Even when the writing was on the wall at the Emirates Stadium, the travelling Bodo/Glimt supporters were in full voice throughout the evening, but their unwavering support could not prevent their side from going down 3-0 to the rampant Premier League leaders.
Eddie Nketiah's finish, Rob Holding's header and Fabio Vieira's first European goal for Arsenal condemned Bodo/Glimt to a humbling defeat in North London, and their knockout fate is now out of their own hands with half of their games gone.
The Norwegian champions find themselves level on points with PSV Eindhoven in third place in the Group A standings - both picking up four apiece so far - but the Dutch outfit still have a game in hand and will expect to run out comfortable winners over FC Zurich later this week.
Knutsen's side could still upset the apple cart in the Europa League but are firmly at risk of dropping down to the Europa Conference League for a second consecutive season, and they warmed up for this game in ideal fashion with a 4-1 Eliteserien victory over Sandefjord on Sunday.
However, that success marked Bodo/Glimt's eighth game in a row without a clean sheet in any tournament, but they have countered such frailties with a 16-game scoring streak on home soil since May, and such proficiency must be at its peak if they are to shock the Gunners.
Incredibly, Bodo/Glimt have won each of their last 14 home games in European competition and could now equal a 15-match victorious run from Barcelona, which ended in 2017, but that record is certainly at risk of coming to an end against an Arsenal side who are daring to dream.
Critics of Arsenal's brilliant start to the season were quick to point out that the Gunners had not yet faced any real tests to their Premier League supremacy, but such talk has quietened down with back-to-back wins over Tottenham Hotspur and Liverpool, even if the latter success was full of controversy.
Two goals from Bukayo Saka and a quickfire opener from Gabriel Martinelli ultimately saw Arsenal end their recent hoodoo against Jurgen Klopp's Liverpool, and Mikel Arteta's youthful crop are still holding off Manchester City at the top of the Premier League standings, but there is still just one point in it.
Talk of a Premier League title challenge is still very premature for Arsenal, whose goal of going all the way in the Europa League is still well and truly alive after their previous failed ventures, and they could find themselves five points clear at the top of Group A if results go their way here.
With their winning streak in all competitions now standing at five matches, Arsenal travel to Norway aiming to score away from home in the Europa League for the 17th game running, and several players will aim to stake their claims for more prominent roles in the Gunners' domestic push.
Bodo/Glimt found themselves 1-0 down at half time against Sandefjord before Knutsen relented and introduced Runar Espejord and Ulrik Saltnes, both of whom ought to come back into the first XI this week.
Joel Mvuka and Ola Solbakken will continue their battle for supremacy on the right-hand side of the attack, and the fresh legs of the former may be preferred from the first whistle at the Aspmyra Stadion.
As for Arsenal, Mohamed Elneny (hamstring) and Emile Smith Rowe (groin) are still watching on from the sidelines, and Arteta will be loath to risk Oleksandr Zinchenko if he has not fully recovered from a muscular problem. Gabriel Jesus, meanwhile, has been left at home to rest.
Changes will be aplenty for the North London club, who should recall the likes of last week's goalscorers Holding, Vieira and Nketiah to the starting lineup, as well as Albert Sambi Lokonga, Marquinhos and Kieran Tierney.
Arteta's decision to start Takehiro Tomiyasu at left-back against Liverpool paid dividends, and the Japan international could now line up alongside Holding in the back four, allowing Gabriel Magalhaes a much-needed reprieve.
Bodo/Glimt possible starting lineup:
Haikin; Sampsted, Moe, Lode, Wembangomo; Vetlesen, Berg, Saltnes; Mvuka, Espejord, Pellegrino
Arsenal possible starting lineup:
Turner; Cedric, Holding, Tomiyasu, Tierney; Xhaka, Lokonga; Marquinhos, Vieira, Nelson; Nketiah
We say: Bodo/Glimt 1-2 Arsenal
With the roar of the ever-enthusiastic home crowd behind them, a Bodo/Glimt side renowned for their European exploits on home soil can expect to give Arsenal a better run for their money than their humbling at the Emirates.
Arteta is sure to field another youthful and second-string XI this week, and while the reverse tie will not be the cakewalk it was last week, Arsenal can call upon the cavalry if required and make it three wins from three in Europe.
