The Italy defender popped up with the equalising goal in the second half to ensure his side narrowly increased their lead at the top of Serie A
Juventus missed the chance to go 10 points clear at the top of Serie A after being held to a 1-1 draw by Udinese.
Duvan Zapata scored the opening goal after 37 minutes and it was no more than the home side deserved as Luigi Delneri's men looked the better team for long periods at the Stadio Communale Friuli.
Massimiliano Allegri's champions looked disjointed and lacked their usual fluency in attack, while Udinese's pressing game and well-organised defence further restricted their opportunities to score.
