Thanks for joining us and stick with ESPN FC for the report and post-match reaction.
For Arsenal, it's another three points and keeps the momentum going after the victory over Reading. Walcott failed to shine throughout much of the match as the central striker, but he earned the penalty that decided the game.
Arsenal secure a hard-fought victory. Wigan will rue missed chances - particularly Kone's one-on-one effort in the first half - but the hosts can be proud of their efforts given the injury problems that have beset them.
Koscielny does well to pressurise Gomez on the edge of the area and Arsenal break away.
Wigan try to work space around the edge of the box. Beausejour, at the second attempt, finds McArthur in the centre but the midfielder can't find the target with his shot.

Koscielny is on for Cazorla.
Gomez shoots against Vermaelen and there are more, slightly less vociferous, shouts for handball.

Wigan are on top, but they're struggling to make any real headway.

Stam centres the ball but Mertesacker makes a vital interception with Kone ready to turn home.
Sagna looks to burst free, but ends up fouling Figueroa.

Kone is belatedly but correctly given offside.
Wilshere runs into traffic and loses possession.
Stam once more sends over a cross from the right that fails to find its target.
McManaman is on for Di Santo.
Walcott curls the free-kick over the bar. Not a bad effort but Al Habsi was never troubled.

It's taken short and Jones ends up flicking it out of play.
Maloney sends in a cross that comes off Mertesacker for a corner.

Wigan are still down to ten men - and the crowd are furious. Walcott, in the meantime, fails to make a chance count.
Di Santo is off the field for reasons no one seems to be able to understand.
Di Santo is penalised for a foul on Gibbs, and the ref has a word with him for his constant complaints. The home fans are not happy with the officiating today.
Podolski looks to feed the ball through for Gibbs, but it's overhit and the left-back can't latch onto it.
Wigan look to respond instantly, and McCarthy races at the defence before feeding Beausejour, who hits the ball across goal for a goal kick. Disappointing once more.
GOAL FOR ARSENAL! The Spaniard makes no mistake, sending the goalkeeper the wrong way.

Alex Oxlade-Chamberlain and Jean Beausejour do battle.
The Wigan defence, despite the injury woes and McCarthy deployed out of position, can be very pleased with how they've handled this first half.
A fairly even first half, with both sides struggling to force any real chances. Arsenal, you suspect, would like to have Giroud available to give them another option.
Walcott looks to collect a pass over the top but has to settle for a throw-in. He's not had too much to work with in this first half.

Stam once more gets himself into an excellent position out on the right, but once more the cross is poor.
McArthur bends a pass out to Stam on the right, but the cross in the end fails to cause any problems.

...but then the Ox wins a free-kick from Beausejour out on the right.

Walcott slides in a dangerous-looking cross but Boyce is able to get it clear.
At the other end, Podolski unleashes a shot that Al Habsi is able to parry and then, a few seconds later, the German sees a shot blocked.

Arsenal once more fail to make anything of the corner.
CHANCE! Arteta finds Oxlade-Chamberlain in the box and the England winger's shot is pushed behind for a corner.
