ROME, Dec. 22 (Xinhua) -- Roma ended their 2012 campaign on a resounding note as they thrashed AC Milan 4-2 at home on Saturday, while their cross-city rivals Lazio moved up to second in Serie A with a 1-0 win at Sampdoria.
Nicolas Burdisso, Pablo Osvaldo scored once and Erik Lamela twice to put the home side 4-0 up in just over an hour, and Zdenek Zeman's side moved up to the sixth place with the win.
Roma struggled a little bit late in the second half after Marquinhos was sent off with 13 minutes left for handball.
Milan waged a late rally and scored two goals in the last five minutes.
"I think we need to improve our defending, but I did not see any big mistakes tonight," said Milan coach Massimiliano Allegri.
"Maybe we weren't aggressive enough on their counter-attacks, probably because we feared Roma's forwards," he said.
Lazio chalked up a 1-0 win at Sampdoria and leapfrogged Inter to the second place of the table, eight points behind champions and league leaders Juventus.
Andrea Stramaccioni's Inter moved down to fourth after Esteban Cambiasso's equaliser five minutes from time cancelled out Ciro Immobile's superb individual goal for second-bottom Genoa.
Inter are now nine points off the top going into the Italian mid-season break.
Fiorentina climbed back to the third spot with a 3-0 win over troubled Palermo as Stevan Jovetic netted twice, including a penalty, and Gonzalo Rodriguez scored with another spot-kick.
Napoli scored twice in the last five minutes to claim a dramatic 2-0 win at bottom club Siena.
Atalanta's German Denis struck a 40th-minute penalty, his seventh goal of the season, to give the hosts a 1-1 draw with Udinese, who had taken the lead seven minutes earlier through Luis Muriel's first goal of the campaign.
Torino saw off Chievo 2-0 in Turin while Parma won 2-1 at Bologna thanks to second-half goals by Jaime Valdes and Nicola Sansone after Frederik Sorensen had given the hosts the lead nine minutes after the break.
