GOAL!! LACAZETTE EQUALISES AGAIN!! Martinelli beats his man down the left and crosses to the back post. It's deflected but falls kindly for Lacazette, who steers home! It's 2-2!
90'
There will be SEVEN minutes of added time. Can Arsenal grab a late equaliser?
89'
M. Guendouzi gets yellow.
Guendouzi is booked in the meantime for his complaints. Another unnecessary booking.
McCarthy comes to punch a corner clear and ends up catching Bednarek in the head. The defender stays down and needs treatment.
86'
S. Boufal enters the game and replaces S. Armstrong.
Armstrong, who had been down with an injury, now comes off for Boufal in the closing stages.
83'
J. Willock enters the game and replaces L. Torreira.
Gabriel Martinelli enters the game and replaces Héctor Bellerín.
Emery uses his final two substitutions at once as he tries to improve things. Torreira is replaced by Willock in the first alteration.
Right-back Bellerín also makes way for Martinelli, with Sokratis, David Luiz and Tierney forced into a makeshift back three.
81'
R. Bertrand gets yellow.
Bertrand is booked for time-wasting over a throw-in. That's the seventh yellow card of the afternoon.
79'
Bednarek has stayed down after taking Tierney's cross full in the face and requires treatment.
78'
Lacazette leads the charge as Arsenal counter and it's worked to Tierney via Aubameyang, but the left-back's cross is blocked by Bednarek.
76'
M. Djenepo enters the game and replaces M. Obafemi.
Obafemi is the next player to be replaced, with Djenepo coming on for him.
Minute
Description
73'
S. Long enters the game and replaces D. Ings.
Ings comes off for Long up front as Hasenhuttl adds fresh legs to press with.
71'
Penalty saved by B. Leno!
J. Ward-Prowse has scored a goal for Southampton!
Penalty Save Bernd Leno
GOAL!! Ward-Prowse makes it 2-1 to Southampton! His inital spot-kick is saved but Leno can only parry back across goal and the midfielder can smash into an empty net!
Ward-Prowse's spot-kick isn't right in the corner and Leno guesses the right way and keeps it out, but can't stop the midfielder from netting the rebound.
69'
K. Tierney gets yellow.
Tierney is aghast as he's booked on top of conceding the penalty.
68'
Guendouzi spots the run of Bellerin and picks him out over the top with a fine ball, but the right-back's low cross is blocked away.
65'
N. Pépé gets yellow.
Pepe goes in very clumsily on Bertrand and picks up a yellow card for his troubles.
63'
Hojbjerg - who's never afraid to shoot - has a particularly ambitious effort from outside the box that spins some distance wide of the target.
61'
Bertrand is back on the pitch and is moving freely again. He looks to have shaken off his knock.
60'
Bertrand is down and requires some treatment after a foul by Pepe. He limps to the sidelines and temporarily reduces his side to 10 men.
58'
The game is getting very stretched now as Arsenal start to commit numbers forward in attack. They've played much better in the second half.
55'
A corner is headed as far as Redmond outside the box and he tries to take it on the volley, but sends it miles over the bar.
46'
N. Pépé enters the game and replaces C. Chambers.
Emery makes a half-time change, bringing Pepe on for Chambers and changing to a 4-2-3-1.
We're back under way for the second half!
45' +3
HALF-TIME: ARSENAL 1-1 SOUTHAMPTON
45' +2
A. Lacazette gets yellow.
Lacazette gives the ball away sloppily when trying to link up with Guendouzi in midfield and sprints back to make amends, but only succeeds in earning himself a yellow card as he slides to bring Armstrong down.
44'
Sokratis is struggling when asked to play out from the back, particularly in the left-sided centre-back berth he has been deployed in. He's very reluctant to use his weaker foot and is hardly the most gifted footballer with the ball at his feet anyway. Southampton are pressing him into tight spaces time and again, looking to force mistakes.
41'
Lacazette produces an excellent turn on the edge of the box and plays Ozil into the box down the left. The German can quite poke it through for a team-mate, however, and soon after Ward-Prowse tries to score from inside his own half, but sends it wide.
39'
Southampton work another shooting opportunity for Ings just outside the area, but he drags his left-footed effort wide of the target.
37'
Torreira is bundled over carelessly by Obafemi in a dangerous position. David Luiz looks like he is going to take it but runs over the ball to allow Ozil to deliver, but it's cleared away.
