Kim Kallstrom digs in a cross from the left but Scott carson reads the situation well and comes out to claim a comfortable catch.

Yaya Sanogo has a shot blocked from close range as Arsenal desperately try to find a winner before the lottery of penalties.
James Perch whips in a pinpoint cross from the right and Jack Collison meets it with a firm header in the centre, but directs it just wide of Lukasz Fabianski's left-hand post.
Alex Oxlade-Chamberlain unleashes a piledriver from the edge of the area and beats Scott Carson with a swerving effort, but unfortunately the ball crashes against the post and ricochets away to safety.
Lukasz Fabianski wanders out of his area to try and reach a long ball but realises his mistake just quickly enough and is able to get back to goal before Nick Powell tries to shoot from out wide.
There are some tired challenges going in now and Arsenal have a chance as they get a free-kick in a central area 30 yards from goal, but Santi Cazorla's delivery is headed strongly away by Gary Caldwell.
There is still nothing to separate the sides at half-time in extra-time, and we are now just 15 minutes away from a penalty shoot-out.
Mikel Arteta gives away a free-kick for hauling down Jordi Gomez in midfield but Olivier Giroud heads clear as the ball is launched forward.

Nick Powell slips in the box and is dispossessed by Per Mertesacker as Arsenal survive a brief scare.
Yaya Sanogo again shows his physical side as he latches on to a loose ball in the box and tries to hook it athletically past Scott Carson as it bounces high, but is unable to keep the shot below the bar.
Yaya Sanogo links up well with Olivier Giroud and spins quickly to let off a ferocious shot. It is from an acute angle, though, and Scott Carson raises a hand to parry it over the bar.

Kieran Gibbs loses the ball high up the pitch and Wigan break, but Jordi Gomez blasts over from the edge of the area.
Extra-time gets underway and Arsenal will hope to keep their momentum going and try to win this without the need for penalties.
The final whistle goes but the tie is not over yet, and the managers will have just a few minutes to prepare their players for extra-time.
Bacary Sagna delivers an inviting cross from the right which is just too high for Olivier Giroud and Yaya Sanogo is also unable to stretch out a leg to provide a finishing touch.
Wigan relieve the pressure and win a corner thanks to good play from Marc-Antoine Fortune, but Yaya Sanogo turns it away.
It is one-way traffic as Arsenal pour forward, but Scott Carson keeps Wigan on level terms with a fine save down to his left as Olivier Giroud fires off a low shot from 20 yards.

Scott Carson saves brilliantly from Kieran Gibbs' header as the Arsenal onslaught continues, but only succeeds in taking the pace off the ball and Stephen Crainey is needed to rush back and clear off the line.
OFF THE POST! Alex Oxlade-Chamberlain's corner is poor but he gets a second chance to send in a cross and Bacary Sagna heads against the post at the crossbar.
Olivier Giroud almost chases down a high, bouncing pass from the back and Arsenal get a corner as Scott Carson comes out to claw it behind.
Jordi Gomez becomes the first player on either side to be shown a yellow card following a cynical foul on Olivier Giroud as Arsenal threaten a counter-attack.
Nick Powell does brilliantly to hold up the ball and win a free-kick just outside the Arsenal area as he is brought down by Mikel Arteta, but Jordi Gomez's delivery is headed clear by Thomas Vermaelen.
Arsenal are trying to push Wigan back but they are still missing a creative spark and too many passes are going astray just as the pressure looks like it is starting to build.
Alex Oxlade-Chamberlain lets fly with a powerful strike from distance which fizzes through a packed area, but Scott Carson does well to get down to his left and make a solid stop.
Mikel Arteta releases Yaya Sanogo through the centre with a great pass but Stephen Crainey is back quickly to make the challenge and frustrate Arsenal again.
Olivier Giroud decides to try and play an extra pass rather than go for goal from the edge of the area, but he fails to find a team-mate and the groans ring out from Arsenal fans at Wembley.
A Jack Collison handball gives Arsenal a free-kick in midfield but they opt to play it short and keep possession rather than launch it into Wigan territory.
Arsenal's second substitution sees Olivier Giroud come on for Lukas Podolski, and there are some boos around the ground as the change is made.
