Little he could do about the game's opening goal, having been so badly let down by those in front of him, and kept the tie alive with a fine stop from Floccari right at the death.
Brilliantly dispossessed Ederson just as the Brazilian was about to let rip 10 minutes in and also made a terrific block on a shot from Hernanes. Also caused problems when he went forward for set-pieces. However, was repeatedly caught out of position in the second half.
Looked suspect when left one-on-one with the likes of Candreva, who left the Japanese trailing in his wake at one point during the first half, but he was arguably Stuttgart's most reliable defender.
The centre-half underlined his bravery by throwing his body in the way of shots from Candreva and Kozak. Also tried to help out his side's misfiring strikers, even getting forward at one point to get on the end of a volley from Macheda, only to volley over. However, he was almost totally to blame for Onazi's goal by effectively stepping out of the Nigerian's way.
Was always looking to get forward in support of Gentner but perhaps should have focused more on his defensive responsibilities, given he contributed to his side falling behind by failing to clear before Ederson fired home.
Just like team-mate Boka, the Dane must also accept a huge portion of the blame for the opener for failing to clear the danger. Never really recovered from that mishap and was hauled off early in the second half.
Stuttgart's best attacking outlet in the first half, Gentner produced two cracking crosses, both of which should have been converted by Okazaki, as well as creating a shooting opportunity for Traore after a fine surge down the left wing. However, he was anonymous after the restart.
Fired high and wide after being set up by Gentner in the opening quarter but did what was asked of him reasonably well, getting up and down the left-hand side of the pitch to great effect.
Made an eye-catching surge from deep midway through the first half, so it was unfortunate his evening was brought to a premature end by injury.
Drew a fine save from Marchetti with a powerful header early on, but did not even manage to hit the target after being picked out unmarked inside the six-yard box just before the break. Also volleyed wide after doing well to get past Cana on the edge of the area. Was a constant menace, but his finishing let him down badly.
Never looked remotely like scoring against the team he supported as a boy but he worked tirelessly up top on his own and created a few openings with some neat lay-offs.
Not exactly overworked but played a crucial role in a positive result for the visitors by pulling off a stunning reaction save to keep out Okazaki's powerful header while the game was still scoreless.
Caused a spot of bother whenever Gentner popped up on Stuttgart's right-hand side but, for the most part, the skipper was solid as a rock.
Defended stoutly but will probably be a tad disappointed that he didn't get on the scoresheet after connecting powerfully with a Candreva corner during the first half.
The Albanian turned in a relatively composed performance at the back for the Biancocelesti, though he was caught out by Okazaki on a couple of occasions.
Could have easily gone into his shell after an embarrassing early strike on goal which went out for a throw, but grew in confidence the longer the game went on and he capped a dynamic display with a stunning solo goal.
Asked so many questions of the Stuttgart defence with his movement and guile before being withdrawn 20 minutes from time with the game won.
Caused chaos every single time he got time on the ball, creating a host of opportunities, the best of which Ederson wastefully headed over the bar.
Twice went close to scoring and was a decent outlet down the right flank, but drifted in and out of the game.
Badly misjudged a straightforward crossfield ball early on, thus allowing Gentner to get in behind him, but went from strength to strength thereafter.
Looked determined to make an impact right from the off, with a couple of jinking runs and blocked shots. Came as no surprise when he popped up to open the scoring with a smart finish after a neat turn. Should have had a second goal just before the break, too.
Worked hard, particularly in terms of bringing others into the game, but never got a clear sight of goal himself.
