Pierre-Emerick Aubameyang's first Premier League hat-trick guided Arsenal to a 4-2 victory over a leaky Leeds at the Emirates despite the visitors' late rally
Arsenal were 3-0 up at half-time for the first time in the Premier League since February 2018 as Leeds crumbled, and it was Aubameyang, who has now scored more goals in his last four Premier League appearances (5) than he had in his previous 16, benefiting most
First, Aubameyang's clever, flash finish into the near post from 15 yards (13) put Arsenal ahead, before the Gabon striker doubled his and the Gunners' tally with a penalty after goalkeeper Illan Meslier mistake, dwelling too long on the ball before fouling Bukayo Saka (41)
Hector Bellerin's first goal of the season made it 3-0 on the stroke of half-time, again finishing at the near post following superb Arsenal interplay in the box (45), and Aubameyang got his hat-trick after the break with a far-post header from Emile Smith Rowe's cross-shot (47)
As ever with Leeds, there was entertainment at both ends as Marcelo Bielsa's side caused a scare, halving the deficit through Pascal Struijk's bullet header (58) and sub Helder Costa's close-range finish (69), but Arsenal saw the game out
The result means Arsenal leapfrog Leeds into 10th, though Leeds are two points behind with a game in hand
Few at the start of the season would have predicted this would be a mid-table clash in mid-February, or that Leeds would be a point ahead of Arsenal with a game in hand, but the Gunners took a step to readdressing that thanks to a fine first-half show
Leeds' style means it's either "feast or famine" for Marcelo Bielsa's side this season, said Alan Smith on Sky Sports commentary, and this was certainly the latter as Arsenal led 3-0 at the break
Playing through the middle, Aubameyang put the hosts ahead with a trademark striker's finish, bursting into the box with a few stepovers, using defenders Liam Cooper and Luke Ayling as a wall as he struck through them both and low into the near post from 15 yards
Aubameyang should have doubled Arsenal's lead as David Luiz's cut-back from the byline found him in space, but his goalbound effort was brilliantly blocked by Ayling
Arsenal thought they had a penalty as Saka went down in the box having brushed past Cooper, but VAR intervened, and after Stuart Attwell went to the pitchside monitor, the decision was overturned
But just moments later Meslier gave away a stonewall penalty, dwelling on the ball from a pass-back, allowing the livewire Saka to nip in, before fouling him just inside the box
 Aubameyang dispatched, sending Meslier the wrong way for his 200th goal in Europe's top five leagues
Arsenal toyed with Leeds and got another just before the break, as intricate build-up play from Saka, Smith Rowe and finally Dani Ceballos in the box allowed Bellerin space to shoot from 10 yards, and his near post shot went through Meslier, who should have done better
 It was "five-a-side" football from Arsenal, said Smith on commentary
Aubemeyang completed his hat-trick just two minutes after the break as Smith Rowe, entering the box from the left, looked to aim an effort for the far corner, but instead the ball fell perfectly for his team-mates head at the far post to head home
Leeds were given a lifeline with half an hour remaining as Struijk rose above Luiz from a Raphinha corner, powering his header home, before sub Costa latched onto sub Tyler Roberts' centre at the near post, poking past Leno to bring Leeds within two
Patrick Bamford wanted a penalty after being squeezed out in the box by Cedric and Gabriel, while at the other end Aubameyang struck the bar with a snapshot from 12 yards
Arsenal managed the closing stages well and saw out the victory, their first in three Premier League games, leaving them just six points behind champions Liverpool in fourth, and five points off the top six
Mikel Arteta will now be looking on a surge for the European spots, while Bielsa's Leeds continue to entertain, with 82 goals scored in their 23 Premier League fixtures this season
Arsenal boss : "[Aubameyang] has been training really good, he wants to get back, he wants to help the team and I could see this week, I had a feeling to put him as the No 9 today and he has done the job
"The amount of chances we created and the type of goals we scored today really pleased me
 The attacking patterns we had today, the confidence that the team had against a team that is constantly pressing you to be comfortable to get out of this situation
 Overall, a lot of positives
"Leeds boss  : "When we were building from the back, we didn't manage to take the ball from our half to their half, there were no surprises for either of the two managers, they knew how we were going to press and they resolved this
"And we knew how they were going to press us and we didn't manage to resolve this
 And in the second half the opposite happened
 In the first half we didn't defend well
 And we didn't defend well because the ball went from back to front too comfortably, too easily for Arsenal
