It's a win for Arsenal, then, and they're up to third for the time being at least. Wigan remain in the bottom three.
Wigan look to fashion one last chance but they're thwarted and as Arsenal move clear the final whistle blows.
Beausejour whips a cross in from the left which Koscielny half-clears. It breaks back to McArthur but his side-footted effort drifts wide, with Kone just unable to land a foot on it.
Laurent Koscielny replaces Cazorla as Arsenal look to get the three points locked down.
Another Gomez shot strikes Gibbs and again the Wigan fans are up claiming for handball. Nothing doing again.
We're into four minutes of added time with Wigan still pressing.
Wigan appeal for handball as Gomez's shot strikes Gibbs. Nothing doing. Ball breaks towards Kone but Mertesacker hacks clear.
That's Maloney's last act, with Jordi Gomez replacing him.
Figueroa whips a cross in but McArthur can't get enough on the header and it dribbles harmlessly wide.
Maloney penalised again after fouling Coquelin.
Maloney booked for a tackle on Coquelin, who looked to make the most of the contact there it has to be said.
Frustration for Wigan as McManaman's ball out to Beausejour down the left is behind the full-back and slides out.
The corner from the left goes as far as McManaman beyond the far post and though he thinks he's won a corner off Sagna, the referee is right to award the goal-kick to Arsenal.
Corner to Wigan as Ramsey nicks the ball off the toes of Beausejour. Late pressure here - can they find a leveller or are they leaving themselves open to the counter-attack?
Gibbs heads the corner as far as Figueroa, but once again another of his ambitious long-range efforts is off target.
Stam gets free after springing the offside trap. He opts to cross rather than shoot but Mertesacker has tracked Kone's run superbly and slides it behind for a corner.
Figueroa does well to get across and halt Sagna's progress down the right, even earning a free-kick for his troubles.
Second change for Arsenal as Francis Coquelin replaces Podolski.
McArthur looks to spring Kone over the top but the Arsenal offside trap works well and the flag is rightly up.
Stam's final ball lets him down once again as his cross from the right sails out for a throw-in on the far side.
Wigan bring Callum McManaman on for Di Santo. The big Argentine is certainly a willing worker but hasn't really threatened the Arsenal goal today.
Walcott drills in the free-kick but it's never dipping enough to force Al Habsi into the save.
Aaron Ramsey replaces Oxlade-Chamberlain.
Wilshere looks to ride a couple of challenges but Figueroa trips him around eight outside the Wigan box. Decent chance this.
Oxlade-Chamberlain whips another decent ball in after getting past Beausejour but Stam heads clear, albeit somewhat unconvincingly.
First change of the game imminent...
Wigan go close through Jones. Beausejour crosses well for McArthur beyond the back post. He slides it back for Jones, who powers in a shot from 20 yards. Szczesny is rooted to the spot as the ball flies just wide of his left-hand post. Better from Wigan.
Kone fashions himself a shooting opportunity almost out of nothing but Szczesny does well to save.
Decent ball in from Beausejour which Mertesacker rather shanks behind for a corner. That breaks out to Figueroa, who takes a touch then fires in a shot from distance. It deflects off Arteta but Szczesny saves well.
The corner comes to nothing. Sky's man on the touchline has filled us in on 'Di Santogate'. Apparently the big striker was wearing an earring, which was only spotted by the referee when he spoke to him. As he was off for that reason he had to wait for a stoppage in order to return.
On with the game. Maloney whips a cross in from the left which Mertesacker turns behind for a corner.
Di Santo trots back on and frankly I'm none the wiser as to what happened there. That was truly bizarre. There was no blood...it was almost as though he was sin-binned for a minute for something!
Oxlade-Chamberlain gets down the right and crosses but Walcott can't get the shot away. Di Santo STILL not allowed back on the field. What is going on here?
Not sure what's happened here as Di Santo comes to the touchline to talk to fourth official Mark Halsey and isn't allowed back on the field. Everyone involved on the touchline - Di Santo, Halsey and Martinez seem genuinely baffled as to what's going on here. Wigan No 2 Graeme Jones, too, seems confused as he pitches into the conversation.
Wigan are now 16/1 with Sky Bet to turn this around, and 4/1 to carve out a draw. Arsenal have their tails up, though, with Walcott 7/1 to score next.
