Reiss Nelson was the hero for Arsenal as his 97th-minute winner sealed an astonishing Gunners comeback from 2-0 down to a 3-2 victory over Bournemouth
A bizarre encounter at a raucous Emirates Stadium began with the Cherries taking the lead after just nine seconds, as a well-worked kick-off routine was finished by Philip Billing at the back post
Mikel Arteta's side dominated the possession and chances against the relegation-threatened side, holding 80 per cent of the ball and mustered 30 shots on goal overall - but fell further behind to Marco Senesi's header from a corner
But Arsenal's young side were not to be disheartened as they levelled the game with two goals in seven minutes after the hour mark
 Both goals came from unlikely sources as Partey tapped home at the back post from Emile Smith Rowe's header, before White finished Nelson's cross
And as Arsenal huffed and puffed for a winner, Nelson curled home with the last kick of the game to spark bedlam at the Emirates, with the Gunners' five-point lead at the top of the table maintained
Fans were still filtering into the stands when Bournemouth took a surprise lead in even more stunning circumstances
The Cherries players put five players on the left of the halfway line at the kick-off but played the ball right to Dango Ouattara, who crossed for an unmarked Billing to tap home past Aaron Ramsdale
The Emirates were stunned but the home crowd roared their team towards encouragement
 It nearly led to a quick equaliser as Neto got down well to save Martin Odegaard's shot from the edge the box, the Cherries goalkeeper also quick to deny Bukayo Saka at the rebound
The same Arsenal duo tested the Bournemouth goalkeeper again - but despite the hosts having around 85% possession, the Cherries created the next big chance of the game
Dominic Solanke's break saw him play Billing in behind the defence, played onside by the retreating Leandro Trossard who was carrying an injury
Billing squared to Solanke and Ouattara in the penalty area, who were both waiting for a tap-in but Ramsdale denied the latter with a superb sprawling save
Trossard limped off injured with Emile Smith Rowe replacing him off the bench
 That dampened Arsenal's momentum slightly in terms of attacking influence, despite seeing two VAR checks on a Chris Mepham handball and a challenge on Takehiro Tomiyasu go against their way
Arsenal continued their dominance after the break but what nobody saw coming was a Bournemouth second
 Partey fell asleep at a corner and it allowed Senesi to run across him and head past Ramsdale
Jack Stephens nearly gave Arsenal a way back into the game as his wild slice ended up in the back of the net but the resulting corner saw the Gunners pull one back
Neto punched an Arsenal corner clear and Smith Rowe headed onto Partey at the back post, who tucked home in a moment of redemption for the midfielder
The Emirates noise levels rose again and Bournemouth could only last seven minutes before succumbing to another goal
 Arteta brought on Reiss Nelson for Smith Rowe and the substitute's cross was met by White at the back post
The England defender's first-time finish was clawed out by Neto from behind the line, but goal line technology validated the effort
Arsenal went to complete the comeback as Martinelli broke clear behind the Bournemouth backline, but blazed over as he entered the box
 Vieira saw a long-range shot end up in a similar outcome while the Gunners had handball appeals on Senesi and Billing waved away by VAR
Arsenal thought the chance had gone when Oleksandr Zinchenko's deflected effort bounced wide
 But Nelson stole the show at the end by finding that same corner
Mikel Arteta walked into his post-match press conference and the first question was whether he believes in fate
 "Yes, I do," was his response
 You can certainly see why
Because it was all going haywire for Arsenal
 Two goals down at home to Bournemouth, their first three centre-forwards injured and a slightly makeshift front four in its place
Gabriel Martinelli was playing up top, in a role he has never been in this season
 A raw Emile Smith Rowe came on having played barely an hour of league football all term
 Bukayo Saka was being doubled up against
 Fabio Vieira was making just his second start of the campaign but was tasked with dictating the play
 Alternatives? There were barely any, just one Reiss Nelson who had played one league minute since October
But the front five of Saka, 21, Martinelli, 21, Vieira, 22, Smith Rowe, 22, Nelson, 23, and captain Martin Odegaard - the senior of the group at 24 - pulled through
 They toiled, toiled and toiled to the point where Bournemouth, also facing the wrath of the Emirates crowd, couldn't hold on any longer
Arsenal turned it round
 In the space of one Nelson swish the whole dynamic changed
 It's what they've done all season
 This was the fifth time in the Premier League this season where they've gone behind and gone on to win
"It was probably the loudest and most-emotional moment we have lived together," he said
 "The journey that we've been on together and how the supporters and team are together, adding the important moment we had today, it was very special
"Everybody is probably overwhelmed a little bit
 It was madness from the first second of the game with a routine we knew they could do and we defend so poorly
"Then we just had to climb a mountain with 10 players behind the ball
 We tried every single way, we didn't score the goal and suddenly, we are 2-0 down with a set play again
"After that, we don't lose the shape, don't lose the discipline and start to do all the simple things right and try to score the first goal
 We showed maturity and resilience to do that
 Once we did that, the atmosphere changed and the energy
"Once we scored the second, it was 'OK, let's throw the toys out and go for it'
 The subs made a huge impact today, I'm so happy for Reiss after the difficult months he's had
"I think the team and individuals showed they had a different level of willingness to win, determination and initiative, because when the game gets ugly, there is a moment where you can lose momentum
 You can start to hide and to navigate through the game
"But the players didn't do that
 They wanted the game, every time with the ball, they took risks, took initiative and kept trying until we broke them down
 It was great to see that from the team
"[When the winner went in] you lose sight of where you are
 I started to run and I didn't really know where I was running to! But just looking in the faces of everybody, the staff, the players, our supporters with that joy in their eyes, it's great to live
"It was an extraordinary day, a beautiful experience at the end
 Very dramatic, but worth living because it was a great end to it
""It's just another game and another three points
 To win three in a week in this league is extremely difficult
 We've done it and you have to win games in different ways
 Hopefully that will give us more belief
"We want to stay there [at the top of the table] but obviously it's going to take a lot of effort
 There's still a lot of games to play and the Premier League, unfortunately every game is like that, but that's the beauty of it
""I thought we gave it a real good go against the best team in the country
