WALCOTT REALLY SHOULD HAVE HIS HAT-TRICK! Oxlade-Chamberlain's power takes him past his man and he's got the option of a shot or a pass. He chooses the latter, but Walcott smacks his finish onto the crossbar!
90' +3
Deep into stoppage time now and Arsenal have passed up a great chance to wrap this up as Bellerin scampers to the near post past his marker, but can't prod his finish past Fabianski!
90' +2
CECH SAVES AGAIN! After a probing piece of play from Swansea, Rangel swings in a cross to the back post where Fernandez rises to get his head on the ball, but there's not enough direction to seriously trouble the keeper!
90'
Every single player bar Fabianski is camped in the Arsenal half now as Swansea desperately seek an equaliser. This is a great opportunity for them to get a point, when a defeat seemed inevitable.
88'
DOWN THE THROAT OF CECH AGAIN! Swansea manufacture a great chance to tie things up as Naughton's in-swinging cross from the right-hand side is past Mustafi and headed on goal by Fer, but he can't beat the keeper.
86'
No one is leaving this game early as the action surges from end to end. Arsenal will feel that attack is the best form of defence to keep the ball away from their own area, but too much of that and Swansea could fashion one last great chance.
84'
OFF THE INSIDE OF THE POST AND OUT! Fer is careless again on the ball and Arsenal break. Oxlade Chamberlain plays a ball to Walcott, who cuts inside his man and curls a low finish that should have wrapped it up.
83'
Àngel Rangel enters the game and replaces M. Barrow.
K. Gibbs enters the game and replaces M. Özil.
Not quite as it turns out, with the limping Barrow replaced by Angel Rangel.
Keiran Gibbs has been thrown on to help out against Barrow, with Ozil making way.
82'
A. Oxlade-Chamberlain enters the game and replaces A. Sánchez.
First of three changes here as Alexis is withdrawn for Oxlade-Chamberlain.
81'
For the third time in the second half, the offside flag denies Arsenal a good-looking attack. The Arsenal fans aren't happy with that decision, but it's the right call as the ball comes back at them.
Minute
Description
79'
OH MY WORD, WHAT A CHANCE! Naughton clips in a ball that has Monreal hopelessly out of position against Barrow, who has time and space but plants his header down the throat of Cech!
77'
Sigurdsson whips in a great delivery, but Cech punches it just before the offside flag is raised. Concerned faces from Arsene Wenger and Steve Bould on the Arsenal bench.
75'
Swansea really fancy this now, and Arsenal are rattled after they feel that a few decisions have gone against them. The visitors have a free-kick in a good position out on the left flank.
72'
What a chance for Swansea now, who have a man advantage and a decent chunk of time to hunt down a third goal! Arsenal have no one but themsevles to blame if they fail to win this.
71'
Ki Sung-Yueng enters the game and replaces J. Cork.
Cork jogs off to be replaced by Ki.
70'
G. Xhaka goes off after a red card!
XHAKA HAS BEEN SENT OFF! It's Barrow who causes them problems again, skipping past the Swiss international on the touchline, before he is flattened by a terrible challenge.
68'
F. Coquelin enters the game and replaces A. Iwobi.
Iwobi has been taken off, and on comes Coquelin.
That was poor defending from Arsenal, who have let Swansea back in the game again. What was supposed to be an easy half-hour to finish the game now sees the home side looking over their shoulder.
66'
Borja Bastón has scored a goal for Swansea City! Assist by M. Barrow.
He's been working hard all game out wide and now makes a decisive impact.
SWANSEA ARE BACK IN IT AGAIN! Barrow takes his time to slide a short cross into the area where Borja arrives between the static Koscielny and Mustafi to finish from very close range!
64'
OFFSIDE AGAINST BORJA! Arsenal commit another mistake at the back as Koscielny gifts Swansea possession in a dangerous area but Barrow passes to the substitute in an illegal position.
62'
Couple of narrow offsides that kill Arsenal's momentum. It's back to be fairly straightforward for Arsene Wenger's team now, who have rarely looked in danger in the second period.
60'
Borja Bastón enters the game and replaces L. Britton.
