Arsenal ensured that the race for Premier League glory would go down to the final day thanks to a scrappy 1-0 win over Manchester United at Old Trafford.
Neither the Red Devils nor the Gunners were at their best at the Theatre of Dreams, but some lackadaisical Red Devils defending allowed Leandro Trossard to strike the first and ultimately crucial goal in the first half.
Erik ten Hag's men huffed and puffed in the second half, but a combination of staunch Arsenal defending and a lack of killer instinct from the hosts saw the Gunners complete their first Premier League double over the Red Devils since the 2006-07 season.
Mikel Arteta's men now boast a one-point lead over Manchester City before the champions clash with Tottenham Hotspur on Tuesday, while the Red Devils remain eighth, three points shy of Chelsea and Newcastle United for a European berth.
The 4.30pm kickoff may be the only English top-flight game on Sunday's menu, but it is one that stands alone thanks to the plethora of historic battles, such as the 8-2 demolition of 2012 or Arsenal's title-clinching 1-0 success 10 years before.
Can the European-chasing Red Devils atone for Monday's harrowing 4-0 loss at Crystal Palace, or will Arsenal return to the summit with a fifth Premier League win in a row? All those questions and more to be answered later, but first, a look at the team news...
Subs: Bayindir, Amass, Kambwala, Eriksen, Collyer, Forson, Antony, Wheatley, Ogunneye
Subs: Ramsdale, Zinchenko, Kiwior, Jorginho, Vieira, Smith Rowe, Martinelli, Jesus, Nketiah
Amrabat, McTominay and Kobbie Mainoo will seemingly offer more protection in a midfield trident. Ten Hag playing it safe or just no real alternatives? A bit of both most likely.
On current form, no surprise at all, although Casemiro does serve as his country's captain...
Takehiro Tomiyasu and Bukayo Saka have both shaken off knocks to start.
No Jurrien Timber, though; he has travelled with the squad but is still being held back. The Gunners bench looks heavily stacked either way.
As if the Old Trafford faithful needed another reason to feel pessimistic about today's game.
They will return to top spot with a win and ensure that the title race goes down to the wire, but any other result and Manchester City can clinch the crown at Tottenham Hotspur on Tuesday.
Something tells me that will not be happening.
Confirmed that Amrabat's inclusion was to try to stifle Arsenal in possession in the middle of the park, while Diallo "deserves" his chance on the right. Think few could argue with him there.
Not even the Invincibles managed 27, but the Gunners can write club history today.
Not many would put it past them to smash that record against a Man United side with a penchant for conceding shot after shot.
Martin Odegaard, Declan Rice and Gabriel Jesus - also omitted from the Brazil Copa America squad - scored on that sunny North London day.
Paul Tierney was the referee on that day and is the man in the middle here as well.
Arsenal have not done the double over your team for 17 years, last achieving that feat in the 2006-07 season, where Emmanuel Adebayor struck at Old Trafford.
Do not mention his name in the red half of North London these days, though.
With Golden Glove winner David Raya in between the sticks, it is fair to say Arsenal are - literally - still in safe hands.
However, Man United have scored in all of their top-flight home games since the turn of the year.
The women's team are on the cusp of doing just that - they are 4-0 up against Tottenham Hotspur in today's Wembley final with fewer than 10 minutes to go.
How about a bit of trivia while we wait? Arsenal's William Saliba is just one of two outfield players to play every minute in the Premier League this season, can you guess the other?
Hint, he is also a centre-back.
I reckon Man United will still find the net - even with Fernandes and Rashford out - but Arsenal's fire will be too hot to handle. 3-1 to the Gunners... again.
Here they come! Odegaard and McTominay sporting the armbands and leading their teams out.
Or will Arsenal soon be mourning their title fantasy?
Kai Havertz tries to flick a ball to the back stick, but Diallo pokes the ball behind for a corner.
Encouraging stuff from the visitors, though.
McTominay robs Partey of possession just outside the Arsenal box but Hojlund skies his chance. A big chance at that.
Still, see below - big chance.
Diallo slips in Garnacho, but Gabriel's leg deflects the ball over for a corner.
Tell you what, Diallo looks really up for this.
The Englishman slips and sells Raya short with a backpass, but the Spaniard gets there just before McTominay or Hojlund can nip in.
The first 120 seconds or so were ominous, but they are now looking settled in possession and capable of troubling the visitors out wide.
Arsenal clear, back to square one.
However, the Portuguese takes up that familiar full-back's central position to let fly from 20 yards, but his shot is high and not handsome.
Trossard is the next to swing a cross in from the left, which misses everyone.
Rice is slipped in in the United box, but Casemiro stands up to him twice and prevails twice. Improvement from the Brazilian.
From hero to villain, Casemiro plays Kai Havertz onside from Ben White's ball over the top after Man United lose possession straight from a goal kick.
The German advances towards the byline and cuts back for the arriving Trossard, who catches Wan-Bissaka napping and taps home from a yard out.
Either way, Gooners will still need to support Spurs for a couple of hours on Tuesday.
"That is a huge goal for Arsenal, who may have been beginning to worry about their Old Trafford hoodoo following a good start from Man United.
"Arteta's side showed brilliant game management to take the sting out of that start by spending a spell in unhurried possession just before that goal, and then they upped the tempo at the opportune moment.
"It is dreadful defending from Casemiro, and Wan-Bissaka was caught flat-footed too, and all of a sudden Man United's positive opening 20 minutes counts for nothing."
Ben White then has a go from a tight angle, but that one is not troubling Onana.
