Their worst league campaign for 25 years ended on a high note, securing Mikel Arteta his first trophy as a head coach and ensuring the Gunners will be playing Europa League football next season.
After the pain of the 2019/20 Premier League season, being able to head into a break with a title in the bag was, understandably, reason for the players to go a bit crazy. Celebrations likely went late into the night, as the squad revelled in overcoming Frank Lampard's side.
Here's how some of the stars celebrated.
Only being in the job since December, the Spaniard has exceeded expectations in his debut (half) season as a top flight manager. Six years on from lifting the trophy with Arsenal as captain, Arteta clearly enjoyed the moment.
He may have deflected when asked about whether he will be staying at the club, but even with speculation rife about his future, Pierre-Emerick Aubameyang's two-goal cameo to secure the Gunners the trophy quickly masked over any uncertainty.
For now, it was all about celebrating his seventh trophy as a player and his first in Arsenal colours. He didn't hold back, with new boy William Saliba rinsed in some of the videos.

On the team bus after the game the party continued to escalate, with music and Prosecco (presumably champagne is not in the budget) in abundance.
There was even a fair bit of banter flying around from the younger players claiming Aubameyang is, indeed, the G.O.A.T.
All the talk ahead of kick off was around David Luiz and whatever involvement he may have. Mostly, it was about him potentially dropping a few clangers and handing the game on a plate to Chelsea.
Fortunately for him and Arsenal, he was solid and error-free.
An avid user on social media, his comical outlook on life filtered through into the celebrations, although his focus this time was on being humble and thanking the other members of the squad. Even the ones who don't play. How lovely.
Nicolas Pepe, Hector Bellerin, Alexandre Lacazette & the Rest
It wasn't just the two senior players basking in their success, though. The rest of the squad were equally overjoyed at their triumph, with wild celebrations matching those of their fellow teammates.
Alexandre Lacazette in particular was keen to poke fun at one certain member of the opposing team, Olivier Giroud. Infamous for thanking Arsenal after winning the Europa League final for Chelsea against his former side last year, there was no love lost.
Fashion icon Hector Bellerin was keen to show off his medal in the only way he knows how. Wearing it as an earring, of course.
Nicolas Pepe caught some of the squad dancing the night away.
There was one emotional moment too, involving Emiliano Martinez.
Having joined the club as a teenager ten years ago with a promise to his parents that he'd become a success, the emotion of the achievement clearly got to him when he began to well up during his post-match interview.
A video call with the family back in Argentina followed and someone, somewhere, started chopping onions.
Oh, yeah, and it's kind of hard to ignore the fact that Aubameyang dropped the trophy before the first team lift.
That moment they've all been waiting for, turned into a moment of hilarity in one fell swoop. Comedy gold.