35'
Tierney stops and then bursts past Cedric well before curling a cross into the area, but it's headed well clear.
33'
Redmond advances down the left and uses the overlap of Bertrand to good effect. The left-back fires a low cross in towards Obafemi, but the striker can't get on the end of it and Guendouzi hacks away.
31'
D. Ings gets yellow.
Ings is the latest player to go into the book, clattering into Guendouzi off the ball. There's plenty of fire in this one.
30'
Ings takes a cross it and lays it off to Hojbjerg on the edge of the box, but the midfielder drags his shot well wide of the target.
28'
S. Papastathopoulos gets yellow.
Sokratis also goes into the book for dissent after David Luiz had fouled Ings. That's a needless card to pick up.
25'
Southampton appear to have set up in a 4-4-2 rather than the 4-3-3 that was expected, with Armstrong on the right and Redmond on the left of a midfield four.
23'
L. Torreira gets yellow.
Torreira slides in to challenge Redmond and catches the winger, giving away a free-kick. The referee has his card out and there are protests from Arsenal players, but the Uruguayan is booked anyway.
18'
A. Lacazette has scored a goal for Arsenal!
GOAL! LACAZETTE EQUALISES! Aubameyang and Ozil link up cleverly before the latter plays a lovely ball in behind for Tierney to chase. The left-back gets to it well and crosses for Aubameyang, whose initial shot is blocked, but Lacazette is there to pick up the pieces and fires home on the swivel! It's 1-1!
16'
Redmond plays the ball down the line for the underlapping Bertrand, whose low cross is only half-cleared, and it's worked to Ward-Prowse on the edge of the area, but his shot from distance is tame and easily held by Leno.
12'
Lacazette is left isolated up front and can't beat the three around him, allowing Southampton to break with just one pass in behind. Obafemi fires against David Luiz and Southamption earn a string of corners, but can't captialise on any.
10'
Tierney charges down the left and fizzes a low cross in towards Aubameyang at the near post, but it's defended well and hacked clear.
8'
D. Ings has scored a goal for Southampton! Assist by R. Bertrand.
GOAL! SOUTHAMPTON TAKE THE LEAD! Bertrand takes a free-kick quickly and catches the whole Arsenal defence out, allowing Ings to race into the box down the left and fire in off the near post! It's 1-0 to Southampton!
It was a neat finish from Ings, but credit must go to Bertrand for his quick thinking to take the free-kick so sharply.
7'
Another neat touch from Lacazette nearly sees Bellerin played in on the right, but the Southampton defence scramble back to smother the chance.
6'
Lacazette shows good strength to hold the ball up on the right before going on an excellent run, but his cross is a little too heavy for Ozil on the other side of the box.
4'
OVER! Obafemi is played in behind over the top and gets the wrong side of Sokratis, but he can only spoon his attempted lob high and wide under pressure.
3'
Aubameyang tries to play the ball in behind for Lacazette after a neat turn in midfield from Torreira, but the final ball is a little too heavy for the Frenchman to latch onto.
1'
We're under way at the Emirates Stadium!
Hello and welcome to our LIVE coverage of the Premier League fixture between Arsenal and Southampton at the Emirates Stadium in London.
Under-pressure Arsenal boss Unai Emery will be hoping for a win against struggling Southampton to ease fans' ire towards him as the Gunners return to action following the international break.
Arsenal substitutes: Shkodran Mustafi, Nicolas Pepe, Ainsley Maitland-Niles, Gabriel Martinelli, Reiss Nelson, Emiliano Martínez, Joe Willock
Arsenal XI (3-4-1-2): Bernd Leno; Calum Chambers, David Luiz, Sokratis Papastathopoulos; Hector Bellerin, Lucas Torreira, Matteo Guendouzi, Kieran Tierney; Mesut Ozil; Alexandre Lacazette, Pierre-Emerick Aubameyang
Southampton XI (4-4-2): Alex McCarthy; Cedric Soares, Jan Bednarek, Jack Stephens, Ryan Bertrand; Stuart Armstrong, James Ward-Prowse, Pierre-Emile Hojbjerg, Nathan Redmond; Michael Obafemi, Danny Ings
Once again, the Gunners have been out-shot at home against opposition they would expect to dominate against, with Southampton recording 10 shots to Arsenal's three. Emery needs to get his side playing more proactively if they are to win games the way they are expected to.
