Full-time: Arsenal 1-1 Tottenham Hotspur
All over at the Emirates, then. Both sides will feel they could have won the derby but in the end, a draw feels like a fair result.
Tick-tock, tick-tock... time is ebbing away now. Will someone make themselves a hero on derby day?
Ah, another chance goes begging for Arsenal, as Giroud's headed effort goes straight into the arms of Lloris. Either side, and the Frenchman might have decided the game.
Five minutes of time being added.
The ball is played towards Petr Cech, who appears to slip at the vital moment, before he just regains his footing in time.
Meanwhile, Son has been replaced by young Harry Winks.
Up the other end now, and Giroud is stopped from scoring by a brilliant last-ditch tackle by Jan Vertonghen.
This really has been a thriller, even if the scoreline doesn't suggest that.
Eriksen has struck the post from a freekick on the left touchline!
The Dane drifted the ball into a dangerous area, and it skipped off the turf and off the upright! So, so close for Spurs, who were unable to get a head or a foot on the rebound.
Kieran Trippier is wearing one of those snazzy-looking face masks. It makes him look like he's attending a Halloween party.
Kyle Walker has picked up a knock and is unable to continue. Kieran Trippier is poised to replace the England man.
Just over ten minutes left at the Emirates and there is no sign of either side sitting back. Hector Bellerin, for instance, is playing more like a winger at the moment.
Vincent Janssen, meanwhile, is really struggling to get involved in the game. He looks sluggish, to be frank.
The ball is pinging around the Spurs box after good work from Bellerin, but it somehow falls into the grateful arms of Hugo Lloris. This is really, really tense stuff.
Alexis almost finds Ozil in the box, but the German is just beaten to it by Hugo Lloris. This game has been a really good advert for the Premier League.
Now a Spurs change: Harry Kane's race is run today. He makes way for the under-pressure Vincent Janssen. Time to make a name for himself.
Dier has gone into the book, meanwhile, for running away with the ball after committing a foul.
Arsene Wenger is going to go for this, then. Iwobi and Walcott make way for Giroud and Oxlade-Chamberlain.
The Gunners boss clearly feels this game is there to be won.
Danny Rose has a problem. He's taking his boot off and I'm not sure he'll be able to continue. Kieran Trippier could come on, if the England fullback is unable to play on.
Arsene Wenger must be considering a change here, because the momentum of the game has definitely shifted. Ramsey or Giroud would be my go-to guys if I were the Frenchman.
Yep. Just as I say that, Ramsey has come on for Coquelin. Clearly Wenger is looking for all three points this afternoon.
Harry Kane has missed a guilt-edge chance for the away side!
The ball is played down the left channel, where Danny Rose sends over a gorgeous cross to the England striker, who gets his volley all wrong when he just needed to clip it goalwards. Agonising for Spurs fans.
This has become a brilliant, end-to-end game - with both sides seemingly committed to winning.
Ah, Eriksen almost gives Spurs the lead! The ball drops to the Dane in the box and his effort is brilliantly pushed wide by Petr Cech.
Arsenal are rocking a bit now, though.
GOAL: Arsenal 1-1 Tottenham Hotspur (Kane)
Welcome back, Harry Kane! The striker marks his comeback with an all-important goal for his side, calmly slotting the ball down the middle of the goal.
Penalty to Spurs!
Dembele makes a darting run into the Arsenal box and goes down after being tripped by Laurent Koscielny. A definite penalty, that, and Harry Kane is quick to grab hold of the ball...
Son makes a good early break down the right side, but Hector Bellerin - who is a flyer - comes charging back to clear the danger.
It's noticeable how Mesut Ozil's increased involvement has led to an improvement in Arsenal's general performance. The German is a key player for the Gunners, just in case you didn't already know it.
We' back under way at the Emirates.
There's some debate about the supposed offside on the goal, by the way. On reflection, Alexis Sanchez - who was definitely stood in an offside position - was not interfering with the play.
Replays of the Arsenal goal appeared to suggest that a couple of Gunners players were stood in offside positions when the ball was struck by Mesut Ozil. I'm sure Mauricio Pochettino will have been made aware of that already.
Half-time: Arsenal 1-0 Tottenham Hotspur
A crucial goal just before the break for Arsenal, then, who seized control of the game in the last 25 minutes of the half. The Gunners appear to have sussed out Spurs' tactical changes and were the dominant side by the end.
