AS Roma, boasting one of the best attacking records in Serie A and also suffering one of the worst defences, continued their wildly unpredictable season by storming back from two goals down to win 4-2 at Genoa on Sunday.
Antonio Cassano scored his fifth goal of the season to help Inter Milan beat Catania 2-0 in a match featuring 13 Argentines among the 22 starters.
Udinese's Brazilian Maicosuel, playing only his second game since his infamous penalty shootout miss against Braga cost his team a lucrative Champions League place, scored as they beat Pescara 1-0 despite playing for an hour with 10 men.
Two goals from Amauri gave Parma a 2-1 win over Sampdoria, who had Argentina goalkeeper Sergio Romero sent off for giving away the penalty which led to the opener nine minutes before halftime.
Atalanta came from behind to beat fellow strugglers Siena 2-1, Chievo drew 1-1 at home to Fiorentina and Cagliari beat Bologna 1-0 in the other games.
Inter's sixth win in eight Serie A games this season kept them fourth with 18 points, four behind leaders Juventus who beat second-placed Napoli 2-0 on Saturday. Roma climbed to fifth with 14 points.
Sunday's game began disastrously for Roma as Juraj Kucka and Bosko Jankovic swept Genoa to a 2-0 lead in only 15 minutes.
Thirty-six-year-old Francesco Totti, in his 21st season at his only professional club, pulled one back from inside the penalty area in the 28th minute and Pablo Osvaldo hooked in the equaliser one minute before the break.
That set up a second half of Roma dominance which saw Osvaldo head them in front in the 55th minute and Argentine midfielder Erik Lamela curl his shot into the bottom corner with seven minutes to play.
Udinese moved on to nine points with their win against promoted Pescara, Maicosuel scoring from close range in the 53rd minute after the visitors failed to cut out Pablo Armero's cross.
