Manchester City blew the Premier League title race wide open by edging an epic game 2-1 at the Etihad Stadium to move within three points of long-time leaders Arsenal - and hold a game advantage with which to close that gap.
City, who have only been top for a total of six days all season, will have the chance to overtake Arsenal by beating next-to-last Burnley on Wednesday. The remainder of the campaign would then be decided by a tense five-game run-in, with Mikel Arteta's side needing to balance the demands of Europe simultaneously.
The conclusion of this fascinating two-way tussle, to mirror events in Manchester, remains on a tantalising knife-edge.
Arsenal were undoubtedly out to answer critics of their title credentials. Their last three domestic outings - against Man City in the EFL Cup final, Southampton in the FA Cup, and Bournemouth in the Premier League - had all ended disastrously.
Arteta got it wrong against City at Wembley last month. His selection at the Etihad, though, felt much more balanced, the strongest blend Arsenal had available without Bukayo Saka. And they pressed high like they knew it was the case, risking being played over in favour of the spoils if the ball turned over. Caution to the wind.
Rayan Cherki's opener arrived despite Arsenal's aggressive start, as the Frenchman danced past Gabriel like he was not there, the ball sticking to his foot like velcro, and poked into the far corner of David Raya's goal. A magician at work.
But 108 seconds later the visitors were level, deservedly so. Kai Havertz had hounded Gianluigi Donnarumma from the first whistle and then made good on his threat when charging at the Man City goalkeeper and forcing an almighty error. It was a first half played at intensity, one that bated a grandstand finish. The second 45 did it poetic justice.
It started with Haaland hitting the post at one end, before Havertz was denied in a 1v1 with Donnarumma and Eberechi Eze also cracked the woodwork. The visitors were on top, looking creatively more likely to unearth a precious winner.
But 'stay humble' Haaland had other ideas. He struck the decider midway through the second period, finishing off a devastating move that started with Donnarumma and ended with the No 9 sweeping beyond Raya after a driving run from the excellent Nico O'Reilly.
Gabriel, and Arsenal, were outwitted again. The Gunners defender headed against the foot of the post and could - perhaps should - have seen red before the afternoon was out after confronting Haaland with an unwise head gesture - the emotions of an unravelling title tilt seemingly spilling over. Havertz was guilty of a tremendous late miss, too.
Are Arsenal really throwing away their best claim at league champions for over 20 years?

Arsenal boss Mikel Arteta:
"Very upset with the result obviously. We came here to win. The message was clear. We believed we could win it. We proved that we are there, but the reality was in the two boxes. That was the difference.
"I believe [we can win the title] because I see them every day, I know the level we have. They [the players] are now more convinced, they were talking about it in the dressing room. Everything is still to play for. We know how much we want it and we're going to go again.
"We will learn from what happened today, and be better. The margins, we hit the post, there is an element of luck, of timing, of execution. They didn't go our way. We have to recognise that.
"Obviously we are disappointed, in the manner that it happened. I said to the players 'ok we lost an opportunity', but we have the biggest one in the next five games so let's do it."
Man City head coach Pep Guardiola:
"It's a good advert for the Premier League. They don't allow you go through your process, they are so aggressive, good in the duels, one of the most competitive teams I ever faced in my career in terms duels, 1v1, long balls.
"We had momentum, they had momentum. We had chances, they had chances. In the end, it's the fine margins.
"Two teams with really top managers. And top, top players from both sides.
"But the reality is just one thing: they are top of the league. One ahead on goal difference. We have to enjoy it, celebrate it, take the good things. But don't lose the focus. In three days we go to Burnley."
