Read David Hytner’s match report from the Emirates Stadium:

Peep peep! That was a spectacular, ceaselessly entertaining game of football. Arsenal will feel that in a parallel universe they are celebrating a 5-3 victory. Paul Pogba was sent off, Anthony Martial produced one of the flicks of the season, Arsenal played attacking football of the highest class, David De Gea made some astonishing saves... I don’t know where to stop. It was a glorious match.

United have ended Arsenal’s long winning run at the Emirates and move to within five points of Manchester City, who have a tricky match at home to West Ham tomorrow. Thanks for your company, sorry I didn’t get much chance to look at the emails. Night!

90+3 min Marcus Rashford replaces Ashley Young, who has had a fine game.

90+2 min Ozil’s volleyed cross is spanked into orbit by Ramsey, 10 yards from goal. It was a tricky chance on the turn and he got under it.

90+1 min Five minutes of added time.

90 min Arsenal have another penalty when Smalling slides through Lacazette. There was less in that and Andre Marriner wasn’t interested.

89 min Sanchez and Herrera are booked for a physical exchange of unpleasantries.

88 min Welbeck goes over after a challenge in the area from Darmian. That was a clear foul and should have been a penalty. Welbeck didn’t help himself by getting straight to his feet. I think the referee thought Welbeck slipped, but replays confirmed there was clear contact as he turned back inside Darmian on the right of the area.

87 min Lukaku bursts past the last man Koscielny, who drags him down and is booked. The distance from goal - 45 yards - saved Koscielny from a red card, though Mourinho is furious. I think it was the right decision.

84 min Ramsey’s cross from a narrow position is headed over by Welbeck. It wasn’t much of a chance. United, down to 10 men, look more comfortable defensively than at any stage in the match. I suppose it helps the defenders know they have an utter genius behind them. I’ve never seen a goalkeeper with better reflexes, and boy have I seen some goalkeepers.

83 min Welbeck’s deflected long-range shot is tipped over by De Gea, a comfortable save. Arsenal haven’t created much in the last 20 minutes. There’s an argument they have too many cooks - Lacazette, Giroud, Sanchez, Welbeck, Ozil, Iwobi, Henry, Bergkamp, Groves, Hayes, Diawara.

82 min Arsene Wenger is complaining, presumably about timewasting, to the fourth official. This will be a sore one for him if he loses again to Mourinho, especially as his team have played some glorious attacking football.

81 min United should get Rashford on for the lone midfielder/attacker Lukaku, who looks shattered. They can’t get out at all. I think this will end 3-3 you know.

80 min We have exclusive highlights of the first 80 minutes of this match.

78 min Tacticswatch: Arsenal are playing 2-0-8, United have gone for an 8-0-1.

77 min Arsenal bring on another forward, Olivier Giroud, in place of Kolasinac.

76 min Matteo Darmian replaces Jesse Lingard.

75 min That means Pogba will miss the Manchester City game.

74 min Paul Pogba lunges at Bellerin and gets a straight red card! Pogba applauds sarcastically but he shouldn’t argue - he put his studs on the ball and then followed through onto Bellerin’s calf. I’m not certain there was malicious intent but his studs went over the ball and that usually means trouble. That said, this MBM is so frenetic that I haven’t had chance to look at it properly, so for all I know he may have set about Bellerin with a crowbar.

73 min De Gea hasn’t made a save for seven minutes. Wenger out!

72 min Bellerin is booked for a dismal tackle on Young.

71 min “Regardless of the result, I’d say this is the best Arsenal have played in around ten years,” says Andrew Hurley. I know what you mean, certainly going forward. Their defending has been pretty shoddy though.

70 min Arsenal make a change, with Danny Welbeck replacing Granit Xhaka. Arsenal’s formation is now a vague 4-1-5.

68 min “It’s only fair to point out how brilliantly officiated this game has been,” says Phil Harrison. “So rarely gets said in reference to great games.”

Yes, good point. It has really flowed and that’s in part down to the referee.

67 min United make a defensive substitution: Ander Herrera replaces Anthony Martial, who had a quiet second half after being the best player in the history of football before half-time.

66 min Sanchez’s stinging long-range shot is pushed away by De Gea, diving to his right. I can’t keep up with this. De Gea has made enough saves for two or three months.

