Kelly Cates presides over the draw in the tunnel at Ashton Gate, aided her glamourous assistants Phil Neville and Lewis Carey. “Phil, give the balls a good rummage,” she says, prompting no end of schoolboy sniggering from the assembled onlookers.

Asked what his thoughts are: “My thoughts are they were a bit lucky, but they fought hard to be lucky,” he says of Bristol City’s win. “They win the game in the moment when everyone was waiting for our goal. But also we hit the post twice in the first half., But they played brilliantly and fought like it was the biggest night of their lives and it probably was. It’s a beautiful game for football. I don’t want me saying they were lucky to be the most important thing. The most important thing is that a team from the Championship beat Manchester United. In the first half we lacked intensity. And when I say intensity I mean not just physically but mentally. For some of us it was like one more day in the office, probably a day for some of them where they don’t even want to come to the office. For the Bristol boys it was a big, big day for them, and you could see that.”

Ben Fisher was present for the Guardian on one of the more famous night’s in the history of Ashton Gate.

Korey Smith speaks: “Absolutely unbelievable,” he says. “The lads have played brilliantly. I don’t score a lot, but as you can see the lads are very happy. I said to the boys at half-time, if I make the run try to pick me out and Joe played me in.”

Korey Smith is in big demand: The Bristol City match-winner is posing for selfies with hundreds and hundreds of Bristol City fans and looks exhausted, but is now being helped towards the dressing room by some stewards. That was a great game of football and City are worthy winners. Stay tuned for the semi-final draw, in which City will be paired with Manchester City, Arsenal or Chelsea. They’ve already knocked out four Premier League teams, who’s to say they won’t beat another.

It’s all over! There’s a pitch invasion as Bristol City’s fans run on to the field to swamp their exhausted players at the end of a wonderful Cup upset. Bristol took the lead early in the second half courtesy of a Joe Bryan howitzer, only for Zlatan Ibrahimovic to equalise with a free-kick a few minutes later. On the rack and under immense pressure, Bristol City kept on keeping on and with the game looking certain to go to extra time, up popped Korey Smith at the death to nick a late, late winner for the Championship side.

Incredible scenes at Ashton Gate! Working tirelessly at the knockings of normal time, Korey Smith puts Bristol City 2-1 up against Manchester United, ghosting in behind the defence to pick up a dinked pass over the top from Joe Bryan and control and volley the ball past the hopelessly exposed Romero from four yards out.

Would you believe it?!?!?!?!? Bristol City have almost certainly snatched it at the death.

90+3 min: United get forward again, but Lukaku’s shot from inside the Bristol City area is blocked. Now it’s the home side’s turn to attack on the break, but a poor delivery from Niclas Eliasson lets them down.

89 min: Aden Flint wins a free-kick for Bristol City not too far inside the Manchester United half. Marlon Pack lofts the ball forward and United clear. With United breaking on the counter, Matt Taylor brings down Romelu Lukaku and gets booked. Paul Pogba picks up a yellow card too, after mouthing off at referee Mike Dean for something or other.

87 min: Victor Lindelof looks to have sold Sergio Romero short with a back-pass, but there’s just enough on it to enable the United goalkeeper to hoof the ball clear under pressure from Bobby Reid.

87 min: We approach the end of normal time, with Manchester United turning the screw on Bristol City, but unable to find a way through on goal.

83 min: Chelsea have beaten Bournemouth and go into the Carabao Cup semi-final draw along with Arsenal and Manchester City. Back at Ashton Gate, Luke Steele saves brilliantly from Lukaku’s low drive, getting down quickly to scramble the goal-bound effort clear for a corner.

80 min: Great play from City, who go close as Marlon Pack has a cross deflected over the bar for a corner, which results in the ball being sent sailing straight into the arms of Romero.

79 min: For Bristol City, Jamie Paterson cuts inside Matteo Darmian and sends a shot curling wide of the Manchester United goal.

Meanwhile at Stamford Bridge: Dan Gosling has equalised for Bournemouth against Chelsea in the 90th minute ... only for Alvaro Morata to nick what looks likely to be a very late winner for the hosts.

77 min: Another corner for Manchester United, which is cleared by a meaty header from Aden Flint.

76 min: Great goalkeeping from Luke Steele, who does well to tip a Lukaku header around the upright and out for a corner, from which nothing comes. Bristol City are under immense pressure here.

75 min: Bristol City substitution: Josh Brownhill off, Niclas Eliasson on.