Niall Quinn on co-commentary for Sky Sports 3 reckons the contact from Beausejour on Walcott "warranted a penalty".
Wigan look for an immediate response but Beausejour produces an off-target shot or inaccurate cross as he gets space in the Arsenal area.
Would like to see that penalty award again - Walcott was in front of Beausejour and there did look to be some contact between Walcott's foot and Beausejour's leg but not sure how much.
Arteta sends Al Habsi the wrong way from the spot and Arsenal lead at the DW.
Walcott and Cazorla play a one-two on the right-hand side of the Arsenal box. Walcott goes down after a tangle with Beausejour and the penalty is given.
Gibbs' backpass momentarily looks to be too short but turns out to be perfectly weighted.
Figueroa again gets himself in the way as Arsenal look to break through the Wigan backline. He's had a good game.
Arsenal just turning the screw now. Another Oxlade-Chamberlain cross from the right is cleared by Figueroa, who does well not to concede the corner. Throw deep in Wigan territory though.
A Beausejour cross evades Vermaelen but not Gibbs. As the ball drops on the edge of the Arsenal box, Maloney handles and is rightfully penalised. Perhaps a little lucky to escape a booking there as that was pretty blatant.
Lovely footwork from Oxlade-Chamberlain to get away from Beausejour but the ball in from the right is too heavy. Both sides guilty of poor crossing thus far.
Stam manages to backheel the ball against his standing foot then fouls Cazorla as he looks to punish the full-back. Not his finest 15 seconds that.
Podolski's free-kick strikes the wall but still squirms through to Oxlade-Chamberlain. His ball in is rushed, though, and Wigan are able to clear.
Oxlade-Chamberlain powers forward and looks to get a shot away but as he pulls his leg back it clips McArthur's calf and he produces a complete air shot. The referee awards the free-kick, though, ruling McArthur has fouled him.
Ambitious - to say the least - effort from Figueroa from distance is always sailing well off target. High and wide.
McCarthy drives on from midfield and into the Arsenal box down the right but he's denied and the Gunners spring on the counter. Oxlade-Chamberlain gets down the right and slides it back fo Walcott, but his shot is well saved by Al Habsi. Was a little behind Walcott that so the shot wasn't powerful enough and too close to the goalkeeper but it still needed saving.
A great run from Maloney takes him into the Arsenal box down the inside-left channel but the attentions of Mertesacker are enough to put him off and he can only turn his cross behind.
Oxlade-Chamberlain gets down the right and slides the ball back for Walcott, but Boyce nips in to toe-poke it away.
McArthur nicks the ball off Walcott's toes centrally and slides it back to Al Habsi, who clears downfield.
Back under way at the DW.
Following a drab opening period, Sky Bet have boosted the price on the hosts sneaking a narrow 1-0 win to 8/1, while Arouna Kone is 11/1 to open the scoring. Meanwhile, Theo Walcott to score next and Arsenal to win 2-0 is now 22/1.
HT: Wigan 0 Arsenal 0.
That's half-time and it remains goalless. Wigan are giving Arsenal little time to play their normal passing game but while they have had plenty of crossing opportunities themselves, they're yet to really extend the Arsenal defence.
The free-kick comes to nothing but Arsenal come again as the clock ticks down only for Oxlade-Chamberlain to concede a goal-kick as he tries to hurdle Beausejour's challenge.
Maloney trips Wilshere as we enter two minutes of added time. Free-kick to Arsenal and that battle is certainly one to watch closely after the break.
Beausejour has another decent crossing opportunity but hits it too close to Szczesny with Kone advancing.
Great defending from Figueroa as he tracks back superbly with Oxlade-Chamberlain and actually wins the goal-kick in the end as the ball slides off the toes of the Arsenal man and behind.
Arsene Wenger looks bemused as the drop-ball restart is given unchallenged to Wigan - he felt Arsenal should have had the ball after the stoppage in play to ensure Wilshere was OK.
Free-kick comes to nothing and within 60 seconds it's Wilshere on the receiving end as McCarthy catches him on the side of the head with his hand as they do aerial battle.
Wilshere is the first player into the book for a robust challenge involving Maloney. The Arsenal man looks bemused - think he's suggesting he got the ball and was actually caught by Maloney but on first viewing I can see why the referee cautioned him.
