The action continues due to a few late knocks, with Bailly struggling with cramp and Lichsteiner now having some attention from the medical team.
90' +3
The stands are starting to empty at Old Trafford and the tempo of the game has decreased significantly as the clock ticks towards the final whistle.
90' +1
There will be four minutes of added time at the end of the second half.
89'
Lacazette nods the ball out of De Gea's clutches, as he was only holding it with one hand, before tucking into the empty net but the official pulls the play back.
88'
Arsenal, who will still be tired from an intense North London derby at the weekend, seem to have lost their string in the past few minutes and it appears they are content with the score as it stands.
86'
L. Torreira gets yellow.
Torreira picks up a booking for a poor challenge in the build-up to that Rashford chance, which was not his first infringement.
85'
Leno forced into a save by Rashford's drive from distance but it was not a convincing one. United certainly look the more likely to snatch a winning goal at the moment.
83'
Not too sure either side will be happy with the score as it stands. Arsenal would extend their unbeaten run to 20 matches but may feel this was their best chance to end their recent poor record at Old Trafford, while United would be without a win in four Premier League matches.
81'
Into the final 10 minutes and Arsenal look exhausted. Manchester United certainly have the fresher legs as the Gunners were forced into changes earlier than they would have liked through injury.
Minute
Description
79'
It has been a very strange game at Old Trafford. Neither side has actually been good for extended periods and there also has not been too much in the way of clear-cut opportunities. Despite that, we have seen four goals.
77'
Arsenal will certainly be wondering how they do not lead after those chances for Aubameyang and Mkhitaryan but it is at least encouraging. Kolasinac is finding all sorts of space down the left, with Dalot struggling to keep him at bay.
75'
P. Pogba enters the game and replaces J. Lingard.
Aubameyang has found much more joy since moving into a wider position following the introduction of Lacazette, curling an effort at goal from distance that requires De Gea to palm away with a diving save.
Third and final change for Manchester United, as Pogba takes to the field for the final 15 minutes to take the place of Lingard.
74'
The match is very delicately poised and both defences look vulnerable. There is still goals in this game.
72'
M. Fellaini enters the game and replaces M. Rojo.
Another change for United as Rojo, who is fortunate to be on the field having already been booked before diving in on Lacazette for Arsenal's second, is replaced by Fellaini.
69'
J. Lingard has scored a goal for Manchester United!
GOOOOOAL! 2-2! United equalise immediately! Sloppy defending from Arsenal sees everyone asleep at the back and Lingard takes advantage, poking the ball past Leno to spark the home fans back into life.
68'
M. Rojo is unfortunate, scores an own goal!
GOOOOOAL! 2-1 Arsenal! The Gunners retake the lead! Rojo sloppily concedes possession to Mkhitaryan, who combines well with Lacazette to burst through on goal. Rojo charges back to clatter into the striker and ends up diverting the ball off Lacazette. A very fortunate goal.
67'
A very even game as we edge towards the latter stages, with both teams having the capability to snatch a late winner. However, neither side currently looks like they have the creativity to break through the opposing defences.
65'
A. Lacazette enters the game and replaces A. Iwobi.
Third and final change for Arsenal sees the introduction of Lacazette, who takes the place of Iwobi.
63'
R. Lukaku enters the game and replaces A. Martial.
Martial is unable to continue, becoming the third player in the match to be forced off by injury, and Lukaku enters the game as his replacement.
61'
Inside the final half hour at Old Trafford and Arsenal are looking short of ideas at the moment, unable to find a way through a resilient United defence.
59'
The Red Devils continue to push forward with intent and Rojo fires a shot from distance towards goal, which Leno tips over the bar for a corner. The delivery is headed down into the ground by Mustafi and bounces up to hit an arm, leading to cries of handball.
57'
United are starting to look like the better team at the moment but clear-cut chances are few and far between. The home supporters have raised the noise levels though to urge their side forward.
52'
Rashford finds space inside the box but cannot find Lingard in the middle as Mustafi slides in to put the ball behind for a corner, which Leno punches away from danger.
50'
The hosts are being pegged back inside their own half in the early stages of the second period and they too will be looking for improvements as they have not created much from open play.
48'
Arsenal start the second half strongly, controlling the tempo, and Emery will certainly have been urging the side to get Aubameyang on the ball more. Their top scorer is yet to cause problems.
46'
H. Mkhitaryan enters the game and replaces A. Ramsey.
Confirmation that Arsenal were forced into a change at the break as Ramsey is replaced by former United man Mkhitaryan.
United get the action back underway for the second period.
45' +3
HALF-TIME: MANCHESTER UNITED 1-1 ARSENAL
45' +1
The fourth official has signalled for three minutes of additional time at the end of the first half.
42'
N. Matić gets yellow.
And now Matic joins the fun! He pulls Aubameyang from behind to prevent a counter attack, giving the officials an easy decision.
41'
Héctor Bellerín gets yellow.
Bellerin continues the trend of bookings for a foul on Darmian. There is certainly an edge developing in the game.
40'
J. Lingard gets yellow.
The flurry of yellow cards continues as Lingard clips Torreira from behind in midfield, having his name taken by Andre Marriner as a result.