The goal has stung Arsenal into action and now there is an urgency about their play as Aaron Ramsey buzzes around the area and crosses for Yaya Sanogo, who steers a first-time shot wide.
Uwe Rosler makes his first change of the afternoon to shore up his midfield, bringing on Jack Collison for Josh McEachran.
GOAL! Jordi Gomez holds his nerve admirably to fire Wigan into a 1-0 lead. Lukasz Fabianski guesses the correct way and dives to his right, but Gomez's spot-kick is far enough into the corner to find the net and Wigan are on the verge of another famous shock.
Jordi Gomez will have to wait to take Wigan's penalty as Nacho Monreal is down receiving treatment for an injury, and a stretcher has to come on to carry the full-back from the field. Kieran Gibbs comes on to replace Monreal.
PENALTY! Callum McManaman has been a livewire all afternoon and he skips away from a couple of challenges to drive into the Arsenal area. He is then too quick for Per Mertesacker, who catches McManaman with an outstretched leg and referee Michael Oliver has no hesitation in pointing to the spot.
Another promising Arsenal move fizzles out as Lukas Podolski's pass through for Nacho Monreal is too heavy and goes out for a goal-kick.
Arsenal's passing is just looking a bit slicker at the moment as they begin to apply some pressure, but Aaron Ramsey then gives away a free-kick near the corner flag for a foul on James Perch. Ramsey has barely played in 2014 and may just be starting to feel fatigued.
Lukas Podolski tries to make something happen for Arsenal with a run to the byline before cutting back a decent cross, but Ivan Ramis has been excellent so far and makes another important clearance.
Wigan surge forward and win a corner. The ball breaks for James McArthur on the edge of the area but his shot is blocked in a crowded area.
Yaya Sanogo has been a handful for Wigan's defence with his pace but he has not quite been able to create enough space for himself to make a decisive contribution, and on this occasion it is Ivan Ramis who holds him off to usher the ball back to Scott Carson.
Jean Beausejour attempts a cross from the left wing but sends it straight over the crossbar, but it may not have made much difference anyway as the penalty area was empty.
Nacho Monreal's overlapping run is picked out by Santi Cazorla but James Perch steps in with a strong challenge and Callum McManaman continues the good work to get the ball clear.
Arsenal will need to show more intensity if they are to break down Wigan's spirited resistance but the pattern of the game just now has picked up where the first half left off, which is to say they are having a lot of possession without really setting fast tempo.
Arsenal get the second half started and the tie is still up for grabs after a goalless opening 45 minutes. There have been no changes at the interval.
The half-time whistle goes and it remains goalless at Wembley. Arsenal have had the most possession and more chances, but since the early stages they have struggled to carve out clear-cut opportunities and Wigan have looked increasingly confident.
Scott Carson puts Wigan into trouble unnecessarily as he plays it short when a long ball looked to be the right option, but Arsenal cannot capitalise.
There is a moment of concern for Wigan as James Perch picks up a knock following a challenge by Lukas Podolski, but after a bit of treatment he is fine to carry on.
Yaya Sanogo shows his value to Arsenal with a quick run to latch on to Santi Cazorla's pass, but his touch takes him wide and Scott Carson is out quickly to make a sprawling save.

Lukas Podolski steps up to take a free-kick 25 yards from goal after more good play from Alex Oxlade-Chamberlain, but his curling effort flies wide of Scott Carson's left-hand post.
James McArthur charges forward on a direct run before laying the ball off to Marc-Antoine Fortune, who shoots straight at Lukasz Fabianski from a tight angle.
Wigan win a free-kick wide on the left but Jordi Gomez's delivery is flicked away to partial safety by Yaya Sanogo's header. Callum McManaman picks up the ball on the far side and drills over a cross which is too powerful for his team-mates in the centre.
Lukas Podolski has to step over to the touchline momentarily to receive treatment for a facial injury but is quickly back into the action.
Alex Oxlade-Chamberlain picks himself up from a challenge which leaves him on the floor to keep an Arsenal attack ticking over, but Wigan have so many bodies back on the edge of the box that Yaya Sanogo eventually decides to go for goal from distance and blazes high and wide.