The move started when Matic played the ball up to Lukaku on the halfway line. He fed it to Lingard, who surged into space and played the ball to Pogba on the right. He moved into the area and danced elegantly around Koscielny, who commited himself unnecessarily, before passing the ball across the face of goal for Lingard to tap into an open net. It was another clinical break from United, though Arsenal’s defending was again less hope.

United sting Arsenal again on the break!

62 min This game has been so breathlessly end-to-end that it may have introduced the concept of the counter-counter-counter attack.

61 min The BT Sport chaps, Glenn Hoddle and Steve McManaman, reckon Ramsey miscontrolled the ball for Lacazette’s goal. I suspect they’re right. It’s a shame because it would have been an ingenious, counter-intuitive touch.

60 min Matic has a clash of heads with Koscielny, which gives United a bit of a breather.

58 min Rojo is ooked for manhandling Sanchez. The United defenders cannot get a moment’s peace.

56 min David De Gea makes a sensational double save to deny Lacazette and Sanchez. The first was a brilliant, sharp stop as he plunged to his right, and although he couldn’t get to his feet for the rebound he thrust out his right foot to block Sanchez’s close-range follow-up. De Gea is a genius in any language. The first save was so good.

55 min Both teams have parked the bus - but they’ve done so at the wrong end. The match has been so open from the first minute.

53 min The game lurches to the other end, where Iwobi drills a low shot that is pushed away by the diving De Gea.

52 min Lingard hits the post! This game is turning into an all-time classic. He was put through on goal and hit a shot that was saved by the outstretched right arm of Cech. The ball looped behind him and bounced up onto the far post before Martial’s close-range follow-up hit the back of Monreal on the line.

Sanchez, on the edge of the area, clipped an excellent pass over a number of defenders to meet Ramsey’s late run. He was clear on De Gea but cushioned the ball backwards to Lacazette, who slammed it into the net. I think Ramsey meant it, and if he did it was a remarkable touch because he was six yards from goal. He may just have miscontrolled it.

It’s on!

48 min The second half has started as the first ended, with Arsenal on the attack. United have been unusually ragged defensively, although, as Andrew Hurley points out, much of that is down to Arsenal’s tempo.

47 min “Hugely enjoying this even though I don’t know what I want the result to be,” says Ian Copestake. “Never mind tactics and entertainment and that, I probably think this match is about me.”

46 min Peep peep! United begin the second half. They may well need another goal to win this game.

Half-time Kant

“Charles Antaki’s email inspires a few philosophical comparisons,” says Klaus Yuri Møller-Arentoft. “Sunderland are 7 years into re-enacting Kant’s Critique of Judgement. One of the earliest Bielsistas was Hannah Arendt with The Human Condition. Liverpool’s Premier League era is best described in Nietzsche’s essay On the Advantage and Disadvantage of History for Life.”

Where does Peter Reid’s Premier Passions fit into this? (Warning: video contains locker-room language, etc.)

“Martial best player on the pitch?” sniffs Andrew Hurley. “Sorry, but you need to leave your United hat off. It’s all Arsenal, who have been brilliant since ten minutes.”

I don’t have a United hat. I just have a football hat. I just want football to be winner - and so far it has been!!

That was absolutely brilliant entertainment. A clinical United punished two bad defensive errors early on and were a constant threat on the break, yet for most of the half they were pummelled by Arsenal. This could be any score. I don’t mean at the end of the game, it could be any score now. See you in 10 minutes for the second half.

45+2 min It’s mayhem in the United area! De Gea makes a sensational reflex save to stop Lukaku scoring an own goal. That leads to an almighty scrum that seems to go on forever until Lacazette’s shot is blocked by a defender.

44 min Bellerin hits a fierce rising drive from 25 yards that is pushed away dramatically by De Gea, diving to his right. Moments later, Kolasinac smacks a bouncing shot towards the near post that is again palmed away by the sprawling De Gea.

43 min Martial, the best player on the pitch in this half,. beats Xhaka with ease and teases a dangerous deep cross towards Lukaku. Monreal gets in front of him to head clear.

42 min A loose ball breaks for Ramsey, who smacks a low shot that is brilliantly blocked by the stretching Matic. That looked a certain goal. This is such an entertaining match. Arsenal could easily be 4-2 up or 4-0 down.