74 min: Marcus Rashford gets a yellow card for a late challenge on Joe Bryan, moments after putting Bryan had put in a wonderful, potentially match-saving covering tackle on the Manchester United striker who looked through on goal with an unmarked Lukaku up in support to his right.

73 min: Bristol City win a free-kick just inside the Manchester United half. Bryan floats the ball forward, but Marcos Rojo clears.

71 min: United advance into Bristol City territory with Lukaku and Mkhitarian linking up well. With Rashford calling for the ball, Lukaku opts to shoot himself but doesn’t trouble Luke Steele unduly with his effort.

68 min: There’s a pause in play as Josh Brownhill receives treatment down by one of the corner flags. Manchester United substitution: Zlatan Ibrahimovic off, Henrikh Mkhitaryan on.Bristol City substitution: HOrder Magnusson off, Matt Taylor on.

66 min: Bristol City’s defence are being pinned further and further back by a Manchester United team that seem to have the smell of blood in their nostrils. Bristol City win another throw-in deep in United territory, which Magnusson takes long again. Romero comes for the ball and misses it, but Aden Flint sends his header floating agonisingly wise of the upright.

63 min: Replays of Zlatan’s free-kick show that he took advantage of a gap in the Bristol City wall and the ball took a slight deflection off the back of Korey Smith on it’s way in. I suspect Luke Steele would have beaten anyway, as he was completely unsighted.

60 min: Manchester United substitution: Romelu Lukaku on for Daley Blind. A striker for a holding midfielder - Joe wants to put this one to bed as quickly as possible and as entertaining a game as it is, for that we should all be thankful.

Zlatan equalises with the free-kick. He blasts a shot through the wall and into the bottom right-hand corner. Bristol City’s lead was short-lived, but Manchester United have equalised from a free-kick they were very lucky to get from Mike Dean. It was a good shot from the has-been, though. Write him off at your peril.

57 min: Manchester United win a free-kick in a good position just to left of the day for a Korey Smith “foul” on Paul Pogba, who appeared to just run into the midfielder.

55 min: With their tails up, Bristol City carve out another shooting opportunity courtesy of a nice dummy from Bobby Reid that allows the ball to run to Joe Bryan again. This time he shoots from the edge of the area on his weaker right foot, but his low daisy-cutter doesn’t trouble Romero unduly.

53 min: That was a brilliant finish to an excellent move that began and ended with Joe Bryan. He played the ball forward, kept on running up the inside left channel past two or three Manchester United players, picked up a pass from Marlon Pack and blasted the ball past Romero. Bristol City lead and you can’t say they don’t deserve it.

Bristol City take the lead! Joe Bryan sends a diagonal surface to air screamer fizzing across the bows of Eduardo Romero and inside the far upright.

50 min: Bobby Reid gets a yard on Victor Lindelof in the United 18-yard box and shoots into the side-netting from a narrow angle.

48 min: Another free-kick for Manchester United in much the same position for a Josh Bronhill foul on Anthony Martial. This time the one-man wall, Korey Smith, almost diverts the ball into his own net, but Luke Steele recovers well to save his team-mate the embarrassment of what might have been a hideous own goal.

46 min: Jamie Paterson gets the first yellow card of the evening for a late challenge on Paul Pogba. Free-kick for Manchester United wide on the left, about 35 yards from the Bristol City goal. Ibrahimovic runs over the ball and Rashford blasts a low drive into the one-man wall.

46 min: Play resumes with Manchester United getting the ball rolling. With Arsenal and Manchester City already in the Carabao tombola for the semi-final draw immediately after tonight’s game, Chelsea currently lead Bournemouth in the other quarter-final being played this evening. There are no changes in personnel on either side at Ashton Gate.

Peep! Mike Dean blows for half-time and both sets of players march in after a thoroughly entertaining 45 minutes of play. Bristol City boss Lee Johnson will be the happier of the two managers so far - his team have acquitted themselves very well so far and have been brave in their attempts to take the game to Manchester United.

44 min: Another long throw from Magnusson, who hurls the ball straight into the arms of Romero.

41 min: Daley Blind dives in to take the ball off the foot of Korey Smith in the Manchester United penalty area when the midfielder was clean through on goal and dithering over a shot. Brilliant play from Bristol City to get in behind the United defence after catching them napping with a quick throw-in. Smith shouldn’t have given Blind the opportunity to save United’s bacon with a last-ditch tackle after finding himself through on goal.

40 min: Daley Blind sends the ball into the mixer, Mctominay gets his head to it and the ball drops for Zlatan Ibrahimovic who volleys high over the bar from a tight angle under pressure from Josh Brownhill.