38'
M. Rojo gets yellow.
Arsenal are furious as the free-kick comes to nothing but Rojo charges in furiously with a poor challenge on Guendouzi, who picks up a booking but the visitors believe he deserved to be dismissed.
37'
S. Mustafi gets yellow.
Rashford bursts past Lichtsteiner and Mustafi slides in with a strong challenge, conceding a free-kick and earning the game's first yellow card.
36'
S. Lichtsteiner enters the game and replaces R. Holding.
A huge blow for Arsenal as Holding is stretched off, with Lichtsteiner entering the frame as his replacement.
30'
A. Martial has scored a goal for Manchester United! Assist by Ander Herrera.
GOOOOOOOAL! 1-1! The lead did not last long! Rojo forces a diving save from Leno but Herrera prevents the ball from going behind for a corner. He cuts a pass back into the middle where Martial smashes home an equaliser.
Herrera was not quick enough at the other end to stop the ball from crossing the line but he does the job there. However, replays showed he was slightly offside and Arsenal will feel aggrieved.
29'
Guendouzi catches Martial from behind a few yards outside the area and United have a free-kick in a dangerous position.
28'
A big test for Manchester United now, although you have to feel they will get opportunities as Arsenal's defence has not looked too strong so far this season.
26'
S. Mustafi has scored a goal for Arsenal! Assist by L. Torreira.
Torreira's delivery was nothing special but it proved to be effective. Arsenal do not score often from set pieces but they hold a valuable lead here.
GOOOOOOAL! 1-0 Arsenal! Torreira whips a corner into the middle and Mustafi latches onto the end of his delivery to head at goal. De Gea parries the ball up in the air and it drops on the line, where Herrera attempts to clear but the goal decision system says he was not quick enough.
25'
United continue to find themselves on the back foot and it will be interesting to see at what point the home fans start to get frustrated.
23'
The Gunners sweep down the left side once again, which is becoming an area of focus in their attacking moves, but Kolasinac is flagged offside.
21'
Arsenal have started to establish a foothold on the match during the past 10 minutes but De Gea is yet to be tested and United's defence has not really been stretched.
17'
Torreira drills the ball into the middle where Aubameyang is lurking but United's defence does enough to quell the danger, with De Gea collecting the ball and attempting to start an attack.
15'
Kolasinac unleashes Iwobi down the left and Arsenal win their first corner of the game as Bailly deflects the ball behind.
13'
Manchester United have certainly made the better start in the match but there have not been any clear-cut chances for either side so far.
11'
A better period in the game for Arsenal but Aubameyang, the Premier League's top scorer so far this season, has not seen much of the ball in dangerous areas.
7'
The Gunners are starting to find some rhythm in possession and are moving the ball around to ease the pressure they have faced in the early exchanges.
5'
Arsenal's shaky start continues as United work their way through the gears and Rashford tests Leno early on, though his shot from distance is straight at the Germany international.
3'
United have started the game with plenty of intensity and Arsenal have been unable to get the ball out of their own half during the first few minutes.
1'
We are underway at Old Trafford, where Arsenal get the action started.
Hello and welcome to our LIVE coverage of the Premier League clash between Manchester United and Arsenal, where two giants of English football collide.
Arsenal enter the game full of spirit after their victory in the North London derby at the weekend, while Manchester United needed to do some soul searching after fighting back from two goals down to draw with Southampton. The pressure is on the hosts though, who will fall 11 points behind the top four if they lose here.
Man United subs: Sergio Romero, Romelu Lukaku, Maroaune Fellaini, Paul Pogba, Antonio Valencia, Juan Mata, Scott McTominay.
Manchester United XI (3-4-2-1): David De Gea; Eric Bailly, Chris Smalling, Marcos Rojo; Diogo Dalot, Nemanja Matic, Ander Herrera, Matteo Darmian; Jesse Lingard, Anthony Martial; Marcus Rashford.
Arsenal XI (3-4-2-1): Bernd Leno; Rob Holding, Sokratis, Shkodran Mustafi; Hector Bellerin, Lucas Torreira, Matteo Guendouzi, Sead Kolasinac; Aaron Ramsey, Alex Iwobi; Pierre-Emerick Aubameyang.
Arsenal subs: Petr Cech, Mohamed Elneny, Henrikh Mkhitaryan, Stephan Lichtsteiner, Alexandre Lacazette, Eddie Nketiah, Ainsley Maitland-Niles.
The two teams are heading onto the field ahead of the start of what should be a very exciting match.
An entertaining first half at Old Trafford, where Mustafi handed Arsenal the lead but it did not take long for Martial to tuck home an equaliser. The game soon developed into a fiery one with a flurry of yellow cards and it leaves a number of players walking a tightrope for the remainder of the match.
United started strongly before dipping away, with Arsenal controlling the tempo of the game. If it remains that way, the Gunners will be favourites to secure a win but Emery has concerns having already lost Holding to injury and seeing Ramsey pick up a problem. At this rate, United may need to look to the bench for inspiration.
Thanks for joining our coverage for this match. Until next time, goodbye.
United are now without a win in four Premier League matches and will be under pressure to end that streak when they host Fulham at the weekend. Meanwhile, Arsenal are now unbeaten in 20 matches across all competitions, their best run since 2007, and welcome Huddersfield to the Emirates Stadium on Saturday.
