Juventus pulled 10 points clear of Serie A title rivals Roma with a convincing 3-1 victory over AC Milan.
Despite their inconsistent form, the Rossoneri certainly have the potential to match Juve and the league leaders made sure to put them in their place early on through a goal from Carlos Tevez.
Recent signing Luca Antonelli pegged the reigning champions back ever so briefly but Leonardo Bonucci's strike gave Juve the confidence to push on and consolidate the win through Alvaro Morata.
The fixture was afforded extra spice by the element of revenge on offer as home boss Massimiliano Allegri looked to get the better of the man he suspected was behind his ousting from Milan last year.
And Juve would draw first blood against Filippo Inzaghi's Rossoneri as Tevez notched on 14 minutes.
Alex's poor header in midfield allowed Morata to send the Argentinian through on goal and Diego Lopez could not resist his searing left-footed finish.
The game remained wide open from that point forward and Tevez drew ripples of applause when he whipped a second screamer just past Lopez's far post.
But it was Milan who scored next, with Antonelli opening his account on his debut.
In the 28th minute Alessio Cerci took a corner that found the former Genoa defender and he headed home.
Juve responded immediately but would have to knock twice before re-establishing their lead.
Lopez was at full stretch to tip Claudio Marchisio's low effort around his far post after Sulley Muntari had lost concentration in defence.
From the resulting corner, though, Bonucci converted an easy tap-in.
Milan suffered another setback as in-form French forward Jeremy Menez limped off to be replaced by Giampaolo Pazzini, but they would avoid conceding in embarrassing fashion as Lopez managed to cover Michael Essien's careless backpass in the 41st minute.
Gianluigi Buffon turned on the heroics to deny Pazzini when play resumed -- the former Inter Milan striker had snaffled Antonelli's clever through-ball before being denied.
Juve shrugged off the reaction and extended their lead in the 65th minute.
Marchisio wriggled into enough space to drive a low shot against the far post, and the rebound fell kindly for Morata to steer it into an unguarded net.
The Bianconeri had a fourth goal ruled out for offside. A great attacking raid saw Paul Pogba try his luck with a bicycle kick, yet Morata was in an illegal position as he stuck away the loose ball.
Ninth-placed Milan were deflated but did well to survive another Juve raid which saw Gabriel Paletta anticipate Tevez's movement and Lopez close down Marchisio before he could exploit the chaos.
