Read David Hytner’s report from the Emirates:

Aubameyang talks, after weighing in with his ninth and 10th goals this season. Asked if Arsenal are a different beast under Unai Emery, he replies: “Yeah, I think so. We can see always, we never give up and that’s the mentality. The most important is the present, we are looking to continue this [unbeaten] run. We are still winning games and we just have to keep going.” Victory lifts Arsenal to fourth, above Spurs on goal difference.

Unai Emery celebrates victory in his first north London derby, as his side extend their unbeaten run to 19 matches. Arsenal blew Spurs away in the second half, with Pierre-Emerick Aubameyang adding his second to kickstart the fightback before Alexandre Lacazette stepped off the bench to take the lead. Lucas Torreira wrapped up victory, before Jan Vertonghen was sent off for picking up a second silly yellow card. An incredible game!

90+5 min: “And it’s Arsenal, Arsenal FC, we’re by far the greatest team, the world has ever seen,” is the predictable verse from home supporters. They’re almost there.

90+4 min: Arsenal turn the tempo down to a pedestrian pace, as their fans goad Harry Kane. They’re going to enjoy every single second of this.

90+2 min: Ole! Ole! Ole! Arsenal supporters are enjoying themselves. Agony for Spurs.

90+1 min: Xhaka takes an age to take the corner, soaking applause from almost all quarters of a rocking Emirates. Arsenal don’t bother to send the cavalry up.

90 min: Serge Aurier compounds a tough afternoon with a late challenge on Rob Holding. The Tottenham full-back is booked. Six added minutes to come.

87 min: Xhaka is grounded after a challenge by Winks. The Spurs midfielder yells into the ear of the midfielder, unimpressed at Xhaka milking it. Bellerin gives Winks a shove, and the handbags soon die down, thanks to Mike Dean’s helping hand.

86 min: A timely email. “If Toby Alderweireld had played this game we wouldn’t have let in four goals,” says Alistair Donegan.

85 min: Jan Vertonghen is sent off! It’s a poor challenge, flying in on Lacazette and his day goes from bad to worse. He was booked inside 10 minutes for handball, leading to Aubameyang’s opener and that was always going to earn him his marching orders.

84 min: Eriksen looks to race through on goal, but a roaring Sokratis stops him in his tracks. Arsenal regain possession and waltz forward in search of a fifth.

83 min: Aubameyang almost wriggles away from Foyth, but eventually the Arsenal striker is crowded out. The pocket of Spurs supporters have been silenced.

82 min: Danny Rose replaces Ben Davies.

81 min: Sissoko supplies Davies down the left, and the Tottenham full-back wins a corner. Lucas Moura arrives into the box unmarked, but heads painfully wide.

79 min: Pochettino summons Moura and Winks, in place of Son and Alli. It all feels a little too much, too late. Arsenal wrestled back control and soared through the gears. A shellshocked Vertonghen goes into the book, as Arsenal win another free-kick but Sokratis cannot steer his effort on target.

It’s four – what a game! Lucas Torreira hammers low beyond Lloris from an acute angle. Aubameyang plays a wonderful reverse pass into the Uruguayan midfielder – who has been superb – and he slams it into the far corner. Torreira whips off his shirt in celebration, earning him a booking, but he will not care an inch.

Alexandre Lacazette gives Arsenal the lead, and the Emirates erupts. A few red flares are let off as Lacazette beats Lloris from the edge of the box. It’s a nightmare for Juan Foyth, who is robbed of possession in the buildup. Arsenal then fly forward and after Lacazette spins away from Vertonghen, his low effort squeezes into the corner beyond Lloris, via the shin of Eric Dier. Agony for Spurs. Ecstasy for Arsenal at the Emirates.

72 min: Arsenal are playing more patiently, probing for an opening. Unai Emery’s used all of his substitutes, while Pochettino still has the ability to roll the dice. Lacazette has been lively down the right since coming on, and earns a corner.

70 min: Guendouzi replaces Mustafi, who jogs off, hobbling a little. Arsenal appear to have moved to a midfield diamond, with Xhaka sitting in front of the back four.

69 min: Mustafi’s back up and moving, though Arsenal have Guendouzi ready.

68 min: Bellerin gifts the ball to Son ... but the Spurs striker cannot beat Leno! Bellerin apologises after his attempt to switch play is cut out by Son, who is suddenly plain through on the Arsenal goalkeeper. His effort is powerful, but too close to the German. Meanwhile, Mustafi is grounded with what looks like a leg injury.

66 min: Lacazette’s cross from the right is deflected by Vertonghen. Aubameyang is lurking, but Foyth does superbly to intervene. It doesn’t matter, though, because Aubameyang’s booked for a high boot.

65 min: Alli is booked for clipping the heels of Xhaka. Foyth fouls Aubameyang. The game’s just become a little bitty in midfield, but you sense it’s far from finished.

64 min: Torreira fouls Alli on halfway, allowing Spurs to get things going but Sissoko’s pass is wayward. Pochettino, in the dugout, is a picture of frustration.

62 min: Arsenal break once more, with Lacazette freed in behind the Spurs defence. It comes over to the left, where Kolasinac unselfishly feeds Ramsey, but the Welshman gets it all wrong. Arsenal have very much come out the other end of that testing Spurs spell at the start of this half. Can they finish the job?

61 min: Sokratis heads over from Xhaka’s delivery.

