Stay with us for report, reaction and plenty more from the Emirates. Thank you for following the action with me this evening.
The final whistle is greeted with boos around the Emirates. A point apiece which Arsenal and United looked happy to take but both sides may look upon it is an opportunity missed later in the season.
United get the chance to break but Rooney runs straight into Koscielny. Poor decision from the United forward.
Carrick attempts to play in van Persie but his pass is too strong. We are into three minutes added time.
Another fine save from De Gea - a dive low to his left to hold on to Cazorla's drive from outside the box.
De Gea is alert again to sprint from his line to dive at the feet of Wilshere after the Arsenal midfielder had burst into the box. Ferdinand did well to ease Wilshere away from the United keeper.
De Gea dives to his right to parry away Cazorla's effort from inside the box after neat interplay with Ozil. Fine save.
Cazorla runs across the United back four and gets in a shot from distance but Vidic is in the way again.
Great save from Szczesny! Van Persie feeds Rooney, who floats a delivery towards the back post for his strike partner, but Szczesny makes a wonderful one-handed save to turn van Persie's header on to the bar.
Great chance for Giroud! Sagna whips a delivery in between De Gea and his defence but Giroud fails to make sufficient contact and the ball drifts beyond the far post.
A change for each side: Rosicky is replaced by Oxlade-Chamberlain in the Arsenal midfield; United's record-signing Mata makes way for Januzaj.
Signs of life on the United bench as Januzaj looks to be getting stripped. Arsenal's Oxlade-Chamberlain is also preparing to come on.
Vidic meets two Sagna crosses in quick succession with firm headers to clear from in front of Giroud.
No signs yet of any further changes as we enter the final quarter of the game. Rosicky gives away a free-kick after a clash with Evra, much to the annoyance of the home supporters.
Mata is penalised for handball and Arsenal have a free-kick wide on the right. Ozil's floats it towards Koscielny at the back post but the delivery is too high and drifts behind.
Mata combines with Cleverley to create a shooting opportunity but the Spaniard pulls his effort from outside the box well wide of the target.
Szczesny comes to the edge of his box to head clear as van Persie threatens to reach Valencia's pass.
Giroud wants a penalty after going to ground, thanks in part to Vidic's push, but Clattenburg is not interested and De Gea gathers Wilshere's deflected cross at the second attempt.
Valencia rescues United by clearing Koscielny's effort off the line. The Frenchman met Ozil's corner with a header that was destined for the net but Valencia leapt to nod clear.
A scrappy period could be seen as evidence of the nervousness in both sides. Valencia does eventually find some space deep on the right but his delivery is woeful.
Evra wins a corner after winning a duel with Sagna. Szczesny punches Rooney's delivery to the edge of the box but Mata's shot is poor and drifts harmlessly wide.
Van Persie bursts into the box in an attempt to combine with Mata but the Spaniard's backheel is cut out.
Ferdinand's long pass lands on the chest of van Persie inside the box but Mertesacker is too strong and intercepts, leaving his opponent on the floor in the process.
Ferdinand's first involvement is to muscle Giroud away from a long ball, allowing it to roll through to De Gea.
Smalling wins an early free-kick wide on the right which Mata delivers. Carrick gets a flick on but no one reads the touch and United have to watch the ball drift harmlessly out for a goal-kick.
Arsenal kick-off, with Smalling moving to right-back for United. Ferdfinand slots in alongside Vidic in central defence.
Matt in Ipswich is not sitting comfortably: 'I'm a very concerned Man Utd fan, just get the feeling that we have lost our way, looking ordinary, got a horrible feeling Arsenal are going to win this 2-1.'
Is it a case so far of both sides preferring to avoid defeat rather than go for the win? United need points quickly if they are to break the top six and eventually the Champions League places, while Arsenal can go to the top of the table. Will that be incentive enough for Wenger to go for it?
David Cassell is content, but wants a change from Wenger: 'Not a bad first half by Arsenal. Ozil so far my star performer. Giroud too slow to latch onto his passes. Arsenal talking too long to shoot. Bring on the Ox in the second half for some pace. Come on Gunners.'
Paul in Lincoln wants more from Arsenal: 'Three points is a must, nothing less will do. Gunners need to bounce back from the Anfield debacle. The next 45 minutes will be decisive. Still feel Arsene should have splashed the cash for a clinical finisher.'
No goals in the first half but both sides had chances early on. United will be encouraged by their display and success in stopping Arsenal's rhythm. Can either side find the killer touch in the second half?
Arsenal start the two added minutes with a corner on the right. Cazorla takes it but it goes over everyone and United clear their box.
United win a corner on the right thanks to Rafael. Mata's delivery, though, is poor and Arteta stoops to head away from the near post.
Arsenal launch a counter-attack which results in Giroud firing in a shot from 20 yards but United recover and block.
Szczesny is careless in dealing with a back-pass, slicing horribly towards the right corner of the box. Van Persie collects, but he, Rooney and Mata cannot combine to break down the retreating Arsenal defence.
