Swansea and Arsenal must meet again at Emirates Stadium to decide who progresses to the fourth round. Stay with us for a full match report and all the key reaction.
Tiendalli wastes a glorious chance to put Swansea back in front after being found by Graham, tamely shooting into the side-netting with team-mates free in the middle.
SUPERB SAVE FROM VORM!! Walcott's corner is met by Koscielny's powerful header, but the keeper makes an excellent save, before the Arsenal man fires his follow-up off target.
Walcott looks to get away from Chico, but Bartley comes across to clear as the Arsenal man goes to ground. Corner to the Gunners.
Agustien's corner goes all the way through to Ki, with his pass finding Graham and the striker makes no mistake with a neat far-post finish.
Now Swansea are chasing the game, with Ki forcing Szczesny to parry away his curling effort before the home side force a corner.
Stunning volley from Gibbs to fire Arsenal into the lead, leaving Vorm with no chance after playing a one-two with Giroud and being allowed to race into the box.
Great finish from Podolski to get Arsenal back on terms. Walcott's deep corner is met by Gibbs, with Koscielny then turning the ball back into the box for Podolski to find the bottom corner with a neat shot on the turn.
Wilshere is sent cartwheeling on the edge of the Swansea box by Bartley, with the yellow card immediately out.
Podolski may be slightly relieved to see the offside flag go up after he shoots wide of Vorm's goal from only eight yards out.
Walcott inches away from levelling as some poor defending from the Swans gifts him the opportunity, but he flashes his shot across Vorm's goal and narrowly wide of the far post.
Cazorla attempts a one-two with Wilshere in the Swansea box, but the England midfielder lets the ball run under his foot and out for a goalkick.
Arsenal have finally sparked into some kind of action after falling behind, and Cazorla's clever ball into the area causes a degree of confusion before Swansea clear.
Great work from Ramsey to create space for a cross near the corner flag. His delivery to the edge of the six-yard box is perfect for Giroud, but he gets his header all wrong and misses the target. Bad miss.
Poor play from Cazorla gives the ball to Graham, he feeds Hernandez who works some space and attempts to clip a cross to the far post only to find Szczesny.
Great defending from Tiendalli to slide in and deny Gibbs as the Arsenal man broke into the box, he had to time that one perfectly. The resulting corner comes to nothing.
Ki clips the ball in towards the near post, but it's a poor effort and Giroud, who now appears to have recovered, heads clear.
Arsenal have slipped to 6/1 to win this game, with the Swans now 8/15 on after Michu's opener. The game is 9/4 to finish 1-0, while a 1-1 draw can be backed at 11/4. Giroud and Walcott are each 6/1 favourites to score the next goal.
Awful defending from Arsenal as Vorm's long kick is headed on by the diminutive Dyer, before the Arsenal centre-backs are left all at sea as Graham feeds Michu, with the substitute racing clear to beat Szczesny with a cool low shot.
Davies gets away with a poor first touch, almost gifting possession to Walcott, but recovers well to clear.
Double change for the home side, with Wayne Routledge making way for Pablo Hernandez and Michu coming on for Jonathan De Guzman. Giroud has now limped to the sidelines.
Vorm is forced into action again, making a smart stop from Giroud's volley from Gibbs' cross. The Frenchman is down and looks in some distress after catching Chico as he shot.
Penalty appeals from Arsenal are waved away by Howard Webb as Ramsey goes to ground as he cuts across Tiandelli. Replays show the ref was spot on, as the Gunners midfielder tripped himself up.
Good save from Vorm to deny Giroud. Arsenal finally break at pace with Cazorla finding Walcott, whose pass is met with a low first time strike by the Frenchman, which is blocked by Vorm.
Poor clearance from De Guzman goes up in the air and puts Swansea under pressure, with Giroud finding Ramsey before Britton slides in.
Swansea get us under way at the start of the second period. Let's hope for an improvement from the first 45 minutes.
Sky Bet's half-time price boosts include Arsenal to win 2-0 at 9/1, while a Danny Graham winner in a 1-0 victory for the Swans is available at 40/1. It hasn't been a classic so far by any stretch of the imagination, and you can back this one to end up goalless at 10/3.
Referee Webb brings the half to a close. In a match lacking any real fizz, Bartley's header which came back off the top of the bar was the closest either side came.
Vorm is forced into making a save as the half draws to a close, dropping to his left to gather Cazorla's low shot on the turn from outside the area.
Good attack from Sagna as he charges forward and exchanges passes with Walcott, before Chico blocks his attempted cross.
Wilshere wins a free-kick from Ki near the halfway line, but Arsenal's next attack comes to nothing.
Great defending from Chico as he keeps pace with Walcott and then eases him off the ball as the Arsenal forward attempts to get away.
That is the closest we have been to the deadlock being broken, with Mertesacker beaten in the air by Bartley.
OFF THE BAR!! Swansea so close to taking the lead as Bartley's header from De Guzman's free-kick bounces off the top of Szczesny's goal.
Finally, a shot (just about) worthy of the name from Arsenal, but Cazorla's effort from Gibbs' low cross is high and over the bar.
Davies does well to dig out a cross on the left and find Dyer. His attempted shot is blocked before De Guzman runs the ball out when attempting to beat his man.
Almost an opening for Arsenal there as Ramsey twists and turns to work space for a shot in the box, only to see Davies slide in with a vital tackle as he prepares to pull the trigger.
Long spell of Arsenal possession and passing ends when Arteta's clipped cross into the box is well off target of any of his team-mates.
Arteta attempts a long ball over the top towards Ramsey, but there is too much weight on the pass and Vorm gathers on the edge of his box.
Great reverse diagonal pass from De Guzman to set Dyer away, but Arteta tracks his run well and Swansea are forced back.
