That was good football from Arsenal there, really intricate play in the middle of the pitch. But they're leaving a lot of open space in behind, and that space is there for the likes of Dele Alli and Son Heung-min to exploit.

Spurs are unbeaten in 11 games in all competitions and have their noses in front now. Harry Kane has been the difference maker once again but could really have had at least three goals this afternoon. Will Arsenal make him pay for his rare profligacy?

Half an hour to go.

Spurs are third, Arsenal sixth in the as it stands table. The home side have been much the better side in the second period.

Ben: As an arsenal fan, I can't wait for the world cup where i'll be able to support Harry Kane. He is frighteningly good up top.

It's a big left hand from Petr Cech, he's used all his experience there to get across. That was heading right in the top corner from Christian Eriksen.

Petr Cech's wait for a 200th Premier League clean sheet goes on - but that's a magnificent save! Full stretch to claw away Christian Eriksen's free-kick.

Harry Kane has seven goals in seven Premier League north London derby games - only Emmanuel Adebayor has scored more (8).

Doctor Joker: Harry Kane always turns up at the North London derby, he's an impact player. Absolutely world class.

The game should open up now. Whether Arsenal will take off Xhaka or Elneny, we'll see. I just feel that the midfield of Ozil and Mkhitaryan playing with Wilshere, creative as it is they don't move enough.

If anything he's hit that too well...

Harry Kane middles a volley from a cross from the right, it's sweet as a nut but right down the throat of Petr Cech and he's able to beat it clear. Lovely connection though, Arsenal on the rack.

Dave W: Arsenal obviously aren't going to beat Kane in the air eight yards from goal - they should do better stopping the ball coming in from out wide.

Kwasi: Hopefully this game can come to life now.

Harry Kane hasn't got as good contact on that one, he'll be disappointed he hasn't got that on target. You can hardly hear yourself inside the stadium now!

Wembley is echoing to the chant of "Harry Kane - He's One Of Our Own" after that superb soaring header. Spurs had already slipped into an extra gear even before that goal. So frustrating for Arsenal after they have been defending with such discipline.

Should be two! Harry Kane could well have had a hat-trick today in fact as he steers another clear header wide.

What a chance that is, he's only six yards out and puts it wide. Big let off for the Arsenal.

What a goal! It's a brilliant cross, and a great start from Spurs in this second half. Harry Kane has towered above Laurent Koscielny and his header's skipped off the turf into the bottom corner. But what a super cross from Ben Davies.

Petr Cech takes on Harry Kane with the ball at his feet and gets away with it! That was an interesting call. Arsenal then look to break but Mousa Dembele sweeps the ball away from Mesut Ozil superbly.

Straight away Spurs get the ball into the Arsenal area through Son, he plays in Ben Davies on the overlap but his low cross is turned away for a corner.

We are back up and running.

Robert: It looks like Spurs are targeting Arsenal's right side. They must think Hector Bellerin or Mesut Ozil have mistake in them.

Chris: It’s days like this I love being a Liverpool fan. Thrillers against Spurs, Arsenal and Mann City. This is just insipid.
