Was let down by his team-mates in the build-up to Cagliari's opener but, in truth, he really should have kept out what was a poorly-struck shot from Ibarbo.
Like Barzagli, struggled to contain Ibarbo at times. But stepped out of the defence to good effect, distributing the ball very constructively, as per usual.
Predictably fine defensive display from Chiellini, but he blotted his copybook with a stupid yellow card for diving in the dying seconds which rules him out of next weekend's game against Sampdoria.
A rare start for Marrone in midfield but he failed to make the most of it. Indeed, he was anonymous for the duration of the game.
Came off second best in an early challenge with Astori but did put over some decent crosses. However, given the amount of ball he saw, his final product just wasn't good enough.
Failed dismally to stop Ibarbo from opening the scoring, struggling to keep up with the Cagliari forward before then being simply barged out of the way. However, he was excellent thereafter and played a key role in Vucinic's equaliser.
Juve's utility man did a fine job on the left wing, tormenting Perico at every opportunity and creating chances for the likes of Vidal and Marchisio. Final ball does continue to let him down a tad, though.
Started very brightly, putting Giovinco in on goal and testing Agazzi with a fine strike from distance inside the opening 10 minutes. Continued to drive Juve forward thereafter and set up the equaliser with a clever downward header.
Busy enough up top but did not make the most of the half-chances that came his way, seeing the majority of his efforts blocked. Inevitably replaced by Quagliarella for the final quarter.
Made a mess of an early opening, taking far too long to get a shot away, but was so unlucky to see his measured free kick come back off the underside of the bar. Struggled thereafter, though, perhaps because of injury, and was replaced just after the break.
Lucky that the bar came to his rescue after being beaten all ends up by Giovinco's dipping free kick. But he made a string of solid stops and one spectacular save from a stinging Vidal drive.
Was given a rough ride by Giaccherini and it was something of a surprise that he was not hauled off at half-time, with Pulga waiting until just under 10 minutes into the second half to make a change.
A tremendously-timed sliding challenge on Isla six minutes in set the tone for a tremendously composed and committed display from the Italy international. Forced off through injury midway through the second half, though.
Typified Cagliari's dogged determination at the back with a terrific block on a goal-bound effort from Matri inside the opening quarter. Never let up from that point on.
Worked tirelessly but was booked for giving away the free kick with which Giovinco struck the bar, so he was wisely replaced early in the second period.
The captain led by example in the middle of the park, winning the ball back with great regularity and using it intelligently.
Caused problems every time he drifted out to the right-hand side, and provided his forwards with some decent service.
The Swede was extremely composed in possession and looked capable of making something happen every time Cagliari got the ball to him. However, he drifted badly out of the game the longer the second half wore on.
A lively presence in the middle of the park, the Belgian embarked on a few marauding runs and even tried his luck from distance on occasions. Another display that suggests that he could do a job for one of Italy's elite.
Tormented Barzagli early on. Indeed, he had already had a couple of nice early touches, cleverly lobbing the ball over the centre-half's head at one point, before then opening the scoring after a storming run from inside his own half.
Nowhere near as dynamic has his strike partner but still held the ball up well enough, taking the pressure off his defenders with a couple of fine runs down the flanks. Never looked like scoring, though.
Made an unexpectedly early entrance, coming on in place of the injured Barzagli with less than 15 minutes on the clock and performed well, even playing on after suffering a heavy knock.
Introduced less than 10 minutes into the second half and wasted little time in making his presence felt, heading home Vidal's knockdown to level matters. Very nearly won it with a curling effort at the death, too.
