- Pep Guardiola's side maintain 100% start to the season with win at Old Trafford.
- Kevin de Bruyne and Kelechi Iheancho put City ahead after dominant opening 40 minutes.
- Zlatan Ibrahimovic pulled one back in final minutes of the first-half after Claudio Bravo error.
Uniteds 100% start to the season is over, City's continues. Pep Guardiola has drawn first blood against Jose Mourinho in Manchester and his side move clear at the top of the Premier League.
A sublime first 40 minutes from the away side, masterminded by the excellent Kevin de Bruyne, proved to be the difference. United pushed and pushed in the second half after Zlatan Ibrahimovic pulled one back, but on balance, it is a derseved three points for City.
Full-time: Manchester United 1-2 Manchester City
Ibrahimovic lashes another half volley on goal that has Bravo wrong footed, but a deflection takes it just wide. United launch the corner in, but Bravo is fouled. Mourinho is running out of time.
Five minutes of added time come up on the board.
Two minutes of the 90 left. Both sides are, for the lack of a better term, absolutely knackered.
Remember earlier I said Ibrahimovic was booked for the most blatant trip you'll see all season? Scratch that, Rooney has just topped it. Bravo (under pressure again) opts to try and turn the onrushing Rooney, managing it but has his ankles clipped for his trouble. It's a stupid challenge from the United skipper who perhaps should have been shown a yellow earlier in this contest.
Shaw comes off for Martial. Safe to say, Mourinho is going for this.
Anthony Martial is coming on.
United are screaming for a free kick when Bailly is felled on the edge of the D and then scream for a penalty when Rooney drives a cross in from the right that comes off Sagna. Mark Clatternburg waves play on however and City spring forward. It's sublime from De Bruyne, who cuts in from the right and drives a low effort towards the near post. Unbelievably, it comes off the inside of the post and rolls across the face of the goal before it is hacked away. This is chaos.
Rashford finds the back of the net! But it won't count! As we've seen so many times from the 18-year-old already, he cuts in menacingly from the inside left channel before opening room for the shot. His effort takes a deflection off Ibrahimovic who has wandered into the an offside position, guiding it into the far corner and it's a good shout from the linesman.
Great chance for Ibrahimovic. Fellaini does well to beat his man in the air and knock it down to the Swede who takes the half volley on from the edge of the box. It's an awfully difficult effort to take on, but you fancied him to do better with that.
Leroy Sane meanwhile has come on for his City debut, he's replaced Raheem Sterling, who has had a pretty quiet afternoon.
Oh dear, Bravo. Instead of clearing the ball, he opts to turn Ibrahimovic who is closing in on him. His touch is heavy, and it invites Rooney to close in on the loose ball too and in a bid to get their first, Bravo leaps in. It's a poor challenge and you feel if it took place anywhere else on the pitch, it would have been a foul and at least a yellow card.
That change from Guardiola has been City regain a foothold in this contest. They've slowed the game down considerably and have the ball back again.
Moments before that Fellaini was shown a harsh yellow card after Kolarov appeared to run into his arm.
Guardiola is making a change with his side under increasing pressure; Iheanacho comes off for the more sturdier presence of Fernando.
Ibrahimovic is shown a yellow card for the most blatant trip you will see this season on Otamendi.
United are playing with a relentless pace at the moment, City are being given no time on the ball.
Ibrahimovic, under pressure from Stones, takes a cross down on his chest before trying another half volley but he fires over. United have come out for this second half swinging.
Instant impact from Rashford. Out on the left, he turns Sagna with ease and bursts down the wing before dinking a ball into the box with Pogba and Ibrahimovic lurking but the latter fires over.
The second half is about to get underway and Jose Mourinho is making two changes; Ander Herrera and Marcus Rashford are on, Jesse Lingard and Henrikh Mkhitaryan come off.
Half-time: Manchester United 1-2 Manchester City
United have a chance for an equaliser! A mix-up at the back, again involving Bravo gives Ibrahimovic the chance to prod another effort on target but it is hacked off the line.
United have one back! Claudio Bravo comes out to retrieve a fine cross from the right, but under pressure from his own man John Stones, the Chilean spills the ball and Ibrahimovic brilliantly punishes the away side, accurately finding the far corner with a half volley.
