Champions Juventus remain top after restoring their three-point lead over Napoli, 2-0 winners at home Saturday against Catania, thanks to a 2-1 win away to Chievo.
Lazio's third place, however, is now under threat after a 3-2 reverse at Genoa which left Vladimir Petkovic's side only three points ahead of Milan and Inter Milan, with Fiorentina, in sixth, a further point off the pace.
As Inter dropped more points in a shock 3-1 defeat away to Siena, city rivals Milan stole the limelight thanks to a Balotelli double on what was the 22-year-old's debut following his transfer from Manchester City in midweek.
Balotelli, a former Inter Milan player, told the media on his presentation Friday evening he had come to Milan "to help the club win trophies".
After seeing a drive whizz just past the post on 35 seconds it took him just 25 minutes to show fans of his intentions when he latched on to a through ball to smash the ball past Daniele Padelli in the Udinese goal.
Udinese pulled level in the 55th minute when Giampero Pinzi beat Marco Amelia in the Milan goal after being set up by Colombian Luis Muriel.
However, Balotelli made sure of all three points in the fourth minute of injury time when he beat Padelli from the spot after the referee deemed Thomas Heurtaux's challenge on Stephan El Shaarawy to be a foul.