Arsenal convert the throw into a corner, which is clipped in long. Arteta heads back across goal but McCarthy unceremoniously pumps it clear downfield.
Maynor Figueroa concedes a throw deep in Wigan territory. Rather unfortunate ultimately but the result of him attempting to play his way out of defence.
Maloney works the ball out to Beausejour in space down the left, but the flag is up for offside. Tight one that.
Stam looks to make headway down the right once again but Gibbs tracks well and the Dutchman has to come back inside and turn the ball back towards his own goal.
Wilshere looks to be moving much more freely now by the way. Apologies to those Arsenal fans I had fretting earlier!
Maloney's attempted cutback to David Jones is blocked but Beausejour picks it up out wide. It's a good crossing opportunity once again but sails behind for another goal-kick.
Stam appeals for handball as his cross rears up of Kieran Gibbs but the officials aren't having any of it.
Better from Arsenal as they work the ball into Walcott just inside the area but Boyce is in quickly to block his shot and Wigan clear downfield. Cracking ball from Cazorla into Walcott's feet that.
Possession stats show it's 50% apiece thus far.
Di Santo slides the ball across the Arsenal area after cutting back inside onto his right but it drifts through untouched and out for a goal-kick.
Stam again gets space to cross from the right but he overhits this one badly and it sails out for a goal-kick. Poor that.
Stam again gallops down the right but can't quite get an effective cross into the box and Arsenal clear. Not sure Wilshere is moving too freely at the moment but will keep an eye on that one.
Beausejour's tracking of Oxlade-Chamberlain is symptomatic of the Wigan performance so far - they're barely giving Arsenal an inch.
Arteta's ball in towards the back post is aimed for Vermaelen but Boyce does well to nick in first and head it out for a throw-in.
Beausejour sends Oxlade-Chamberlain spinning to the deck. Free-kick Arsenal out on the right around 35 yards from the byline.
Encouraging for Wigan that, no question, as Kone left Mertesacker treading water but you've got to take chances like that.
Kone springs the Arsenal offside trap onto a lovely ball from Di Santo and leaves Mertesacker trailing in his wake. He advances one-on-one on Szczesny but then shanks his left-footed shot wide. Should have got that on target at the very least. Great chance.
McArthur does well to track Wilshere's run and slide the ball out for a throw-in to Arsenal deep in Wigan territory.
As the free-kick is clipped forward, Sagna is penalised for baulking Maloney as they challenge for the ball.
Beausejour slides in to try and stop Sagna getting foward but the ball strikes his hand and Arsenal get the free-kick.
Arsenal try to work a chance for Oxlade-Chamberlain down the right but Beausejour tracks back well to shepherd it out.
After good work from Di Santo centrally, Beausejour whips a cross in but it drifts behind for a goal-kick. Maloney returns to the action with what looks a decent dollop of Vaseline on his head.
Jean Beausejour tries to get at Sagna but the Arsenal man tracks well and slides it back to Per Mertesacker to clear.
Jack Wilshere bursts towards the edge of the Wigan are but he's tracked all the way and overhits his pass to Walcott. Maloney has taken a bump on the head and is just having that one patched up so the Latics are momentarily down to 10 men.
Another snapshot from Podolski, though this one is always sailing over the crossbar without troubling Al Habsi.
Wigan getting through plenty of work when they don't have the ball. Worry is always whether they'll be able to sustain such a high level of intensity but it's working so far.
Di Santo and Shaun Maloney try to link up down the inside-right channel but the latter's ball is a shade too heavy and Szczesny is able to gather. Stam was the ball there, though - he's making some great runs early in the game.
Cazorla slides in a cross from the right but Emerson Boyce clears centrally under pressure from Theo Walcott.
A Lukas Podolski snapshot tests Al Habsi. The ball is eventually worked back to the Germany international but his second shot on the volley is blocked and cleared.
Kone skips past Vermaelen centrally and powers forward. But with Stam up in support and in space on the right, the striker inexplicably opts to shoot and it's an awful effort.
Good defensive pressing from Wigan forces Arsenal to go right the way back to Szczesny as the corner comes to nothing.
Lovely flick from Cazorla in midfield sets Arsenal on the attack. Arteta bursts forward and slides it out to Alex Oxlade-Chamberlain down the right. He fires in a shot which Ali Al Habsi has to dive sharply to his right to turn behind for a corner.