Walcott runs at the Arsenal defence and is felled by Chico, Webb lets play go on, but then awards the free-kick just outside the area as there is no advantage. Danger here.
Graham chases down another long pass out of defence, but Szczesny is alert to the danger and clears from outside his box.
Not a great clearance by Vorm, but he is rescued by Davies and Swansea go on the attack again before Sagna comes across and concedes a corner.
Routledge tangles with Sagna down the left, with the Swansea man pulled up for tripping the Arsenal man.
Another dismal free-kick from Wilshere. The Arsenal midfielder only finds Vorm once again from a promising position out on the right after Chico's handball as Walcott attempted to go past him.
Good chance for Swansea, as a long ball out of defence is controlled by Graham before he unleashes a powerful shot from outside the box which Szczesny dives to push away. Best opportunity of the game so far.
Davies is penalised for holding Walcott some 35 yards out, but Wilshere's free-kick is poor and Vorm gathers with ease.
Walcott is freed down the right but his cross has far too much power and goes all the way out for a throw on the far side of the pitch.
Dangerous attack from Swansea, with Dyer, De Guzman and Tiendalli combining, with the cross from the latter headed away by Sagna around the penalty spot.
Wilshere attempts a long ball forward towards Giroud, but overhits it badly and it goes into Vorm's arms.
Swansea attack again and Davies completely mishits a shot from outside the box, but the offside flag is once again raised.
Walcott looks to get in behind Chico, but the Swansea defender holds off the fleet-footed Gunners forward.
Swansea earn a throw near the corner flag on the right, but make a mess of their passing and the offside flag goes up.
Play switches to the other end and Routledge crosses into the area towards Graham, but Szczesny gathers above the Swans forward.
First chance for Arsenal, with Wilshere flighting a dangerous free-kick into the box, which is smuggled behind for a corner with Giroud lurking, with the Swans then clearing their lines.
Easy to tell whenever Aaron Ramsey has the ball, with the former Cardiff man getting the reception you would expect in Swansea.
Patient start from both sides, as you would expect given their football philosophy, with possession important.
There is an opportunity for Danny Graham to stake his claim for regular action with Swansea today, or put himself in the shop window for a possible January move. Sunderland, Norwich and Reading have all been linked.
Final opinion before we get under way comes from @mrstef_l, who says: 'I'm going with 3-2 to Swansea with Arsenal taking the lead but then losing it!'
Liam Ryan from Ardcroney, Tipperary, Ireland says: 'Hoping for a Arsenal win 2-1 - Walcott and Cazorla - January is a daunting looking month with games against Man City, Chelsea, West Ham and Liverpool to come - must not lose today!!'
Ashley Baldock writes: 'After looking at the team that Arsenal have put out it's going to be a tough one for the mighty Swans. But with the likes of Michu and Graham in the side, with their skill on and off the ball I can see Arsenal struggling. I'm going for a 3-1 Swansea win today. Stop the Gunners getting any silverware again this year!!'
Opta stat No.4: This will be the fourth FA Cup tie between Swansea and Arsenal, but the first since 1968. Swansea won the first meeting between the sides in 1926 but have since lost the last two.
Opta stat No.2: In 19 previous FA Cup ties with teams from the same division, Swansea have progressed just four times and on neither occasion in the last three years.
Opta stat No.1: Swansea have won their last two Premier League matches against Arsenal, 2-0 at the Emirates in December and 3-2 at the Liberty Stadium last January.
Another score prediction, this time from a young supporter: 'My name is Thomas. I'm an 8-year-old Gunners fan and I'm going with 3-0 Arsenal with a Giroud brace and Arteta with a penalty.'
@osahiuzouwaifo reckons: 'I'll go for a 3-1 win to Arsenal though it will be a close match statistically. I think they're hungry enough to win.'
@JamieMcVeigh1 writes: 'Looking forward to seeing Ramsey start, it's a great opportunity for him to answer his critics having been so put down by them.'
Wales midfielder Aaron Ramsey has been handed a start for the Gunners, with Per Mertesacker coming in for Thomas Vermaelen in defence and Olivier Giroud preferred to Lukas Podolski in attack.
Here's more news on today's teams, with Swansea manager Michael Laudrup leaving top scorer Michu on the bench. The 14-goal Spaniard makes way with Laudrup shuffling his pack ahead of Wednesday's Capital One Cup semi-final first leg at Chelsea as Dwight Tiendalli, Kyle Bartley, Ki Sung-yueng and Nathan Dyer all come into the starting line-up.
@ricketts999 writes: 'Gunners should take this 2-1. Walcott with a late winner. Swansea will put up a fight. And Arsenal need to win something!'
Sky Bet have a range of price boosts ahead of kick-off, including Swansea to win 2-1 (11/1 from 10/1). Other boosts include the Gunners to win 3-1 (16/1 from 14/1) and Wilshere to open the scoring at 22/1. In our outright betting market, Arsenal are the 21/20 favourites, but the hosts are well backed for the win at 5/2.
Mike Bayes from Doncaster says: 'Got a feeling this will be start of turn around for Arsenal - expect Wilshere to have a massive influence trying to strangle Swansea midfield plus Michu a big miss for Swansea.'
And Gabriel Sutton reckons: 'I have a feeling that the FA Cup finalists this year will be Man City and Arsenal. Arsenal may need the cup if they can't get 4th and a trophy would be an important boost for them so I reckon they'll win this comfortably in the end. 0-2.'
Next up is Riff from Cardiff, who says: 'I can't see Arsenal getting anything from this game, I'm going for a 2-0 Swans win with a Graham brace. COYS:)'
First person to get in touch is @James92Gregory, who says: 'Swansea should have this 2-1 but Michu will be missed.'
