Udinese have moved second, level on points with leaders Lazio, after a 2-0 win over Torino on Sunday.
Udinese claimed a straightforward success over the Turin outfit with a goal in each half from striker Fabio Quagliarella (44 & 77).
Following Lazio’s failure to win on Saturday, Udinese are now level with them and Inter – but they separate the two on goal-difference.
The late game saw bottom-of-the-table Cagliari hold AC Milan to a goalless draw on Sardinia – who are not three points off the top of the table.
Roma’s dismal start to the new league season shows few signs of abating after going down to a 1-0 defeat in Tuscany to Siena.
Liechtenstein ace Mario Frick fired Siena ahead just before the break and they held on to seal victory, although their cause was aided thanks to Roma having both central defenders – Christian Panucci and Philippe Mexes – dismissed.
Palermo find themselves in fourth after a very good 2-1 over Juventus.
Former Juve starlet Fabrizio Miccoli put the Sicilians ahead before Alessandro Del Piero levelled (39) but the home side were reduced to ten-men before the break when Mohamed Sissoko was dismissed for his second bookable offence.
Palermo grabbed the winner with just nine minutes left when Georgian starlet Levan Mchedlidze pounced.
Atalanta find themselves in fifth after a 4-2 home win over Sampdoria.
Antonio Cassano fired Samp ahead just seven minutes in but Atalanta had the lead at the interval thanks to Sergio Floccari (35) and Gyorgy Garics (39).
Cassano then levelled matters up with a penalty (54) before Floccari second restored on 77 minutes restored Atalanta’s lead.
Samp’s chances of taking something from the game were severely hampered when they saw two players dismissed as Pietro Accardi and Daniele Dessena.
Atalanta wrapped up the win with just minutes remaining with Cristian Doni firing home.
Fiorentina sealed a comfortable win in Verona with a 2-0 success over Chievo.

Ezequiel Lavezzi put Napoli ahead but Socratis Papastathopoulos levelled just before the break.
Raffaele Palladino (52) then put Genoa ahead before Marco Rossi saw red not long after.
Napoli could not take advantage of the extra man as Diego Milito (73) made it 3-1.
German Denis pulled one back for Napoli but they could not find the equaliser and the late sending off of Papastathopoulos could not spoil Genoa’s day.
Finally, Reggina are still winless after they were held to a 1-1 draw at home by Catania.
Michele Paolucci put Catania ahead on 69 minutes but his day was ruined moments later when he was dismissed.
Reggina took advantage of the extra man and levelled with ten minutes left through Andrea Costa.