The physios are on again, with Rafael in considerable discomfort after landing very awkwardly after an aerial challenge with Giroud. The United full-back came down on the back of his neck but he is now back on his feet and wandering to the touchline.
A spell of high-tempo passing and pressing in the Arsenal half comes to nothing as Carrick goes long but finds only the gloves of Szczesny.
Wilshere needs treatment now after he clashed with Valencia. After a breather, the England midfielder is fine to continue.
United aren't happy after ref Mark Clattenburg halts a United break to get Gibbs some attention after the Arsenal full-back hurt himself in challenging for a header in the United box. Gibbs is ok, but Moyes wants an explanation.
Smalling's clearance gives Arsenal a corner, which Ozil delivers from the left but van Persie heads away from the near post.
Vidic tracks back after Giroud and Ozil break, with the United captain tidying up and Giroud tries to play the ball back inside as he enters the box. Good defending.
Arsenal win a free-kick, to the left of the box, after Cleverley floors Wilshere. Arteta tries to blast a shot towards goal but the wall stands firm.
Ozil breaks after Sagna robs Mata but the German runs down a blind alley and United shepherd the ball back to De Gea.
Rooney loses possession 25 yards from his own goal, allowing Giroud a shot but his attempt from the edge of the D goes high and wide.
Mata shows short and returns the ball to Rooney, who delivers it into the box, but Arsenal again clear.
Giroud heads wide from another corner, with Vidic beaten again. The United defender this time applied enough pressure to deny Giroud an entirely free run.
Rafael wins another corner and Mata again aims for Vidic but Mertesacker leaps higher to win the header and clear.
United counter attack but Cleverley and Valencia combine to completely waste the opportunity. Arsenal recover possession, spread it around and regain their composure.
Wilshere attempts to dink a pass over the United defence for Cazorla but the execution is too heavy and De Gea gathers.
Another chance for van Persie, who springs the Arsenal offside trap to reach Mata's pass, but the United striker opts to cut in on to his right foot inside the box and blasts his attempt well wide.
United enjoy a spell of two-touch in midfield but Evra plays the ball straight out when he attempts to find Mata.
Valencia tries to lob a pass into the path of Rooney, but Mertesacker and Koscielny combine to snuff out the threat.
United are happy to allow Arsenal the ball around the halfway line, leaving it up to the hosts to break them down. Cazorla thinks he has done just that but the linesman's flag is up.
Rafael bursts down the United right and delivers a low cross towards van Persie, who had made a near-post run, but Mertesacker is alert to the danger and gets a block in.
De Gea is called into action again to keep out Rosicky's deflected drive from 25 yards. The United goalkeeper dives to his left and comfortably holds on.
Rooney tests his goalkeeper's touch with a back-pass as two Arsenal forwards close down De Gea, but the Spaniard controls and calmly clears to the halfway line.
United win a corner now, with Koscielny timing a challenge on Rooney to perfection. Vidic goes for the delivery but Arsenal clear.
Giroud misses a free header from seven yards! The Arsenal striker out-muscled Vidic to meet the corner but his attempt drifts wide of De Gea's post. Both sides have missed great chances inside the opening five minutes.
Wilshere takes Ozil's pass before waltzing past Vidic in the box but Smalling gets across to block the England midfielder's shot. Corner to come...
Arteta leaves a mark on Mata and concedes an early free-kick in midfield. Not the best start from the Arsenal captain.
Great chance for van Persie but it is wasted! The United striker robs Arteta and goes one-on-one with Szczesny but the goalkeeper reads his former team-mate, diving low to his left to save.
Evra receives the ball from the kick-off and immediately goes long in an attempt to put van Persie in. Szczesny trots from his line to gather comfortably.
Ozil is saying his pre-match prayers while Arsenal mascot Gunnersaurus looks for someone to play with before he is ushered off the field. United will kick off...
The two sides are emerging from the tunnel. Arsenal, as you'd expect, are in red; United are sporting their blue away kit this evening. There are a fair number of empty seats in the ground.
Alain from Canada has issued a last-minute rallying call for the Gunners: 'This is it for Arsenal. Make or brake, season-defining game. Only a win will do it. Come on Arsenal! Time to show your class.'
Some encouragement for United from John Head - an Arsenal fan: 'It seems a lot of United fans are expecting a hiding from Arsenal, but I can say as an Arsenal fan that we have not been giving a hiding to anyone recently, even lower teams at the Emirates we have found hard to break down. I am confident of a win, but fairly sure it will be by a small margin. No way will we beat United by 3 or 4 nil or beyond!'
Arsenal fans will be hoping for more from Mesut Ozil this evening. Sky Sports' Adam Bate has been looking at the record-signing's current form and has used Opta tracking data to analyse his fading contribution. Check it out here.
Moyes may not be popular with many United fans but Gary Neville believes the manager deserves time to 'tame the Manchester United monster'. Read what the Sky Sports pundit had to say here .
