That's it! Marouane Fellaini's injury-time header has sealed the three points for Manchester United against this inexperienced Arsenal side. With that, United have secured second place in the Premier League while Arsenal are definitely finishing outside of the top four - their only route into the Champions League next season is to win the Europa League, and they have the chance to do so on Thursday when they face Atletico Madrid in the second leg of their semi-final. Manchester United 2 - 1 Arsenal.
90'
CHEEKY
The United fans are at it again - "Arsene Wenger, we want you to stay".
90'
THIS ONE COUNTS
Arsenal look gutted - and as well they might. The Gunners do a poor job of clearing a corner and Ashley Young gets a second bite of the cherry, whipping in a curling cross. Marouane Fellaini cushions his header into the top corner and David Ospina is inches away from getting to it - but not close enough. Manchester United 2 - 1 Arsenal.
90'
GOOOOOAAAAALLLL
SURELY THAT'S THE WINNER?
90'
ADDED TIME
Four minutes are added on.
90'
Goal
Marouane Fellaini. Assist by Ashley Young (Manchester United)
89'
GOOOOOAAALLL - OR NOT
It's almost a carbon copy of the first goal, but it's ruled out! Anthony Martial swings in a superb cross from the left and Marouane Fellaini times his run to perfection, only to watch his header cannon back off the post. Marcus Rashford is on hand to turn it in, but is rightly ruled offside.
88'
ANOTHER INJURY
It's Granit Xhaka who's down again, but it looks like cramp.
87'
GOOD DEFENDING
Chris Smalling has to stretch every muscle to clear the ball - Joe Willock races forward and plays it forward to Danny Welbeck, only for Smalling to cut it out.
86'
OUCH
Alex Iwobi tries to race on to the end of a long ball but clutches at his hamstring - he's in some pain but Arsenal have no substitutions left.
84'
WARNING
Marouane Fellaini has put himself about since coming on and earns a stern talking-to from the referee - no booking as yet.
83'
NICE TRY
Anthony Martial lays the ball to Ashley Young on the overlap, but he watches on in despair as Antonio Valencia smashes his volley over the bar from Young's superb cross.
82'
APPEAL
Marouane Fellaini looks pleadingly at the referee as he wants a penalty for a shove in the back. Nothing doing.
79'
PRESSING
It's United who are looking for a second goal at the moment, but they aren't giving David Ospina too much to do. Still over 10 minutes to go for a twist.
76'
Substitution
Joe Willock (on). Henrikh Mkhitaryan (off). (Arsenal)
76'
ARSENAL CHANGE
David Ospina should be ok to see this game out, as Henrikh Mkhitaryan departs the field for 18-year-old Joe Willock.
75'
WARM UP
Joe Willock is warming up and ready to come on, but then David Ospina takes a knock and Petr Cech is summoned to do a warm up of his own. Could we see a goalkeeper change?
74'
NARROW
This game has been played through the middle - neither side seems keen to play the ball out wide. Maybe the likes of Anthony Martial can change that?
71'
PRESSURE
Anthony Martial sends in a wicked cross from the left and Konstantinos Mavropanos makes a superb clearance to prevent Marouane Fellaini getting on the end of it. The young Greek defender has looked impressive today.
69'
EFFORT
Marouane Fellaini hesitates on the ball and Danny Welbeck takes it from him before firing a shot down the throat of David De Gea.
67'
STALEMATE
All of the substitutes are taking their time to bed in and the game has slowed as a consequence. Still over 20 minutes for something to change.
Jose Mourinho goes all in, swapping Anthony Martial and Marouane Fellaini for Ander Herrera and Jesse Lingard. Arsenal, meanwhile, replace Sead Kolasinac and Reiss Nelson with Nacho Monreal and former United man Danny Welbeck.
61'
OPENING UP
Neither side wants to lose this game - both need a win to secure the best position possible - second place for United and the possibility of the top four for Arsenal.
58'
POOR
Ashley Young brings down Henrikh Mkhitaryan in a dangerous position and Arsenal have a free kick. Granit Xhaka steps up to swing it to the far post but it sails over the top.
54'
ANOTHER WORRY
Granit Xhaka is now down and clutching his ankle for Arsenal. He isn't one to go down without just cause and he signals he wants to continue.
51'
Goal
Henrikh Mkhitaryan. Assist by Granit Xhaka (Arsenal)
51'
OUT OF NOWHERE
I didn't see this coming! Granit Xhaka refuses to give up on a loose ball and chases it round the middle of the park, eventually winning it back and playing it forward to Henrikh Mkhitaryan. The former United man looks up, notices a gap, and fires a low effort past David De Gea, before celebrating in a muted manner. Manchester United 1 - 1 Arsenal
51'
GOOOOAAAAALLLL
AND ARSENAL HAVE AN EQUALISER!
6'
NOT MUCH TO SAY
It's been a quiet start to this game. Paul Pogba had a half-chance a moment ago but shanked his effort wide. Early days yet.
64'
Substitution
Anthony Martial (on). Ander Herrera (off). (Manchester United)
64'
Substitution
Danny Welbeck (on). Reiss Nelson (off). (Arsenal)

