Arsenal's lead at the top of the Premier League stands at just four points after they were held to a 1-1 draw by high-flying Brentford on Thursday.
Mikel Arteta's side were looking to respond to Manchester City's 3-0 win over Fulham on Wednesday, but were far from their best at the Gtech Community Stadium.
Noni Madueke gave Arsenal the lead from their first attempt on target just after the hour, only for Keane Lewis-Potter to score a header of his own 10 minutes later.
Igor Thiago and Gabriel Martinelli both went close at either end late on in a gripping end to the contest, but the points were ultimately shared.
Without key defender William Saliba due to illness, Arsenal required David Raya's fine save from Thiago's header to keep the scoreline level at the interval.
Arsenal improved early in the second half when Martin Odegaard replaced Eberechi Eze, with Madueke heading in from Piero Hincapie's delivery to give the visitors the lead.
But Lewis-Potter got on the end of a Michael Kayode long throw into the box, which was flicked on by Sepp van den Berg, to earn Brentford a point they will feel they deserved.

Data Debrief: Arsenal let down by attackers
Arsenal registered an expected goals (xG) of just 0.6 in west London, their third-lowest tally in a Premier League game this season, behind both games against Liverpool.
Indeed, only against Wolves in December (68th minute) have Arsenal had to wait longer for their first shot on target in a match this campaign than against Brentford (61 mins).
Viktor Gyokeres has picked up of late but failed to register a shot, while Eze has failed to score or assist in 10 league games since his North London Derby hat-trick.
Given Arsenal have been so strong themselves from set-pieces this season, it was ironic that Brentford's equaliser came from a long-throw into the box.
It is the fourth long-throw Brentford have scored from in the Premier League this term – only Burnley have as many – as the Bees moved back to within two points of sixth-place Liverpool.
