Arsenal's Pierre-Emerick Aubameyang missed a 90th-minute penalty as a scrappy north-London derby against Tottenham Hotspur ended in a 1-1 draw on Saturday.
Hugo Lloris got down low to keep out the substitute's poor kick and rescue a below-par Tottenham who had equalised in the 74th minute through Harry Kane's spot-kick.
Arsenal, bidding to close the gap to their arch-rivals to one point, had taken the lead in the 16th minute when Aaron Ramsey broke clear after a mistake by Davinson Sanchez.
Kane had a first-half header ruled out for offside but Tottenham struggled to create chances as a third Premier League defeat in succession for the first time since 2012 loomed.
Alexandre Lacazette had wasted a good chance to make it 2-0 to Arsenal, but it was the man who replaced him, Aubameyang, who cost his side victory with a poorly-struck penalty after Sanchez was adjudged to have fouled him.
A niggly game ended with Arsenal's other substitute Lucas Torreira being red-carded for a high tackle on Danny Rose.
Tottenham's first league draw of the season left them third in the table, four points above Arsenal who can be overtaken by Manchester United if they beat Southampton later.

Harry Kane loves a London derby, and the Tottenham striker would move ahead of Emmanuel Adebayor as top goalscorer in this fixture in the Premier League should he get on the scoresheet today.
Kick-off is less than 20 minutes away...
Kick-off is very swiftly approaching.
Spurs, of course, are yet to draw a game in the Premier League this season...
Tottenham are assembled in the tunnel, but Unai Emery and Arsenal are making them wait, delaying their exit from the Wembley dressing rooms to as late as possible.
Mind games...
Finally the teams come out onto a Wembley pitch swathed in March sunshine, somewhat overcast morning skies clearing to leave perfect conditions for spring football.
Scarcely an empty seat in the lower tiers, and it's hardly sparse at the very top, as you would expect.
Anthony Taylor is the whistle man for this fixture.
1 minute
As anticipated, Shkodran Mustafi starts at right-back for Arsenal.
Three centre halves and wing backs for Tottenham, with Christian Eriksen central behind Heung-Min Son and Harry Kane starting as a clear front two.
2 minutes
Arsenal press high but clever passing down the right from Kieran Trippier and Moussa Sissoko breaches the press.
But the move breaks down and Alex Iwobi picks up the ball on the left touchline.
Moving in, the Nigerian's pass is deflected up into the air, lopping over the Spurs defence and into the path of Alexnadre Lacazette, who should do better with his left-footed shot across Hugo Lloris, which is rather scuffed and dribbles wide.
