Free-kick to Arsenal in a good position as Toby Alderweireld fouls Alexandre Lacazette. Quite a few Gunners are standing over this.

Brilliant defending by Danny Rose. As Nicolas Pepe heads it back towards goal, Rose rises instinctively.

Spurs defender Danny Rose has put in plenty of good blocks today. And he does brilliantly to head away as Nicolas Pepe's shot from Pierre-Emerick Aubameyang's cross looks goalbound.

BtheG: One thing I am sure of is that we are going to see more goals.

Johnny: David Luiz has to be one of the worst signings in Arsenal's history. He's clueless as a defender and might very well cost them numerous games this season. Utter liability.

Arsenal's bright start is a distant memory now. Alexandre Lacazette is caught offside and looks frustrated.

Mauricio Pochettino said in the past few days that if Christian Eriksen had not left Spurs by this game, then he wouldn't be leaving. The transfer deadline in Spain (and France, Italy and Germany) is tomorrow.

Of the last 14 instances of the away side scoring the opening goal in this fixture, only one has gone on to win (Arsenal in March 2014)

Arsenal look so vulnerable when Arsenal break out. I thought Bernd Leno was at fault for the first goal but that was a wonderful save.

Arsenal have recorded 13 errors leading to goals in the Premier League since the start of last season; the most of any club. Goalkeeper Bernd Leno has more errors than any other player in this period (6).

It's almost 2-0 to Spurs. Arsenal have an attack but can't get a shot away.

The visitors break through Son Heung-min. Harry Kane is in the centre but the pass isn't quite on.

Son goes alone and his shot from just outside the box is tipped over by a diving Bernd Leno.

Does anybody ever use the term 'bragging rights' in any other context than a sporting derby?

J: David Luiz looking like the defender you accidentally switched to while playing FIFA. No idea what he was doing.

Ideozu-Frank: David Luiz beaten too easily there

A Spurs win here could really ignite their season.

Harry Kane controls the ball away from Granit Xhaka, who kicks him. Free-kick.

Spurs had barely been out of their own half until they scored and it was all too easy to cut through David Luiz and Sokratis. Leno should also have done better than push a routine Erik Lamela shot out to Christian Eriksen.

Huge noise coming from the Spurs fans. One corner of Emirates Stadium ecstatic.

That was pretty much Spurs' first attack.

But now the visitors are on top. Christian Eriksen brings the ball forward and blasts in a 20-yard shot which Bernd Leno saves (and holds this time).

Christian Eriksen is the first Danish player to score 50 Premier League goals. He is the first Spurs player to achieve 50 goals and assists in the Premier League.

It's weak defending by Arsenal. David Luiz gets turned too easily and I think Bernd Leno should do better.

He pushes the ball out to Christian Eriksen and Spurs have made the perfect start.

Arsenal have been dominating territory. They've had less of the ball than Spurs - but in all the right places.
