Mikel Arteta - who has been at the club for nearly six and a half years - has built a combative team that have won the title with resilience, willpower, an incredible defence, and set-piece prowess. It hasn't always been pretty, but ultimately, that doesn't matter one bit.
There were plenty of bumps in the road as Arsenal navigated choppy waters, with some victories meaning significantly more than others.
So, which results were most key on their path to the Premier League title?
Manchester United 0-1 Arsenal (Matchday 1)
All eyes were on Old Trafford as Manchester United hosted Arsenal in both sides' opening game of the season, and Arsenal truly gave a sign of what was to come for the rest of the campaign.
The only goal of the game came early on from one of the Gunners' most prolific sources - a corner. Riccardo Calafiori was the man who headed home from close range after Altay Bayindir flapped under pressure.
However, United dominated most of the game, having 22 shots to Arsenal's nine. Yet Arteta's side always seemed confident in seeing out the game, with David Raya magnificent in goal and the defenders resolute - as they have been all season.
The prototype Arsenal performance and result. They have won eight games 1-0 in the Premier League this season; only in 1998/99 did they do so more (9). They have also scored a set-piece in 19 of their 37 league games, excluding penalties.
Start as you mean to go on.
Newcastle 1-2 Arsenal (Matchday 6)
After a 1-1 draw at home to Manchester City, which saw Arteta come under pressure for being too safe and conservative with his team lineup, Arsenal faced an incredibly tricky trip to Newcastle, a place where they have often struggled and come up short.
Arteta had been starting Declan Rice, Mikel Merino and Martin Zubimendi in a pretty robust midfield that lacked creativity, but against Newcastle, he brought £60 million signing Eberechi Eze into the side, looking to add a bit of X-factor.
And Arsenal delivered a fantastic performance, playing some attacking, free-flowing football despite going 1-0 down after half an hour following a Nick Woltemade goal.
They spent the whole of the second half knocking on the door, having 73% possession and 11 shots to Newcastle's four.
Arsenal scored two late goals - from two more set-pieces. The first came from a Rice cross, as substitute Merino headed home cleverly. Centre back Gabriel Magalhaes then towered above everyone else in the 96th minute, crashing home another header to give Arsenal a brilliant win at St James' Park.
It felt like their first true statement victory of the season and temporarily quietened some of the noise.
Arsenal 4-1 Aston Villa (Matchday 19)
A few weeks after suffering a brutal last-gasp loss at Aston Villa, Arsenal were heading into the new year top of the table, with a high-flying Villa their opponents yet again, this time at the Emirates Stadium.
It was a rare occasion in which Arsenal were without midfield powerhouse Rice, so there was some concern about how they would cope against a team in such red-hot form.
Following a tense first half, the Gunners turned it on in the second as Amadou Onana was taken off with an injury. Gabriel scored from yet another corner, before goals from Zubimendi, Leandro Trossard and Gabriel Jesus ripped apart the Villans in a scintillating second-half performance.
Leeds 0-4 Arsenal (Matchday 24)
Coming off the back of draws against Liverpool and Nottingham Forest, and a home defeat to Manchester United, the pressure was beginning to really ramp up on Arsenal. The 'bottlers' tag was being thrown around, with many anticipating that they would start to crumble.
A trip to Elland Road against a resurgent Leeds United side looked like an extremely tough fixture for a team that were getting wobbly. Yet it proved anything but.
Zubimendi, Noni Madueke, Viktor Gyokeres and Jesus all scored in a thumping victory, stabilising Arsenal and getting them back on track. It was also Madueke's first Premier League goal for Arsenal, with him scoring directly from a corner (of course).
Tottenham 1-4 Arsenal (Matchday 27)
Heading into a crunch North London derby at the Tottenham Hotspur Stadium, Spurs were smelling blood. Arsenal had just thrown away a two-goal lead to draw against bottom-of-the-table Wolves, and Manchester City were applying real pressure on the Gunners.
But led by Eze, who had scored a hat-trick in the reverse fixture at the Emirates, the Gunners ran riot against their arch-rivals. The England international bagged a brace at the home of the side he was on the verge of joining in the summer, while under-pressure striker Gyokeres was also at the double.
A huge morale-booster and momentum-builder for Arsenal, and they had truly taken bragging rights. The aggregate score against Spurs this season was 8-2.
Arsenal 2-0 Everton (Matchday 30)
Manchester City had just dropped points to Nottingham Forest, and Arsenal had breathing space at the top of the table. It was imperative that they kept their foot on the gas. An Everton team, who have been so strong away from home this season, visited the Emirates, and it had the potential to be a real banana skin fixture.
Arsenal played well for large portions of the game, but were unable to find a way through a solid Everton defence. Enter 16-year-old Max Dowman.
A special talent who is so incredibly highly-regarded by Arteta and those at Arsenal, the Spaniard showed full faith in the youngster to try and make an impact.
Dowman did just that, adding some more impetus to Arsenal in the final third. With two minutes to go of normal time, he put in a cross that goalkeeper Jordan Pickford missed, allowing Gyokeres to tap home.
In added time, Dowman completed the victory with a fairytale moment, carrying the ball from inside his own half and tapping into an empty net with Pickford up for a corner. He became the youngest Premier League goalscorer ever in the process (16 years and 73 days). Another remarkable chapter in a remarkable season for the Gunners.
Arsenal 1-0 Newcastle (Matchday 34)
Following defeat to Manchester City at the Etihad, Arsenal went into the game against Newcastle in second place for the first time in a long while. City were ahead on goal difference, and suddenly, the psychology had shifted.
Arsenal needed to prove that they weren't going to fade away and were willing to take some punches, and simply had no option but to win against Newcastle.
The only goal of the game came from Eze in the ninth minute, with the 27-year-old scoring an absolute pearler from long range, after a very cleverly worked short corner.
It was a nervy, nervy game for Arsenal and their fans, and it was far from awe-inspiring. But it didn't have to be. They showed their resilience and fighting attitude, which they had all season, keeping another clean sheet and winning 1-0 once more.
All that mattered was three points, climbing back onto the horse.
West Ham 0-1 Arsenal (Matchday 36)
Ahead of the game, this clash felt like a contest of seismic proportions at both ends of the table. Arsenal had regained control of the title race, and a trip to their London rivals, West Ham, who were battling relegation, had so much at stake.
The game was on a knife-edge, and as the minutes ticked by, you could feel the pressure ramping up inside the London Stadium.
Deep into the match, West Ham midfielder Matheus Fernandes had a huge chance to give his side the lead, but Raya made himself big to make a terrific save and prevent what looked like a clear goal.
Then, in the 83rd minute, Arsenal took the lead thanks to Trossard, who slotted home calmly after some good work from Martin Odegaard.
There was more drama, though, as West Ham thought they equalised in the dying embers of the game when Callum Wilson thumped home. However, the goal was ruled out after a long and tense VAR check for a foul on Raya - probably the most consequential use of VAR in Premier League history.
1-0 to the Arsenal, yet again. Perhaps this was truly the decisive moment in the title race.