Another cross from the Wigan right but this time Stam's delivery sails behind and Wojciech Szczesny can clear via a goal-kick.
James McArthur dinks a lovely ball over the Arsenal backline for Kone, but he's gone a split-second to early and the offside flag is rightly up. Bright start this from Wigan, though.
Guess what? Di Santo whips another cross in from the right. It's too high this time, though, and Sagna clears down the Arsenal right.
It's like Groundhog Minute at the moment here. A third successive Wigan attack comes down the right and Di Santo whips a cross in but again Vermaelen clears the danger.
Di Santo now gets down the right and whips the ball into the middle but this time Thomas Vermaelen hacks clear with Arouna Kone waiting to pounce on any mistake.
Ronnie Stam whips the ball in from the right into the Arsenal box but Mikel Arteta sweeps it away at the expense of a throw-in.
Martinez already doing plenty of gesticulating and urging his players on from the touchline.
Corner cleared at the front post and Franco Di Santo then draws a foul from Santi Cazorla allowing Wigan to ease the early pressure on their backline.
Early possession from Wigan but Arsenal then break down the right through Bacary Sagna. He gets to the byline and his cross is turned behind for a corner. Though Wigan thought he'd carried it over himself.
Wigan get us under way. It's wet, but we've got a game on.
The teams are out on the pitch.
Roberto Martinez says Wigan face a "big challenge" against an "outstanding football team". He wants his side to get on the ball and pose Arsenal problems and expects an open game with many chances.
Robert writes: "I think Wigan could come away with all three points today. Not a Wigan supporter, don't know why, I can just sense it. Wigan to win 2-1."
Martyn writes: "Afternoon all. You asked if Wigan can win this. Well if Arsenal play anything like they did at Norwich, then yes, without a doubt!"
By way of a summary of those teamlists from earlier, Arsenal boss Arsene Wenger has named the same side that beat Reading on Monday. Wigan, meanwhile, are in the midst of an injury crisis and of eight likely absentees only James McCarthy makes the starting line-up after recovering from an ankle problem, although captain Gary Caldwell is on the bench.
If you're staring out of the window at rain, head for Guernsey. Emma Thomson says it's sunny there, adding: "Arsenal 4-0, Cazorla at the treble." Have also had a shout for a Theo Walcott hat-trick. Anyone see a way Wigan can win this?
Dave writes: "Can't believe it - after all the fuss Arsenal could be 3rd in the Prem in a couple of hours although briefly maybe. We should give this guy Wenger a few more weeks!"
Gabriel writes: "I can see a heavy Arsenal win. They will cause Wigan's unstable-looking back three a lot of problems with their pace and movement out wide, and the Latics have a lot of key players out. We could be seeing a cricket score."
Mustafa writes: "Despite getting Bayern Munich for the next stage of the Champions League, after Arsenal's recovery from the Bradford game there are good spirits and the team are doing well. Arsenal to win 2-0!"
Anthony writes; "I am a massive Gooner and am expecting another Santi masterclass. What would we have done so far without him?!"
Brian writes: "A Wigan fan, sat in the DW not expecting a big crowd today, fearful of the score, Santi's on fire!"
If you're planning a bet on the game, Sky Bet make Arsenal 4/6 to come away from Wigan with the win, while the unpredictable hosts can be backed at 4/1. There are also a number of price boosts on scorecasts available, with the pick of the bunch looking like Theo Walcott to score first and Arsenal to win 3-0 at 60/1. Fresh from his hat-trick against Reading last time out, Santi Cazorla is a tempting 7/1 to score first.
Arsenal: Szczesny, Sagna, Mertesacker, Vermaelen, Gibbs, Arteta, Wilshere, Oxlade-Chamberlain, Cazorla, Podolski, Walcott. Subs: Mannone, Jenkinson, Koscielny, Coquelin, Ramsey, Arshavin, Gervinho.
The teams are in. Wigan: Al Habsi, Kone, McCarthy, Jones, Di Santo, Maloney, McArthur, Boyce, Beausejour, Stam, Figueroa. Subs: Pollitt, Caldwell, Gomez, McManaman, Boselli, Fyvie, Golobart.
