Inter Milan's hopes of playing in Europe next season suffered a further setback as they were held to a 0-0 draw by Atalanta at the end of a week in which they were knocked out of the UEFA Champions League. Diego Milito missed a penalty midway through the first half, but Inter never looked settled in a scrappy Serie A encounter.
Napoli came from two goals down to claim a point in a 2-2 draw with Udinese at the Stadio Friuli. Giampiero Pinzi put the home side ahead in the 28th minute with Antonio Di Natale doubling their advantage early in the second half.
Diego Fabbrini was sent off after an hour and Udinese failed to defend their lead with ten men as two goals from Edinson Cavani, who also missed a penalty, earned Napoli a point. Udinese coach Francesco Guidolin was also sent off in a tense finale with the draw helping both sides move to just a point behind Lazio in the race for third place.
Catania stun Biancocelesti
Lazio slumped to a 1-0 defeat at Catania, with a goal ten minutes from time from Nicola Legrottaglie proving decisive. Bologna twice came from behind to snatch a draw at home to Chievo.
Marco Andreolli put the visitors in front midway through the first half, but Marco Di Vaio levelled in the 59th minute. Cyril Thereau restored Chievo's lead, but again they could not hold out and Alessandro Diamanti made it 2-2 nine minutes from time.
Lecce remain in relegation trouble after a 1-1 draw with Palermo. David di Michele put them ahead with a fifth-minute penalty but Ezequiel Munoz levelled for the Sicilians ten minutes later and both sides ended the game with ten men after the first-half sendings off of Massimo Oddo and Nicolas Bertolo.
Goals inside the final 20 minutes from Marco Rigoni and Filippo Porcari lifted Novara to a crucial victory at Siena - the second-bottom club are now within eight points off safety after a second successive win - while Mauricio Pinilla's hat-trick earned Cagliari a 3-0 win over struggling Cesena at the Stadio Sant'Elia.