Wigan are having a good spell just at the moment but they have yet to really get Jean Beausejour into the game, and he can be a threat with his crossing.
Callum McManaman looks to have the better of Thomas Vermaelen in his duel with the Arsenal defender and drives into the box on a strong run before pulling back a decent cross, which Per Mertesacker clears in no-nonsense fashion.
Nacho Monreal manages to steal the ball in a congested midfield and tries to set up an Arsenal break, but James Perch is alert to the danger and quickly wins back possession.
Jordi Gomez finds some space down the left wing but fails to send in a cross as his disappointing delivery flies right over the crossbar.
The Arsenal corner is flicked on for Bacary Sagna at the back post and, even though it is from a tight angle, it is a good chance for the full-back. However, Sagna is unable to fire his shot even on target on the half-volley.
Aaron Ramsey has a chance to thread a pass through for Yaya Sanogo but it is just too short and the striker gets the ball caught in his feet, allowing Ivan Ramis to get back and boot it out for a corner.
Aaron Ramsey and Alex Oxlade-Chamberlain combine neatly to play their way into the Wigan area, but Stephen Crainey is a hard man to shrug off and makes the challenge.
Callum McManaman, in particularly, is catching the eye with his hard work as he races across to tackle Nacho Monreal from Lukasz Fabianski's long throw.
Arsenal are being closed down quickly and Wigan's pressing pays dividends as Lukas Podolski sends a stray pass straight out of play.
Wigan win a free-kick in the Arsenal half and Jordi Gomez plays it short to Callum McManaman, who skilfully evades Mikel Arteta but is then unable to keep the ball from creeping over the byline.
Wigan look very organised with a strong presence in midfield and Arsenal are having to be very patient at the moment as they wait for an opening.
When Wigan do have the ball, Mikel Arteta is doing a good job at breaking up their possession, while Alex Oxlade-Chamberlain is looking particularly sharp.
Aaron Ramsey launches a long ball over the top and Alex Oxlade-Chamberlian shows his pace to outrun his defender, but Scott Carson rushes quickly off his line to spread himself wide and make a smothering save.
After a breathless start the game has just calmed down a bit now as Arsenal hold on to possession and Wigan sit a little deeper.
Arsenal settle into a nice passing rhythm in midfield as Wigan regroup in defence. Aaron Ramsey is roaming all over the pitch looking for the ball.
Arsenal are showing a lot of urgency in the early stages but, in their eagerness to win the ball in an advanced area, James Perch is fouled just outside the Wigan box to give the Championship side some respite.
Marc-Antoine Fortune threatens in the Arsenal area but Thomas Vermaelen steps in with an important, and well-timed tackle. He had to be perfect with that challenge, otherwise it would have surely been a penalty.
Arsenal spring forward and nearly open the scoring as Alex Oxlade-Chamberlain digs out a great cross for Yaya Sanogo. The young Frenchman heads powerfully downwards but it is straight at Scott Carson and he makes a smart stop, before Ivan Ramis clears away the rebound.
Wigan, playing with a three-man defence, are enjoying plenty of the ball just at the moment and look very composed, totally unfazed by the big occasion.
There is a great atmosphere at the ground as the challenges fly in, with both sides looking to gain the upper hand in the crucial battleground of central midfield.
Ivan Ramis gives away possession in a dangerous area early on and Arsenal have a chance to break, but Yaya Sanogo's touch in the penalty area just takes Alex Oxlade-Chamberlain by surprise and he is unable to keep the ball under control as it runs through for Scott Carson to gather.
Wigan get the game started and let us hope for an exciting encounter. Remember, there are no replays at this stage of the FA Cup so one of the places in the final will be decided over the next two hours or so.
The teams gather round the centre circle as everyone at Wembley falls silent to mark the 25th anniversary of the tragedy at Hillsborough, and a moment later spontaneous applause breaks out as people pay their respects.
The players emerge from the tunnel to a great reception, before the two captains join FA chairman Greg Dyke in laying wreaths in memory of the 96 victims of the Hillsborough disaster.
