Harry Kane returned from injury to earn Tottenham a 1-1 draw against Arsenal in the Premier League on Sunday.
After Theo Walcott had hit the post with a superb effort, Arsenal took the lead through Kevin Wimmer's own goal just before the break, the defender heading past Hugo Lloris from Mesut Ozil's cross.
Back in the side after a seven-week absence, Kane's penalty levelled it up for Spurs after the break, following Laurent Koscielny's foul on Mousa Dembele.
The result means Tottenham are still the only unbeaten side left in the Premier League, but stay three points behind Arsenal.
Kane started for Spurs after being out with an ankle ligament injury, but Dele Alli missed out having picked up a knee problem in training on Saturday.
The England international nearly returned with a bang after 21 minutes, steering a diving header from Christian Eriksen's cross just wide of Petr Cech's right-hand post.
Arsenal woke up as the first half wore on, and Alex Iwobi should have done better when put through by Alexis Sanchez, but his low effort was collected by Lloris.
Walcott was denied a stunning opener as his fierce effort from just outside the area bounced off the woodwork, before Ozil blazed the rebound over the bar on the half volley.
Arsenal took the lead three minutes before half-time as Ozil's free-kick was diverted by Wimmer's head into his own goal, though the replays showed that Sanchez, who did not touch the ball but was arguably involved in play, was offside from the German's cross.
Spurs improved after the break, and levelled from the spot through Kane after Koscielny had brought down Dembele following a fine run from the Belgian.
Kane stepped up, slotted the ball down the middle of the goal, and celebrated his fifth goal in a north London derby, and his 14 in 14 games against other clubs from the capital.
Petr Cech kept the scores level just five minutes later, superbly diverting Eriksen's firm left-footed effort from 12 yards wide of the post, before Kane failed to divert at the far post after Danny Rose had picked him out.
The unmarked Granit Xhaka was then inches away from converting a Sanchez cross, while Eric Dier did superbly to block Hector Bellerin's shot from close range.
Eriksen hit the post with six minutes remaining after a deep cross from the left byline went through the crowd in the penalty area, and in the 90th minute substitute Olivier Giroud failed to test Lloris with an unmarked header.
Spurs are now without a win at the Emirates since November 2010, while four of the last five north London derbies in the Premier League have ended in a draw.
