Ball breaks kindly to the Spurs captain on the edge of the box, and he expertly guides the volley into the corner of the net. Superb finish. A ninth goal in a North London derby from Son Heung-Min.
Taking so many chances with their passing at the back, but almost open the door at the other end as Raya makes his first stop of the night from a Dejan Kulusevski finish only six yards out. Better from Tottenham.
Out of nowhere, Tottenham almost stun the home side with their first attack of the day. Gabriel with a superb last-ditch diving tackle to win the ball ahead of Solanke from a brilliant run and cross by Djed Spence.
All one-way traffic in this North London derby battle as Trossard is penalised for a late clip on Porro to take the strain off Spurs for a few seconds.
Odegaard drops a decent free-kick into the heart of the Tottenham box, but Kinsky is off his line to punch clear as an offside flag is raised. The Spurs keeper is then almost robbed by Havertz before landing on the ball. So fortunate there.
But this time his cross is behind Havertz and the under-siege Spurs defence can wallop clear the latest Arsenal raid. Still 0-0 with Arsenal up to 29 passes in the final third. Which says it all.
Martin Ødegaard driving in another fine ball with plenty of whip and direction, but Kinsky does enough to claw that delivery behind his goal. Arsenal winning a series of set-pieces and corners. Spurs keeper again deals well with the Rice corner.
This time Odegaard plays in Sterling with a fine little pass, but the cutback across the box is cut out by Archie Gray for another Arsenal corner. Porro does some excellent covering work seconds later to stop the ball entering the Spurs penalty area.
Emirates goes a bit quiet every time Spurs are on the ball. Arsenal looking to apply the high press in the visiting box, and Tottenham end up knocking the ball out of play. Much to the delight of the home support.
Spurs coughing up the ball around the halfway line. Raheem Sterling seemed to take the ball beyond Kinsky, but Gray does well to track the run and do the covering work before Sterling lost his footing. Decent chance not taken. Rice then overcooks a corner to the back post as ball flies straight out of play.
Spurs in changed strips, a light blue striped number, for this trip to the Emirates. Rice with an excellent early free-kick straight into the Tottenham box, but the visitors do enough to clear the danger. Looking to ease themselves into this contest.
What a night at the Emirates. Can't beat a North London derby match in January. Arsenal fans in full voice. Looks a lovely night for football too. Spurs get the action moving.

It is only the England player's third league start for the Gunners and he is the fifth player to start on the right wing since Bukayo Saka picked up his hamstring injury at Fulham last month. Sterling came off the bench against Manchester United on Sunday.
"I was really happy with the way he came in" said Arsenal manager Mikel Arteta. "Since he had the injury and he came back, you could sense he was going to give us something important.
"Great, because we need him. You see what he can bring. He is used to playing in this kind of context and the demands that we have, every three days. Great to have him."
