Juventus 3-0 Roma
Juventus moved eight points clear at the top of Serie A after beating second-placed Roma, who were reduced to nine men.
Arturo Vidal stabbed in the opener with Juve's first attack before Leonardo Bonucci volleyed home a second.
Roma had two players sent off within a minute as Daniele De Rossi fouled Giorgio Chiellini before Leandro Castan handled on the goalline.
Mirko Vucinic then scored from the penalty spot to complete the win.
Roma finished 2013 somewhat disappointingly after a blistering start to the season, drawing five of their last seven games, but they arrived at the Juventus Stadium without a defeat in their first 17 matches.
Initially, they looked more like the side that won their first 10 games as they kept Juve back inside their own half, confidently passing the ball around as they patiently searched for an opener.
In contrast, Juventus offered little in the opening 15 minutes, but their first attack produced the game's first goal as Carlos Tevez spun superbly before threading the ball to Vidal, who slotted the ball into the net from close range.
Roma looked to respond immediately as Miralem Pjanic forced a save out of Gianluigi Buffon with a shot from 20 yards, before the Juventus goalkeeper spilled another effort from the midfielder.
But Juventus finished the half stronger as Paul Pogba had a shot charged down while Tevez lashed an effort across the face of goal before the break.
Half-time offered Roma a chance to regroup but found themselves further behind within three minutes of the second half.
Pjanic fouled Kwadwo Asamoah on the left flank, presenting Andrea Pirlo with the opportunity to deliver a typically dangerous free kick into the area. The Italy veteran did not disappoint as he curled the ball towards the far post where Bonucci was left unmarked to poke home.
There was still plenty of time after that goal for Roma to mount a fightback but they failed to threaten before an ineffectual Francesco Totti was withdrawn with 20 minutes remaining.
It got worse for Roma in the closing stages as De Rossi needlessly fouled Chiellini and was shown a red card. From the resulting free kick, Pirlo sent the ball into the area and Bonucci headed towards goal, where defender Castan punched the ball clear. He promptly followed De Rossi down the tunnel.
Substitute Vucinic smashed the penalty beyond goalkeeper Morgan De Sanctis to complete a miserable defeat for Roma.
