If you missed the day's early game, Remi Garde got his Aston Villa career off to a good start with a 0-0 draw against Manchester City.
And in the other 16:00 GMT kick-off it's Liverpool 1-1 Crystal Palace at the break.

Goodness sake Arsenal fans get behind your team. You are joint top of the league coming into this game. Spurs score 1 goal and suddenly lets spend £100M.

That won't be hard John, Arsenal only had one effort in the first half...

"This is a very capable Tottenham side. They have good legs in the middle of the park and the two Belgian centre backs who have excelled. They have clever players and flair. They've done well and impressed me.
"It's a deserved lead. They've been assured and comfortable at the back. I expect Arsenal to be more positive and to have more efforts on goal in the second half."

"It's one of the most accomplished 45 minutes from Spurs I've seen. It's no secret that Tottenham play a high pressing game but this is a very mature performance from Mauricio Pochettino's side."

Harry Kane is the half-time difference maker at the Emirates.
Over to you Arsene.

Almost half time and Arsenal are fading fast. Big changes needed.

Neymar has just scored an absolute gem of a goal for Barcelona. Jamie Vardy-esque.

Spurs looking good as we approach half-time, but they've twice led in the derby at the Emirates in recent years and gone on to lose. Arsene Wenger will not be happy with his team's showing though. Very flat.

Better from Arsenal, as they have their first effort of the day, Alexis Sanchez trying a backheel from Joel Campbell's low driven cross but it's easy for Hugo Lloris.
Before today the longest they had gone this season without a shot on goal was eight minutes.

Here's that Harry Kane goal in graphical form. Perhaps the most impressive feature was the second he gave himself to compose before slotting home. That can be seen in the dotted line in front of the number 10.

Silliness, lots of silliness. First, Olivier Giroud is baulked off the ball and he wants a penalty but nobody saw it. Play on, and Giroud gets up and pushes Jan Vertonghen over. Again, nobody saw it. Giroud needs to calm down or he'll be seeing red here...

"What a ball in from Danny Rose. Where Per Mertesacker is I don't know - he had to get across. Harry Kane is left one-on-one an it's a beautiful finish. He hits it into the ground and it bounces over Petr Cech."

That's five in his last three league starts for Harry Kane after his slow start to the season. You could see the confidence back in him as he waited to take that chance.

Clinical. Absolutely clinical! Danny Rose plays a clever ball over the top, Laurent Koscielny steps up to play offside and Harry Kane is away and onside.
Kane has a lot of time, but he uses it really well. Delays the shot, waits for Petr Cech to move and just glides the shot across the keeper and in.