The £105m man has not set the world alight so far, but Arsenal are in the lead, and that is really all that counts.
Casemiro's speculative drive was headed away by Gabriel, though.
McTominay's attempt from range now trickles harmlessly wide.
Garnacho cuts inside and lets fly, but Tomiyasu is there, and White eventually chests back to Raya.
In fact, he steps on the foot of Partey, who was already on the floor.
Partey did have a panicked look on his face as the Ivorian fell to the ground, but no penalty given.
Tierney not allowing the free kick to be taken quickly, though.
Alejandro Garnacho charges forward into the left-hand side of the box but is eventually swarmed by yellow shirts, and Arsenal survive.
He accepts the invitation and tries to pull a cross back for a teammate, but Raya is down low quickly to beat away the chance. Promising signs at the end of the half!
Saliba just landed awkwardly after a nudge from Hojlund, but the Frenchman is quickly back up again and OK to carry on.
He tries to find Hojlund, but Saliba manages the situation well before Mainoo puts in a cross, which Raya claims.
Man United started brightly and had a good structure about them, but a dilly-dallying Casemiro allowed Havertz and Trossard to link up for the opener.
Diallo has been especially bright for the hosts, but Raya has been relatively untroubled in between the posts.
As things stand, Arteta's men heading back to the summit!
All of their side's hard work inside the opening 20 minutes undone by one defensive lapse.
Meanwhile, Arsenal have been unyielding at the back, and are yet to face a shot on target.
This poor bloke currently being torn to shreds by the Sky Sports panel right now.
In fairness, had he made a two-second sprint to play Havertz offside for Trossard's opener, Man United may have headed down the tunnel with their clean sheet intact, or better.
"Advantage Arsenal at half time, but their fans won't be able to breathe too easily unless they get a second goal.
"Man United have been decent on the whole in that first half, but they haven't really looked like scoring; Amad and Garnacho have shown glimpses of being able to breach that solid Arsenal backline, albeit only in fleeting moments so far.
"The next goal, if there is one, will be crucial in this game. As it stands, it is Casemiro's lazy defending which has been the main difference between two teams in an otherwise even match on the whole."
General consensus is that the Ghanaian's challenge on Diallo was borderline, but not spot-kick worthy.
Might Arteta consider bringing Jorginho on for the second half?
No changes from either side.
Once more, though, Casemiro gets the better of Rice on the left. The Brazilian is at least winning that battle so far.
Saliba and Gabriel bail him out, but that has lifted the home fans a bit.
Been the hosts' most encouraging player so far this afternoon.
You would suspect there will be a few more to come if he carries on like this.
Trossard tries to play provider for Havertz, but not even the 6ft 4in German can reach his overhit cross.
Sums up Man United's Premier League season, really.
Arsenal get some joy in and around the Man United box, but the Red Devils right-back throws his body in the way of Rice's low attempt.
A corner comes in from Saka, which Saliba flicks on and over at the near post.
Garnacho is advancing at lightning speed into the Arsenal box, but the Frenchman stands up to him and nonchalantly puts a foot in to stop the attack in its tracks.
Arteta's management of him amid his three loan spells was questioned, but not any more.
Just the 13 years separating those two at either end of the experience scale.
He has so much time to open up his body and pick his spot, but his strike is well wide. Had to do better there.
Another Red Devils surge sees Garnacho race away down the left, but he loses his footing, and White can usher the ball out for a goal kick.
This time, though, Saka wins his duel with Garnacho, but Man United straight back on the ball.
The Gunners captain cuts inside onto his left boot, but his 20-yard shot is too central to worry Onana.
A useful option against a jaded Man United backline.
He tries his luck, but Raya is behind it.
Antony is on.
Arsenal play it short, Amrabat outmuscles Saka and Saka fouls Amrabat.
Booking for the 22-year-old.
Who am I to question Nicolas Jover's wisdom, though?
Amrabat has a bit of time to pick his spot, but he slips and Rice blocks.
What a game the Frenchman has had.
McTominay feeds the tricky teenager out on the left, but he gets no change out of White this time and cannot find the postage stamp from a tight angle.
Martinelli has the beating of Wan-Bissaka as he cuts inside, but he waits an age to get his shot away.
Onana has to acrobatically tip it over the top, though.
End-to-end as we enter the last 10!
Raya punches the corner clear and Martinelli is one-on-one with Wan-Bissaka, but the United man comes out on top.
Jesus takes his place.
Onana firstly saves from his own man as Wan-Bissaka heads on a corner, before pushing a Rice drive behind, and the resulting set-piece is cleared.
Arsenal going for the jugular!
Real lack of quality from the hosts in the final third.
More importantly, can Arsenal weather a late United storm? Ten Hag about to make a triple change it seems.
Amrabat, Wan-Bissaka and Rasmus Hojlund - who has been quiet - are withdrawn.
Wheatley is immediately caught offside from a long ball over the top.
Onana makes a meal out of dealing with Martinelli at his feet, but thankfully for him, Eriksen is there to hack clear.
Garnacho stays down holding his face after a clash with Jesus, but nothing doing there.
This time, Dalot's delivery from the right is straight at the Spaniard.
Garnacho sends an effort wide as the rain pelters down.
Might that be that?
It was not pretty, but who cares about pretty?
Leandro Trossard's goal is the difference, and Arsenal return to the top of the Premier League table for at least another 48 hours. The race for glory WILL go down to the final day!
As for Man United, their already-slim European hopes fade that little bit more, but there is no raining on Arsenal parade in the torrid Mancunian conditions.
Now, Gooners, time to learn some Tottenham chants!