60 min: Arsenal almost, almost find a third! Holding nods across goal from the corner, before Kolasinac sends an effort at goal. Lloris keeps that out but the rebound drops kindly for Torreira, who flashes his shot agonisingly wide. The atmosphere in the Emirates is absolutely electric. And now Arsenal win another corner ...

57 min: Arsenal tails are up. Aubameyang charges down Vertonghen’s pass out from the back, before Kolasinac wins a foul wide on the left flank. Emery’s bouncing up and down the touchline. He’s ushered back towards his dugout.

It’s a superb, instinctive finish! Arsenal fly forward down the right, with Bellerin curling a wonderful ball in for Ramsey, in behind Vertonghen. Ramsey doesn’t have to do a lot to help the ball on but his flick is deft and, first time, Aubameyang lashes the ball beyond Lloris from distance. It’s a wonderful goal.

53 min: Spurs suffocate Arsenal, penning Bellerin in at full-back. But Arsenal wriggle free, only for Holding to ambitiously blast over from distance.

52 min: Arsenal are huffing and puffing. Aubameyang’s adjudged to have fouled Foyth, and Spurs restart. Tottenham will be happy with this.

50 min: Leno palms Kane’s free-kick wide for a corner, but Arsenal eventually clear after Vertonghen did well to recycle the ball. A replay of that corner shows Kolasinac grabbing Foyth by the neck, and then the young Argentine following suit.

49 min: Arsenal gift Spurs another free-kick, this time Xhaka on Alli. Harry Kane fancies his chances. It’s 25 yards from goal, just to the left of the 18-yard box.

48 min: And it’s headed clear by Holding! Eriksen’s delivery is inviting, so much so that Leno comes flying out to punch it away but ends up in no man’s land. Kane cannot get there, either, thankfully. The corner comes to nothing, but Spurs have settled far quicker than they did the first half.

47 min: Kolasinac weighs in with a clumsy challenge on Dele Alli on the touchline. Spurs win a free-kick 25 yards out. Eriksen will swing it in ...

46 min: Lacazette and Ramsey are on for Mkhitaryan and Iwobi. No nonsense from Unai Emery at the break. It could turn out to be a very bleak day for Arsenal at this rate:

A brilliant, if spicy, first 45 minutes. Harry Kane’s penalty gives Spurs the lead at the interval, after Eric Dier equalised at the Emirates. Arsenal dominated the first 20 minutes until Spurs awoke. Dier celebrated by hushing Arsenal supporters and substitutes, warming-up in close proximity. Guendouzi was particularly enraged, Dier booked. Aubameyang gave Unai Emery’s side a deserved lead before Dier nodded in Eriksen’s free-kick and then Son fell under the challenge of Rob Holding, leading Mike Dean to point to the spot. That decision infuriated Kolasinac, who had a little contretemps with Ben Davies. Kane did the rest.

45+2 min: Lloris claws Mustafi’s looping header away from goal! Xhaka whips in the corner, the Arsenal defender connects with it and eventually it bounces off the bar.

45+1 min: Mkhitaryan feeds Aubameyang, but the Arsenal striker cannot get his first touch right. Still, Arsenal win a corner. They play a short, but eventually it’s Dele Alli who clears Tottenham’s lines. Pochettino hastily applauds.

45 min: There will be three added minutes.

44 min: Iwobi plays in Kolasinac, who lays it on a plate for Aubameyang. He must score, but wellies it straight at Lloris. And he’s flagged a yard offside anyway.

43 min: Arsenal enjoy some possession, with Eriksen pulled up for a foul on Bellerin. Arsenal will break through Iwobi ...

41 min: Alli looks to play in Kane from the right, but Sokratis clears. And Leno is moaning about being clobbered by the Spurs striker. Aurier throws in from the right as Spurs look to up the ante.

39 min: Spurs are enjoying themselves, playing little triangles around a sea of fuming Arsenal shirts. Temperatures are simmering, though Arsenal need to be wary they don’t boil over as Xhaka gets himself in a tangle. Bellerin slams the ball down after Iwobi overhits a dreadful crossfield pass in search of the full-back.

37 min: A plucky challenge by Mustafi on Son earns the Germany defender a booking. That, equally, had been coming. Spurs are in the ascendency.

35 min: Spurs have the bit between their teeth. Arsenal appear to have imploded, with the occasion suddenly overwhelming them. Mustafi is the latest player guilty of a silly foul on halfway. Emery desperately wants his players to calm things down.

Harry Kane strikes. That’s his eighth goal against Arsenal in eight games. Emery is scratching his chin, unnerved at what’s just unfolded before his eyes.

33 min: And now Spurs have a penalty! Son had made a brilliant run, and Holding scythes him down. Arsenal are suddenly on the back foot.

View image in fullscreen

31 min: Hang on a minute, Pochettino is down by the corner flag as Spurs players and Arsenal substitutes have a little ding-dong. Dier wheels away to celebrate in front of a section of Arsenal supporters, where the substitutes are warming up, and it’s pretty unsavoury, if relatively low-key. Pochettino, meanwhile, is reminded by the fourth official Andre Marriner that his technical area does not stretch 40 yards.

Spurs restore parity, with Dier nodding in Eriksen’s free-kick at the front post. Bernd Leno hardly covered himself in glory, with the ball squeezing in at his near post.