Another United fan not happy with the manager. Philip Lee asks: 'Seriously? No Kagawa again? Moyes seems to hate him for some reason. He's by far our best number 10. We haven't been playing well all season and he still persists with the same boring tactic of lumping the ball in the box.' Has Kagawa really shown enough in his few performances to warrant inclusion?
The two sides are warming up on the lush Emirates pitch. Fans are filtering in slowly, but many United supporters were left stranded around Manchester by train cancellations. United were earlier today calling London-based fans who missed out in the ticket ballot to offer them the chance to go this evening. The London Underground strike was averted yesterday but many did not see foresee these weather problems.
Not a lot of love out there for Cleverley. Tyler from Kettering asks: 'Why is Cleverley starting!!!! Would rather Fellaini. TC is not good enough, I would even rather bringng back Djemba-Djemba!' Put a call into St Mirren, maybe a loan deal could be arranged!
Of course, Robin van Persie returns to the Emirates and United need him and the likes of Rooney and Mata to be on top form if they are to get a positive result. According to Opta, Arsenal have kept 10 clean sheets in their last 11 matches in all competitions at the Emirates Stadium and conceded just one in the other game. However, we also know van Persie has scored in each of the last five meetings between these two teams - the first two times for Arsenal and the last three for United.
A few of you are backing the Gunners. Chris Green says: 'Arsenal to win 4-0, with Arteta, Ozil (2) and Giroud scoring the goals.' Dan is equally certain of a home win: 'No doubt about it, Arsenal will get the three points. It's there time to shine as real contenders and with United's leaky defence I can't see them keeping Arsenal at bay, especially at the emirates! 3-1 Arsenal. Ozil to have a blinder!' Sibbo seems confident: 'I think Arsenal will wipe the floor with Man Utd tonight and go top off the Premier League again. Come on you Gunners 4-1'
Sophie Connolly is finding United's current form tough to take, but she's not pinning the blame entirely on the manager: 'If we don't start improving I'll go insane. We can't keep blaming Moyes, players don't look like they are bothered anymore. Hopefully a win tonight will set the tone for the remainder of the season! 2-1 United, Van Persie and Mata for United, Giroud for Arsenal! Come on the Red Devils!'
United fan Steve Anderson isn't happy at the inclusion of Cleverley: 'What is Moyes thinking???? Cleverley in the team for such an important game? Sorry, he did have promise when he was younger, but he has done NOTHING since - definitely not Man Utd class. I would have chosen an unfit Fellaini over Cleverley any day.' Not a fan of TC23, I gather.
Both managers make two changes from the weekend. Wenger brings in Gibbs and Rosicky for Monreal and Oxlade Chamberlain; Moyes opts to go with Cleverley and Valencia over Fletcher and Young. Are they the right calls?
The two benches: Arsenal: Fabianski, Jenkinson, Monreal, Oxlade-Chamberlain, Podolski, Sanogo, Bendtner. United: Lindegaard, Buttner, Ferdinand, Fellaini, Young, Hernandez, Januzaj.
Manchester United: De Gea, Rafael, Smalling, Vidic, Evra, Cleverley, Carrick, Valencia, Mata, Rooney, van Persie.
Arsenal: Szczesny, Sagna, Mertesacker, Koscielny, Gibbs, Arteta, Wilshere, Rosicky, Ozil, Cazorla, Giroud
Mark Carter from County Durham is a United fan of 38 years but he's not expecting a point tonight: 'I've followed United through thick and thin but I'm afraid with Moyes we are playing like a Championship team and the players are heartless and have no fight left. My prediction tonight is a good hiding from Arsenal, it will be an embarrassment for every United fan. Arsenal will destroy us.'
A couple of early predictions, and both Lewis Spiby and Dhanyal Javed are sitting on the fence. Lewis says: 'I can see this one being a 2-2 draw, I actually think Man United might play quite well tonight, I think Mata might score as well.' Dhanyal also fancies Mata to impress and even get on the scoresheet in a 1-1 stalemate.
The weather is playing havoc across the UK today, with many United fans facing chaos in their attempts to travel south today. This game goes ahead, at least - the Manchester City v Sunderland clash does not. Have the storms affected your plans to attend the game?
We know Arsenal will be missing Mathieu Flamini, Aaron Ramsey, Kim Kallstrom and Thomas Vermaelen. United also have injury concerns, with Phil Jones and Marouane Fellaini both out, while Jonny Evans is also a major doubt. Might there be a recall for Rio Ferdinand?
The team news is expected to be confirmed around 6:45pm, when we will see whether or not Moyes and Arsene Wenger have felt the need to shake things up after forgettable weekends for both sides. Arsenal were thrashed 5-1 at Liverpool, while United were held to a 2-2 draw by Fulham despite dominating the Super Sunday affair.
How do you see it going? I'd like to hear your predictions and opinions throughout the evening. You can reach me on email firstname.lastname@example.org or find me on Twitter: @IanWatson1.
There is plenty at stake for both sides at the Emirates, with Arsenal hoping to return to the top of the Premier League table. Champions United can only dream of such an achievement this season and David Moyes' side desperately need the three points to close on the gap on the top six and restore some confidence.
