In quite superb form. Three times denied Gotze in the first half, twice in very quick succession, demonstrating superb anticipation. Constantly in demand in the second half and constantly responded. Perhaps could have got a stronger hand to Reus' opener but, in general, the last man whom City could blame for the result.
Made some key interceptions at the back and looks the most reliable of City’s defenders right now.
Came off the worse in the contest between him and Blaszczykowski and it was only a matter of time after Kolarov came on that he would be sacrificed should City need a goal, Balotelli replacing him for the final 10 minutes.
Still lagging a little behind his totemic form of last season. The Belgian seems more sluggish than usual of late and this brought him a booking as he could only barge the pacy Reus over to stop him getting past. Will miss the Ajax game as a result.
Just as at the Santiago Bernabeu, the Serbian youngster looked more composed at the back than the somewhat-faltering Kompany but was still pulled around here and there by the visitors' movement. Let down by Rodwell for Reus' opener.
With Dortmund often attacking more than the hosts, the Frenchman notably squandered one good opportunity to break because of his relative lack of pace, having to cut inside and hold play up instead. Never made an impression on the game and was replaced by the more direct Kolarov.
Was starting to grow into the game more by the time he went off injured after just over half an hour. Had been somewhat overrun by Dortmund’s constantly pressing forward line early on.
It is always a treat to watch the Spaniard make a pass and he picked some out on Wednesday of brilliant audacity and precision. If only he had passed into the net rather than awkwardly hoicked over from very close range in a late-first-half chance, the whole night could have been much better for his team.
Relatively muted as Dortmund mostly bypassed the centre of midfield and attacked from wide instead. When he did get into the action, simply not as superhuman as usual. Yellow-carded and ineffective.
Picked for his great form but City didn't play to his strengths, with little action out wide and instead focusing on short passes through the middle. The Bosnian must be privately frustrated.
Threatening on the counter for City, the Argentine also displayed some real strength, sometimes holding off as many as four opponents at one time. Didn't get enough service in the second half, though, as Dortmund's defenders started to bully him.
Nearly as impressive between the sticks as Hart. Quite brilliant when rushing out to close down Aguero and made some excellent saves, particularly late to deny Argentine's powerful header. Endured a hairy moment dropping a relatively easy cross in the second half that wasn't punished, though.
The least accurate of Dortmund’s passers when getting forward, as he so often did, but tremendous work rate and width.
One or two awkward touches that could have brought serious punishment in defence but usually followed it up to doggedly win the ball back afterward. Not far away with a chest-down-and-shot in the first half. Very harshly conceded a penalty for an awful handball call - he could hardly have moved.
Never exposed by Aguero as had been occasionally threatened but an awkward fall when trying to get on the end of an attacking set-piece put an end to his night as he went off injured in the second half.
Tireless in his desire to get forward and link up with Blaszczykowski but Nasri did not often offer him much trouble.
Crisp and accurate in his passing - particularly the sublime diagonal that put a chance on a plate for the wayward Lewandowski - but should have provided a bigger test for Joe Hart with a shot late in the first half.
Did not always seem sure who to track as City’s attacking midfielders drifted around the pitch, giving him a real test on his first start of the season, but he improved as the game went on and the hosts' threat proved invisible.
Could perhaps have been more ruthless in his finishing – he was good with the final touch but not great, which allowed Hart’s brilliance to deny him. Superb movement in and around the box, however. His talent is obvious.
Co-operated well with Poland international colleague Piszczek down the right and drilled some powerful crosses towards Lewandowski that just didn’t quite find their man.
A very poor attempted finish with the outside of his boot that should have made it 2-0 was a letdown after plenty of hard work and movement to create space for the dangerous attacking midfielders.
Always switched on, always pressing and always dangerous. Rodwell's error was awful but Reus' seizure of the opportunity was that of a real poacher.
Introduced to bring more penetration down the left but failed to do so as he and City were controlled by a dominant away side.
Shamefully unaware when he weakly passed towards Nastasic, allowing Reus to blitz past the Serbian and finish for the opener. Made the simple passes well enough when in safer positions but cannot afford to switch off as he did.
Always the man you want taking a last-minute penalty and he did not disappoint. His only contribution as a late sub but he made it count. So cool.
