Arsenal have been a fixture in Europe’s top competition for most of the past 30 years without ever getting their hands on it. They have reached two finals, lost both, and spent long stretches in between going out at the same stage to the same kind of opponent. The 2026-27 league phase opens on 8 September, with Napoli vs Arsenal taking place the day after, and the question that has followed the club around Europe for two decades has not changed much.
Paris 2006: The Closest They Came Under Wenger
Arsene Wenger took Arsenal into the Champions League in 19 consecutive seasons, and 2005-06 was the campaign that should have ended the wait. His side went 995 minutes without conceding a goal, a competition record, and knocked out Real Madrid, Juventus and Villarreal on the way to the final in Paris.
Then Jens Lehmann was sent off after 18 minutes against Barcelona. Sol Campbell headed 10 men in front, Arsenal held the lead until the 76th minute, and goals from Samuel Eto’o and Juliano Belletti settled it 2-1. Wenger never got that close again.
The Round of 16 Became a Wall
What followed was harder to explain away. From 2010-11 to 2016-17, Arsenal were knocked out in the last 16 in seven consecutive seasons. Barcelona did it twice, Bayern Munich three times, and Milan and Monaco took care of the other two.
The pattern inside those ties matters more than the list. Arsenal kept losing the home leg first and then chasing the tie away from home. They lost 1-3 to Bayern Munich at the Emirates in 2013 and 1-3 to Monaco in 2015, won the second leg 2-0 in both cases, and went out on away goals with the aggregate level at 3-3 each time. The performance they needed had arrived a fortnight too late. When there was no recovery at all, the margins were worse: 0-2 at home to Barcelona in 2016 followed by a 3-1 defeat at the Camp Nou, and the seventh and final exit of that run, against Bayern in 2017, finished 10-2 on aggregate.
What the Stadium Move Cost
Some of it was money. The Emirates opened in 2006 and the debt attached to it shaped Arsenal’s transfer policy for the best part of a decade. While Barcelona, Real Madrid and Bayern were buying finished players, Arsenal were selling theirs. Cesc Fabregas, Samir Nasri, Robin van Persie and Emmanuel Adebayor all left in that stretch, most of them to direct rivals.
A squad that loses its best player every summer can still qualify for the competition, and Wenger’s sides almost always did. Winning it asks for something else, which is the ability to lose an injured centre-back in February without the level dropping for a month.
Where Arsenal Have to Be Better
Three things separate the clubs that lift the trophy from the ones that keep arriving. The first is control across two legs. Arsenal’s exits have come again and again from conceding cheap goals at home, which turns the second leg into a chase against a side that only has to defend. The second is depth. A knockout run stretches from February to May alongside a title race, and the clubs that survive it carry two players of a similar standard for every position.
The third is composure in one decisive match, which is the hardest to coach and the only one that has beaten Arsenal in both finals. Anyone weighing up Champions League betting markets on Arsenal is pricing a squad with a strong league record against a thin history of closing out European nights.
The Arteta Version of the Same Question
Mikel Arteta has already gone further than Wenger managed after 2006, reaching a quarter-final, a semi-final and then the 2026 final in Budapest, where Paris Saint-Germain won on penalties. The defensive record that carried Arsenal to the 2025-26 title is the base a European run is built on, and it is a better base than most of Wenger’s teams had.
The last step is still the unproven one, and it is the same step that beat his predecessor. Arsenal have twice reached a final and twice found a way to lose it, once to a red card inside 20 minutes and once from 12 yards. Until that changes, the trophy stays a question rather than an expectation, and Napoli away is where the next set of answers starts.
