Match ends, Arsenal 2, Southampton 2.
Arsenal's winless run continued as they drew against Southampton to increase the pressure on manager Unai Emery.
The result leaves the Gunners in seventh, nine points worse off than at the corresponding stage last term, while the Saints remain 19th.
Emery's side, who were second best throughout, were booed off at the final whistle after delivering a disjointed performance which suggests they may struggle to compete for a place in the top four this season.
Danny Ings' early goal had put the visitors in front, with the forward catching the home defence asleep to race onto Ryan Bertrand's free-kick and score with a right-foot shot from close range.
That set the tone for what was to follow, with the visitors wasting several good chances to extend their lead before Alexandre Lacazette turned in a close-range equaliser.
The goal did little to kick-start Arsenal though, who fell behind for a second time when James Ward-Prowse scored on the rebound after seeing his second-half penalty saved by home goalkeeper Bernd Leno.
Not even Lacazette's second goal of the day, which came late in stoppage time, could raise spirits at the Emirates, with the forward appearing embarrassed to celebrate.
Pressure mounts on Emery
Prior to Saturday's games respective managers Unai Emery and Ralph Hassenhuttl shared the unenviable tag of being the bookmakers' joint favourites to be the next Premier League manager dismissed.
However, while Southampton's dreadful record in north London suggested they could be ideal opponents for Emery to alleviate some of the pressure on him, things did not go to plan for the Arsenal boss or his team.
And until Lacazette's late goal, his 24th at home of his 31 Premier League goals, his side had appeared likely to slip to a first home defeat against the Saints since 1987.
That was largely due to familiar failings once again resurfacing, with Southampton's pressing game and ability to bypass the Arsenal midfield clearly evident.
They were also not helped by Emery's deployment of a three-man defence of Sokratis Papastathopoulos, David Luiz and Calum Chambers.
The trio were repeatedly pulled apart by the pace of Ings and Southampton's 19-year-old Republic of Ireland forward, Michael Obafemi.
Obafemi's early dart away from Sokratis served as a warning, while Chambers' withdrawal at the interval appeared to be an admission that Emery had got his tactics wrong.
While the introduction of club record signing Nicolas Pepe did at least spark their attacking play, they always remained vulnerable in defence and were fortunate to escape with a point.
Nasty Saints return
Ralph Hasenhuttl had called on his team to become "nasty" again in the prelude to this match and his team appeared to have heeded those words with a performance brimming with energy.
The Austrian felt his team had been too passive in their opening 12 games of the season, so Stuart Armstrong's first-minute attempt on goal - coming after they had pressed Kieran Tierney into a mistake - would have been a welcome sight.
And they maintained that intensity throughout, stifling Arsenal's attempts to play out from defence, which in part, contributed to their 21 shots on goal compared to the Gunners' 12.
Ings and Obafemi were the triggers for much of that work, though Pierre-Emile Hojbjerg, Ward-Prowse, Nathan Redmond and Armstrong also featured prominently.
For large parts of the game there was also a resoluteness about their defending which had been absent so far this season.
They may still have the worst defensive record in the Premier League, but this represented a marked improvement, with Jan Bednarek playing a central role in that with seven clearances, more than any other player.
The only negative for Hasenhuttl - who looked distraught to have not claimed all three points - was his side's failure to convert any of half a dozen excellent chances to put the game beyond the hosts.
Substitute Moussa Djenepo was particularly at fault, twice failing to score from close range in the closing stages.
Man of the Match - Pierre-Emile Hojbjerg (Southampton)
'My job is to find the solution' - what they said
Arsenal manager Unai Emery: "We will take one good result to give us the confidence and chance to improve. Today we lost that opportunity.
"I can understand how the supporters feel about the team and about me. I can only say to them I'm going to work hard for a good performance and to show we can be better.
"Today the attitude was good. They [the players] wanted it, they wanted to win. We imposed ourselves for 20 minutes in the second half but overall we didn't. We are very frustrated in the dressing room, the players and I.
"I understand them [the fans] 100% because they didn't watch their team play like they want. But my job is to find the solution.
Southampton boss Ralph Hasenhuttl, speaking to BBC Match of the Day: "We were critical and tried to go back to basics. The key today was we were more on the front foot. We have to big up the positive things.
"The only way to get something from the Premier League is to be as energetic as we were today."

Remember all the idiot fans who wanted Wenger out - and they were told be careful what you wish for. I'm waiting for their apologies - It wasn't this bad!
It's easy to claim your backdated prophecies but Wenger had lost the ability to motivate the team. The fact that Emery is even worse is no reason for us to want Wenger back or to regret him leaving.
Imagine the scenes
Feel sorry for the fans, with the most expensive season ticket and other expenses to watch this rubbish every week.
How much more can the fans support?
And for what?
It's all too cosy and nice at Arsenal. Don't pick on us, don't tell us how bad we are: we need you to love us.
Arsenal in terminal decline with the Krankies at the helm.
How did we get them bad?
How can Unai Emery carry on after this display? To scrape a point against a team so bad that they conceded 9 goals at home only 3 weeks ago is tough to watch.
Emery was brought in to bring this team forward and he is dragging us deeper and deeper into the dirt. At least the spuds have the guts to sack their manager.
Now the Arsenal board must do their job.
What a mess! You've got Aubameyang befriending an aftv muppet who abused Xhaka (I don't want Xhaka at Arsenal btw). Some players still want Xhaka as captain.
Emery demanded a winger. He gets a £72m one and then plays without wingers. Ostracizes Ozil then brings him back.
Emery OUT, Pochettino IN.
Sack Emery now as we will be 8th by tomorrow if Man U/Sheffield Utd win their match. No disrespect but we are below Wolves and Burnley and for a top4 hopeful who has spent over £130m that's poor.
Promote Freddie as caretaker manager till season ends.