Substitution

OFF TARGET
Pierre-Emerick Aubameyang is forced wide but he still manages to get a cross in - Reiss Nelson sends his header well wide.
41'
OFF THE POST
Ashley Young rattles the post! Paul Pogba picks him out with a superb ball out wide and the defender flashes a ball into the box, which comes off the post. Cross or shot? Only he'll know.
38'
ATTEMPT
Alexis Sanchez plays the ball through to Romelu Lukaku, who can't get it out from under his feet allowing the Arsenal defenders to swarm on him.
36'
POOR
A good ball comes in from the right, and Pierre-Emerick Aubameyang can't get enough power on it to trouble David De Gea.
34'
NICE TRY
Henrikh Mkhitaryan and Pierre-Emerick Aubameyang swap passes on the edge of the box, but the Armenian is robbed and United clear. Arsenal don't look like they are going to give up on this one.
31'
APPEAL
Henrikh Mkhitaryan goes down in the box under pressure from Chris Smalling and Paul Pogba - he wants a penalty but he doesn't get one.
28'
MISSING THE FINAL BALL
Arsenal are starting to come forward, looking for gaps in the United back-line, but they can't quite find the final ball.
24'
Yellow Card
Granit Xhaka (Arsenal)
24'
BOOKING
Granit Xhaka grabs the shoulder of Jesse Lingard and hauls him back, earning the first yellow card of the game.
3'
DEBUT BOY
Konstantinos Mavropanos is making his debut for Arsenal today, having signed for the club in January. What a place to do it.
22'
NOT MUCH TO REPORT
Manchester United look comfortable without threatening, Arsenal look inexperienced - which I guess they are.
19'
MOCKING
The home fans have a bit of a sense of humour - "Arsene Wenger, we want you to stay" rings around Old Trafford.
17'
MISTAKES PUNISHED
Well, could this be the floodgates opening? Jesse Lingard robs the ball in midfield before finding Paul Pogba, who saunters forward with no challenge coming. Pogba picks out Romelu Lukaku on the right, who bends in a superb cross for Alexis Sanchez at the back post. His header comes back off the post, but Pogba is there to poke home for a very easy goal. Manchester United 1 - 0 Arsenal.

INTERESTING SELECTION
Wenger received a standing ovation from all sides of the ground as he appeared earlier - and I'm sure that at least a small part of it, from the United fans at least, is for his team selection today. It's safe to say this isn't Arsenal's strongest line-up.
14'
SWAPPING SIDES
Don't forget, both Alexis Sanchez and Henrikh Mkhitaryan are playing against their former sides for the first time today. I don't think either of them have had a sniff so far.
11'
QUIET
I haven't said anything because...there hasn't been much to say. It's been throw-ins aplenty for the last few moments.

KICK OFF
Arsene Wenger's potential last ever game against Manchester United is underway.
0'
MAN IN THE MIDDLE
Leicestershire official Kevin Friend takes charge of this game, having shown 60 yellow cards and one red in 30 previous games this season. Man Utd have won both of their previous games with him in charge this season, both by a score of two goals to nothing and both games without a caution. Arsenal have won two and lost one of their games under Friend this season, picking up just two bookings in the process.

ARSENAL TEAM NEWS
Unlike his counterpart, Arsene Wenger makes a whole host of changes as his team played Atletico Madrid just three days ago. Konstantinos Mavropanos, Calum Chambers and Sead Kolasinac all come into defence, with Ainsley Maitland-Niles, Henrikh Mkhitaryan, Reiss Nelson, Alex Iwobi and Pierre-Emerick Aubameyang all taking slots further up the field. Only Hector Bellerin, Granit Xhaka and somewhat surprisingly David Ospina keep their places.

MANCHESTER UNITED TEAM NEWS
Jose Mourinho makes just one change to the side that beat Tottenham in last week's FA Cup semi-final - Victor Lindelof replaces Phil Jones in defence. Former Arsenal man Alexis Sanchez starts against his former club for the first time.
0'
PERMUTATIONS
We're at the stage of the season where every result has a clear impact on the final table. A win for Manchester United would secure a second-place finish in the Premier League. Anything other than a win for Arsenal would mean that they are definitely out of the top four. Mark my words, both sides are going to be giving this one everything.
0'
FORM GUIDE
Manchester United are in the better form of the two, losing just one of their last six scoring 11 and conceding four in the process. Arsenal, on the other hand, have three wins, two draws and one loss in the same period, scoring 15 and letting in nine.

PREVIEW
The Arsene Wenger farewell tour continues as he takes on two of his biggest rivals from his time in the Premier League – Manchester United, and their manager Jose Mourinho. This match may not be for the title, like in previous years, but this is still a rivalry that burns bright as ever – don't expect any punches to be pulled.
49'
UNITED CHANGE
As expected, Romelu Lukaku limps off the field and Marcus Rashford takes his place. Is that a worry for Jose Mourinho with the FA Cup final on the horizon? And for Lukaku himself with the World Cup this summer?
48'
WORRY
Romelu Lukaku is limping having taken a heavy challenge a few moments ago. Marcus Rashford is now warming up and it looks like Lukaku's afternoon is over.
48'
SURGING
Ainsley Maitland-Niles breaks from midfield, finds a space and tries to shoot. His effort is blocked and United clear.
46'
KICK OFF
The second period is underway.
45'
HALF TIME
That's it. Paul Pogba's tap-in separates the two sides at the break. Manchester United 1 - 0 Arsenal.
