a neat move to seal the three points.
Elsewhere, Catania are now bottom after losing 1-0 at home to Livorno, Tomas Danilevicius grabbing an 87th-minute winner after Giuseppe Bellusci was sent off for Catania. Siena climbed off the bottom with a 2-1 win over Udinese, Massimo Maccarone (66) and Abdelkader Ghezzal (90) grabbing the crucial goals.
Chievo beat Fiorentina 2-1 to move above them in the table, Giampiero Pinzi (11) and Gennaro Sardo (23) scoring as the home side recovered from Riccardo Montolivo's fifth-minute opener. The game between Sampdoria and Roma ended goalless.