Cazorla finds Bellerin down the right and there's a chance for him to drive at the defence, but he fails to find a teammate. Swansea are all over the place though, as Alexis twice has the chance to score.
Britton has been withdrawn for Borja.
57'
M. Özil has scored a goal for Arsenal! Assist by A. Sánchez.
Good awareness from the Chilean to clip that one in.
BIRTHDAY BULLET! Ozil marks his 28th year on Earth with an out-of-this-world finish. He ghosted to the back post behind Fernandez and thumped in Alexis' cross on the volley!
56'
ARSENAL SOMEHOW FAIL TO SCORE! Iwobi's mesmerizing feet send him deep into the box. His cross causes problems and somehow, during the scramble, Walcott can't convert his hat-trick goal from yards out!
55'
Ozil slides a pass to Alexis and continues his run into the box, coming within inches of latching onto the Chilean's return flick, only for Fernandez to make an important interception.
54'
Far more sober start to the second half from Arsenal, who are taking some time to get back into their rhythm. Alexis hasn't been at his best up front as he's dropped deep but usually found himself swarmed.
52'
Barrow again is asking questions of the Arsenal defence as Sigurdsson tries to thread the needle with a pass to the wide man, but Koscielny intercepts before Mustafi completes the clearance.
50'
Fer looks for Barrow with a long ball, and he collides with Monreal, sending the defender flying. Arsenal want a free-kick, but the referee correctly decides to let that one ride as it was accidental.
48'
N. Taylor gets yellow.
Oof. Alexis slides a pass through to Ozil, who has Taylor for company. The defender hasn't done a whole lot wrong in this game, but he comes in late on the German. Yellow card.
46'
We're back.
45' +1
With Naughton out of position, Arsenal attack via Alexis. The Chilean international makes the wrong choice though, taking a shot instead of passing to the wide open Monreal on the overlap.
44'
Ozil flicks one in for Walcott, who is too quick for Amat and is caught by the centre-back, but the referee refuses to blow for a free-kick to the fuy of the home fans. The forward was actually caught in his eye and needs on-pitch treatment.
42'
Barrow has done very well for Swansea on the right flank, and he sticks a ball into the feet of Sigurdsson at the near post, but Mustafi is tight on the Icelandic attacker, and forces a goal-kick.
40'
That goal has given Swansea a lift - can they do something with the momentum before half-time? Arsenal certainly seem nervy as Cech nearly presents the visitors with another chance after a poor clearance.
38'
G. Sigurðsson has scored a goal for Swansea City!
SWANSEA ARE BACK IN IT! Xhaka gifted the visitors that chance as he stumbled on the ball at the top of the box, but Sigurdsson, who pounced on it, still had a lot to do, converting a fine finish to shock the Emirates!
37'
Moment of panic for Arsenal as Mustafi's challenge on Sigurdsson falls to Barrow, who pings it forward for the Icelandic international, but Cech is off his line quickly to clean up the mess.
35'
Arsenal are threatening to run away with this here as a delightful one-two with Cazorla sees Ozil scamper down the byline, but he takes one touch too many and can't tee up a colleague for the finish.
33'
T. Walcott has scored a goal for Arsenal!
TWO FOR THEO! Atrocious defending from Swansea. A corner drops to the centre of the box where Fernandez misses his header. That was bad, and even worse was the fact that Walcott had the time to control, spin and finish about four yards from goal.
32'
FABULOUS FOOTBALL! Walcott stabs a lovely early ball for Ozil, who then lets Bellerin run onto it on the overlap. The Spaniard is about to finish, but Taylor gets enough on it to take it wide!
30'
Great early ball from Xhaka to split the centre-backs and find Alexis through. His first touch takes him off stride a little, so he attempts to lob Fabianski from 25 yards, sending it wide of the post.
28'
Well it has been coming for the home side. Like their goal against Burnley, it was far from the prettiest thing, but great hustle by Walcott to get on the end of that one. He's a different man this season.
26'
T. Walcott has scored a goal for Arsenal!
ARSENAL SQUEEZE IT IN! Ozil scooped a ball to the back post from a central area, and Bellerin wins the header against Routledge. Amat appeared to have it covered, but Walcott nipped in and through sheer determination, won the ball and forced it over the line!