Glenn Howard says: "Wigan fan here. I'm immensely proud of my lads regardless of what happens today, we're still living the dream and believing! I fancy our chances today, I see Podolski's already talking about Arsenal's 'A game' and how Wigan can't cope with it! Dangerous words and from my point of view I hope the Gooners are all of the same opinion! 2-1 to Wigan. Callum Mac to shine again!"
Every match this weekend is to start seven minutes later than originally scheduled as a mark of respect to the victims of the Hillsborough disaster. It is a fitting tribute on the 25th anniversary of the tragedy and will be particularly poignant here as it was at an FA Cup semi-final against Nottingham Forest in which 96 Liverpool supporters died. The match was halted six minutes after kick-off and there will be a moment's silence before the game to remember those who lost their lives.

Arsenal fan Dwayne Lewis writes: "I'm a Gooner and I'm concerned to be honest the midfield has been a weak link for us recently with no bite, and too much in the way of defensive ineptitude frequently shown in recent results...I'd have preferred to see Kallstrom alongside the undisciplined and limited Arteta with AFC keeping things tight first 45 and earning the right to play with more freedom as opposed to this constant reliance upon so called superior quality in our pattern of play and passing game which has not been anywhere near to required standards for some time! I just pray that there is enough passion and pride and no complacency that creeps into the starting line-up to make sure we gain some sort of advantage as early as possible."
Wigan needed a replay to see off Milton Keynes Dons in the third round but then knocked out Premier League duo Crystal Palace and Cardiff City to reach the quarter-finals, where they produced a wonderful performance to stun Manchester City in a repeat of last season's Wembley showpiece. Arsenal have also had to do it the hard way to reach the last four, defeating North London rivals Tottenham Hotspur, Coventry City, then Liverpool and Everton. Both sides have had a great run, so if they can carry on their FA Cup form we could be in for a classic.
Muhaimen Siddique is a nervous Gooner: "As an Arsenal fan I am scared, the lack of preparation our players are getting we don't know what to do when our opponents know our game plan. We're predictable hence why we've been thrashed by Chelsea, Liverpool, Man City and turned over easily by Everton. I think if the Wigan team that can prepare against City and come out with a result it shouldn't be too hard to do that against Arsenal. If Wigan have done their homework I predict they'll win maybe 1-0. However I'm hoping for a 2-0 win purely based on how well Arsenal can play when things go right for us."
Wigan Athletic may be huge underdogs but they have enjoyed a decent season as they bid to bounce back to the Premier League at the first attempt. Having to juggle their Europa League demands with a Championship campaign was never going to be easy but they have flourished since Uwe Rosler replaced Owen Coyle and look set to finish in the play-off places despite a run of just one win in their last five league matches. Wigan have also revelled in the role of FA Cup champions and mounted a defence of their title they can be extremely proud of, regardless of what happens today.
What do you make of the team news? France Under-21 forward Yaya Sanogo has been handed another chance to impress up front as Olivier Giroud is only named on the bench. Alex Oxlade-Chamberlain has shrugged off a groin problem to start, while Aaron Ramsey comes into the side with Mathieu Flamini suspended and number two goalkeeper Lukasz Fabianski starts again as in previous rounds. Scott Carson has been selected in goal for Wigan, with Marc-Antoine Fortune leading the attack for the holders.
It has been mentioned just a bit over the past few years but, in case anyone isn't aware, it has been quite a while since Arsenal last picked up any major silverware (at least by their standards). 2005 was the last time they won a trophy and the way the big clubs have fallen in this season's FA Cup has only added to the pressure to make sure this chance is not missed. The competition has also taken on extra significance since Arsenal's title chance faded and they are now fighting to finish in the Premier League's top four after losing to Everton last weekend, so Arsene Wenger's position has again come under scrutiny in the build-up to this one.
Chris Green from Huddersfield is the first to get in touch, saying: "Wigan to win 1-0, with McEachran scoring the goal."
Wigan: Carson, Perch, Boyce, Ramis, Crainey, McArthur, McEachran, McManaman, Beausejour, Gomez, Fortune. Subs: Al Habsi, Barnett, Caldwell, Maloney, Espinoza, Collison, Powell.
