Juventus lost their clean sheet after 744 minutes of Serie A football, but still beat Atalanta for a ninth straight victory.
The Bianconeri had won their last eight Serie A games without conceding and visited an Atalanta side who hadn’t won in four. However, the Stadio Azzurri d’Italia had also not been conquered in five games, taking points off the likes of Inter and Roma here. Andrea Pirlo and Mirko Vucinic were still sidelined, while the hosts missed Mario Yepes, Cristian Raimondi, Stefano Lucchini and Gianpaolo Bellini.
Juve are unbeaten in this fixture since a 2-1 result in February 2001, earning seven victories and a draw, and have won their last six meetings with Atalanta, home and away.
Atalanta wore a new red Christmas-themed shirt and the snow and rain in Bergamo added to the atmosphere.
It took just six minutes for Juve to break the deadlock, as Carlos Tevez skipped away from defenders to shoot with his right foot from the edge of the box and Andrea Consigli got a hand to it, but not enough to keep the ball out of the bottom corner.
Atalanta equalised with Maxi Moralez, the first goal the Bianconeri had conceded in 744 minutes of Serie A football. The little Argentine gathered the pull-back and his shot went in off the inside of the upright.
Consigli intercepted a dangerous Kwadwo Asamoah cross that Fernando Llorente was about to tap in, while Paul Pogba hit the crossbar only after a push on Guglielmo Stendardo.
A Carlos Carmona screamer was just wide, then Tevez got between defenders and Consigli had to flap the ball away in the six-yard box.
Tevez sprung the offside trap to go clear on goal, but Consigli did just about enough to send him wide and the chance went begging.
Juventus restored their advantage straight after the restart. Llorente knocked down an Asamoah cross for Pogba, who turned in from six yards.
Claudio Marchisio blasted over the bar, but Llorente secured the victory when he gathered from Giorgio Chiellini and turned Migliaccio inside out to score.
Arturo Vidal added his name to the scoresheet when meeting a Stephan Lichtsteiner ball across the six-yard box.