25'
BIG interception from Taylor, who, on the slide, gets a toe on the ball before Walcott was able to break through for a one-on-one with Fabianski. Arsenal are also aggrieved that a challenge on Cazorla didn't lead to a free-kick.
23'
Cazorla finds Ozil with a lovely pass down the left after Fernandez turned it over with a slack pass out of the back. He tees up Xhaka inside the D, but the midfielder telegraphs his effort and Britton makes the block.
21'
OVER THE BAR! What a chance for the visitors. Barrow cuts the ball into Naughton, who then lays it off for Fer at the top of the box. He leans back and slides his effort narrowly above goal!
19'
Swansea appear to have settled somewhat, or perhaps it's just Arsenal taking their foot off the accelerator in the last few minutes. Barrow is giving them a few things to think about out wide.
17'
Fer commits a very careless turnover which is nearly costly for his side as they were outnumbered on the break, but Amat makes a crucial challenge to prevent Walcott from being put through.
15'
OFF THE CROSSBAR! Ozil delivers the ball into the mixer, and Mustafi gets the step on Amat, glancing a header towards goal but seeing it bounce off the top of the woodwork! Closest they've come.
13'
Fernandez gets across to make a challenge on Alexis, but with the ball heading back towards the byline, Fabianski can't prevent it from heading out for a corner, which Ozil prepares to take.
11'
Barrow gets the ball down the right and has Koscielny for company. There's no time to wait for support as he decides to make a play, but the defender shepherds it out for a corner, which is wasted.
9'
It's all neat and tidy from the Gunners at the top of the box as they try to pick the Swansea lock. You get the feeling that it won't be long before Fabianski is called into action in goal.
7'
Swansea earn a rare respite from Arsenal pressure with a free-kick on the left-hand side, but Sigurdsson's floater is dealt with by the defence. The hosts can't quite coordinate a break between Alexis and Walcott.
5'
Alexis is confronted by Britton but still hooks the ball over the top towards Monreal, but Naughton intercepts it on the slide. It comes right back at the visitors though, who are penned in.
3'
Intricate...perhaps a little too much so from the Gunners. Ozil shifts the ball to Iwobi at the top of the box, and he shimmies past his man but passes up a shot to keep possession going. Swansea crowd out his eventual effort.
1'
Off we go!
Hello and welcome to our live commentary of the Premier League match between Arsenal and Swansea at the Emirates. The Gunners are chasing their sixth straight league win - but are up against a side that have beaten them in the last two games at this ground.
Arsene Wenger's side were in good form prior to the international break, with the scrappiest of goals from Laurent Koscielny edging them past Burnley 1-0 for their fifth win on the bounce. They're two points behind Manchester City at the Premier League summit.
Bob Bradley takes charge of his first match as Swansea boss, and in the process, becomes the first ever American to manage in the Premier League. before his arrival, they picked up only four points from seven games, which got Francesco Guidolin sacked on his birthday 12 days ago.
Swansea subs: Nordfeldt, Ki, Van der Hoorn, Borja Baston, Rangel, Kingsley, Fulton.
It's the same Gunners side which beat Burnley before the international break. No Olivier Giroud or Aaron Ramsey, who are both nursing knocks. Alexis Sanchez leads the line, while Santi Cazorla and Granit Xhaka man the middle of the park.
Bradley makes three changes to the side that fell to Liverpool two weeks ago. Angel Rangel, Mike van der Hoorn and Borja Gonzalez will all have to settle for a spot on the bench. In comes Federico Fernandez, Modou Barrow and Neil Taylor.
And that will do it from the Emirates for now. An error-strewn first half it has been, with three mistakes leading to three goals in the opening 45 minutes. Theo Walcott's double seemed to make things comfortable for the hosts, but Sigurdsson pulled one back to keep things tight. A lot to play for in the second half so stay tuned.
FULL TIME! A whirlwind end to this game as Arsenal manage to tiptoe over the line to pick up their sixth straight win. At 3-1 the Gunners were cruising, but Borja's goal and Xhaka's red card made things very interesting. Defeat for Bob Bradley in his first Swansea game, which has given him a lot to chew on tonight. That's all from us, thanks for tuning in!
