Was deceived by the ingenuity of Pirlo's free kick. In saying that, he got a hand on the ball and will be disappointed at having failed to keep it out. More than made amends by denying Marchisio with a stunning save just before half-time, and also did well to get something on Giovinco's attempted dink just after the restart. Was unlucky to be beaten for a second time at the death.
Signalled his attacking intent two minutes in by getting in behind De Ceglie down the left-hand side and then picking out Sestu, only to see the midfielder scuff his shot. Calaio made no mistake, though, after Angelo had used his pace and power to storm past De Ceglie for the umpteenth time just before the interval, before sending over a terrific cross to the back stick. His influence waned in the second-half, though, and he was hauled off on 68 minutes.
Struggled to contain Giovinco right from the off and was booked just 14 minutes in for bringing the diminutive forward down on the edge of the area, an indiscretion which was then further punished by Pirlo's subsequent conversion of the resultant free kick.
C. Del Grosso
His defending was neat and tidy throughout, and he used the ball smartly and effectively, always looking to work Rosina into decent attacking positions during the second-half. Also produced a sublime cross that the midfielder really should have buried.
Cannot fault his effort but was repeatedly made to look a little flat-footed and cumbersome by Giovinco and Vucinic.
Was a little heavy handed in his defending at times, but was an influential figure at the back for Siena. Indeed, it was he who was on hand to clear after Giovinco had lifted the ball over Pegolo just after the break.
A spirited showing from the captain, best summed up by the way in which he won one duel - thus relieving the pressure on his side - by dispossessing Asamoah despite being on the floor. However, he was left chasing shadows during the second-half.
An energetic and aggressive presence in the middle of the park, the Uruguayan really put himself about and put in a number of crunching tackles, most notably on Pirlo, who was less than impressed by being on the receiving end of a couple of late challenges. Also went close to scoring with a header.
Worked tirelessly and linked reasonably well with Calaio and had a number of nice touches, one of which really should have resulted in his centre forward drawing Siena level on 23-minutes. Stupidly talked himself into a booking after believing himself to have been fouled by Vidal and was ultimately brought off just after the break.
Sparked the move which led to the early opening for Rosina but wasted a gilt-edged opportunity to make it 1-1 when he shot wide after being given a clear sight of goal by a sublime lay-off from Ze Eduardo. However, he made amends right on half-time by burying Angelo's cross from the right. Did not get another good chance thereafter, though.
A real livewire performance from Rosina, who was always keen to take the game to Juve. Squandered a great chance to open the scoring inside two minutes but he was involved in all of Siena's best attacking moves and De Ceglie's withdrawal at half-time was testament to that. However, his finishing let him down again in the second-half when he failed to connect with Del Grosso's cross.
Saved easily from Rosina early doors and did not actually have too many saves to make before Calaio left him with no chance with a close-range header. Did wonderfully well to tip Chiellini's attempted clearing header over the bar.
P. De Ceglie
Got forward on occasions and put over a couple of dangerous crosses from the left-hand side but, for the most part, he spent his time trying to contain Angelo and Rosina - with little success. Indeed, it was absolutely no surprise that Siena's equaliser came down De Ceglie's side as he had allowed Angelo to get in behind him as early as the second minute. Wisely replaced at the break.
Looked unusually shaky early on and saw yellow for barging Rosina off the ball. Then ran the risk of being dismissed for a second bookable offence after crashing into Felipe. Very nearly put through his own goal during the second-half, but then played a key role in Marchisio's winner by nodding the ball back across the box.
Threatened sporadically during the first-half, with his strong running and accurate deliveries into the box. Indeed, Giovinco should have converted one such ball into the box after being picked out by the Swiss just six yards out. However, he was not as menacing after the break and made way for Giaccherini midway through the second period.
Caused some discomfort by Siena's neat link-up play every now and then, but, overall this was another composed performance from the centre-half.
By no means his best performance, the Chilean was sloppy in possession in the first-half and also mistimed a couple of tackles. Improved after the break, though, and called Pegolo into action at one point.
Influential as ever, the playmaker settled Juventus by netting the opener 14 minutes in, finding the bottom corner of the Siena goal with a low strike that took advantage of the players in the wall jumping to make themselves big. Created a fine opening for Giovinco with a terrific ball before going so close to doubling Juve's lead with a stunning set-piece on 39 minutes only to see his curling 25-yard effort crash off the bar.
Deployed at the back, Marrone's distribution was unsurprisingly accurate and Pirlo struck the bar with a free-kick that the midfield had earned with a strong surge out from the back. However, he looked uncomfortable at times, most notably when he flattened Rosina with a mistimed challenge.
The most dynamic player on the pitch. Had his first sight of goal 11 minutes in but his 25-yard drive was always going over. However, he looked set to make it 2-0 to Juve just before the break but after killing a pass from Pirlo and then nimbly stepping inside Neto, his curling effort from the edge of the area was wonderfully kept out by Pegolo. Eventually - and deservedly - got on the scoresheet with five minutes to go by firing home after a trademark late arrival in the area.
Did not manage to get among the goals but he did play an integral role in both, winning the free kick that Pirlo fired home before producing the cross that led to Marchisio's late winner.
Linked well with Giovinco in the first-half, most memorably when he dropped deep to great effect, spinning his way past two players before releasing his strike partner. Very nearly found the bottom corner with a measured effort in the second period but was ultimately unable to get on the scoresheet.
Replaced De Ceglie for the start of the second-half and was a far more reliable and assured presence on the left-hand side.
Came on for Lichtsteiner but while he was full of running, the Bianconeri's utility man did not make a great difference down the right-hand side.
