Angelo Da Costa
Unlucky to be on the losing side as he made some fine saves, especially in the first half.
Gave the ball away too many times, inviting pressure right back onto his team.
Paid very close attention to Mirko Vucinic whenever the Montenegrin tried to pull wide off the ball. Solid display.
L. De Silvestri
Got forward more often as the game progressed, causing problems on the right, even inadvertently testing Buffon with a wayward cross.
Could not contain Lichtsteiner out on the flanks and was often left scrambling in vain to prevent the overlap.
Toiled diligently all game long in midfield, and worked very hard to close down space.
Bypassed far too often in the middle of the park in a forgettable game for him.
Often got himself in the way of the ball to prevent dangerous openings for the opposition, and was his usual brave self.
Lost out a few times in the physical battle with Poba and Asamoah, but flashed a powerful effort just wide.
A nuisance at times in the box, but he could never channel that into an outright goal threat.
The main attacking outlet for the home side, as his guile on the ball fashioned most of the little openings they had.
Made a strong save from De Silvestri in the second half, but was not called into action much otherwise.
Found it hard to deal with the unpredictable nature of the ball and was responsible for one or two Sampdoria near misses.
The centre back did not put a foot wrong throughout, and was particularly useful during the closing stages with his safety first approach.
Overlapped on the right with plenty of intent, and provided a strong outlet for Juve down that side. Overreacted to a challenge that led to Castellini's dismissal.
Solid at the back, holding his position well and proving a good deterrent for the visiting attackers.
Provided the midfield with a lot of physicality, and was heavily involved in the goal, making a good run off the ball and squaring for Carlos Tevez to finish.
Motored from end to end in a tireless display, and refused to let the rain deter him from doing his job. In fact, he seemed to relish the gritty nature of proceedings, and disrupted a few attacks.
His passing was hit or miss thanks to the state of the pitch, but he kept his head to thread in Paul Pogba, who then set up the opener.
Could not get into his usual stride, and was uncharacteristically inaccurate from set-pieces. Tested Da Costa early on.
Combined well with strike partner Mirko Vucinic on one or two occasions, and took full advantage of a flowing Juve move to tap home the only goal of the game.
One or two moments of link-up play aside, he was rather stymied up front as the conditions and stout defensive attention took their toll.
