Mikel Arteta's side celebrated their first league title in 22 years at Selhurst Park on Sunday, staying at the ground for nearly two hours after the final whistle before the PA system eventually cleared them out. The celebrations continued into the night at Bacchanalia, a private restaurant in Mayfair, where the squad gathered with family and friends.
Singer Louis Dunford performed Arsenal's club anthem. Declan Rice danced with the Premier League trophy and, to the delight of those present, rapped along to Vanilla Ice.
Now the party pauses. Arsenal face Paris Saint-Germain in the Champions League final at the Puskás Aréna on Saturday, and Arteta wants that energy transferred directly into preparations.
"We need that energy to flow, and going against that, will be a big mistake," he said. "We talked already about what we have to do in Budapest, how we're going to use all the incredible energy that we're all carrying towards that final."
It would be Arsenal's second European crown and only their second appearance in a Champions League final, having lost to Barcelona 2-1 in Paris in 2006. PSG arrive as holders, having beaten Inter Milan to lift the trophy last season, and they eliminated Arsenal in the semi-finals at the same stage of that campaign.
Rice acknowledged the weight of what is at stake.
"From the other night, it felt like a relief came off us," he said. "And we have now got a confidence about us, so bring that game on. We know what is at stake. Not many people get to say they have played in a Champions League final, so we have got to embrace it."
Club co-owner Josh Kroenke, who has become a regular presence at the club this season, said the title win had visibly shifted something within the group.
"I am very excited for Mikel and our group to play," he said. "I can feel a different spirit out of the group. And I am excited to see what this group of coaches and players can do just by being free."
The freedom Arteta described is real. For years, Arsenal carried the burden of near-misses and second places. That weight is gone.
A year ago at Anfield, a banner mocked Arteta with the image of a bride who never quite made it to the altar. The Spaniard was moved to tears on Sunday as he held his wife Lorena and watched his players lift the title.
If Arsenal win in Budapest, the trophy parade through north London next Sunday carries a different meaning entirely. Arteta knows it.
"We are the champions and that brings a lot of confidence and a different kind of presence and energy to it," he said. "My job now, and everybody at the club, is going to be to live those standards and achieve more and more — because we are capable of winning."
