This has all gone very badly against Arsenal now. The Gunners had started to become very frantic when they were one goal down, then had Rob Holding sent off and now face the toughest of tasks after Harry Kane's second.

Spurs are rampant and the stadium is rocking.

Handsome Nick: This game has been ruined by the referee. Soft penalty. Ridiculous decision to give a second yellow for a player standing their ground. It started as a great even battle but Paul Tierney has completely ruined this match as a contest. Mike Riley would be proud.

Harry Kane hounds down Aaron Ramsdale but he keeps his cool, nudging it past him and passing it left to Gabriel.

Emerson Royal can't quite bring down a long ball in the Arsenal box. It's kept alive by Dejan Kulusevski but the flag is up for offside anyway.

It is a reverse of the earlier fixture of the season when Arsenal made a strong start, this time it is Tottenham and it is that man Harry Kane again. Predatory.

I am looking at Antonio Conte, totally animated, celebrating with his staff. What a start for Tottenham.

Mwamburi: Hands up if you didn't see a Rob Holding Red card after the first yellow. He was always going to be targeted once Son had his number. Arteta's naivety there not hooking him off. Game done and dusted.

Sam Hartles: Rob Holding hang your head in shame. What a silly boy. Arsenal have lost all composure and discipline

The Arsenal staff are still in deep conversations. Mikel Arteta is shaking his head while listening. Ben White is being given instructions and might be coming on.

Harry Kane chips a clever free-kick over the top for Ryan Sessegnon. He tries to pull it back first time but gets the ball stuck under his feet and Arsenal are able to clear.

Rob Holding has just landed his team in a load of trouble. He is not focused on the ball, he is totally focused only on Son. Even though you would say that is him trying to rattle Son it has gone the other way, Son has rattled him.

It has been too much from Holding and he has been sent off.

Mikel Arteta looks shell-shocked. He's in discussion with his staff on where to change things.

Uh-oh. He's off. It's been coming.

Rob Holding, who was already on a booking, sticks an elbow in Son Heung-min's face as Eric Dier plays a long ball for him to chase.

It's very, very silly. A second yellow. Arsenal are down to 10 men and a goal behind.

Arsenal are dropping off a bit. They started pressing really high but Spurs are starting to hurt them a bit getting in behind.

It's given away by Arsenal again. Dejan Kulusevski finds Harry Kane, who lays it off to Son Heung-min but he loses it.

Harry Kane is looking very lively now!

Rodrigo Bentancur is played in down the right. He curls it across the six-yard area and Kane is looking for the touch.

Cedric Soares does well to slide in before he can connect. He HAD to time that right and did.

Paul: If that’s a penalty, and I’m not saying whether it should or shouldn’t be, but if it is then you’ll be getting penalties in every single game without fail for the same thing. See things like that often that just don’t get given.

Andrew Mitchell: Son’s taken full advantage of it, but Soares was the wrong side and knew he wasn’t getting to the ball. You’re not going to get away with pushing a guy in the back as he jumps for a header.

Spurs fans are enjoying themselves now. Their side have got a bit about them at the moment. Bukayo Saka loses out to Ryan Sessegnon on the byline and gets jeers from the home supporters.

Granit Xhaka then launches one way over from outside the box.

What a chance!

Cedric Soares gives it away. Son Heung-min links up with Harry Kane. He nutmegs the first defender then goes past Takehiro Tomiyasu but the Arsenal full-back recovers to make an excellent block.

From the rebound, Emerson Royal blasts it over the bar.

Rob Holding is in the book for a third foul on Son Heung-min. He's been nibbling at him all game so far. He needs to be careful!

Smoke rising from both ends of the Tottenham Hotspur Stadium as the flares go off. Harry Kane was never missing that penalty.

Wall of noise inside here as the home side break the deadlock.
