Arsenal Begins Champions League Journey Against Napoli

Arsenal’s road back to the summit of Europe starts in the shadow of Vesuvius.

Fresh from dismantling Chelsea in the Premier League, Mikel Arteta’s side swap London comfort for Neapolitan chaos on Wednesday, opening their Champions League campaign away to Napoli at the Stadio Diego Armando Maradona. It’s the first stop on a long, unforgiving route they now know all too well.

Arsenal’s last step

Arsenal came within touching distance of the trophy last season. Two kicks, to be precise.

Their defeat to Paris St. Germain on penalties in Budapest still hangs over this group. It was a final framed by contrast: Arsenal staggering in after an exhausting league run-in, PSG gliding in with fresher legs and another domestic title barely contested. The scars from that shootout won’t fade quickly, but inside the club it stands as a marker, not a millstone.

Since returning to the Champions League under Arteta after the 2022/23 season, Arsenal have climbed the ladder one rung at a time: quarterfinals in 2023/24, semifinals in 2024/25, finalists last season. There is only one place left to go. The one that has always eluded them.

Winning this competition would change their status permanently. From contenders to confirmed members of Europe’s ruthless elite.

The climb begins again on Wednesday.

Navigating the new format

This is year three of UEFA’s revamped “league phase”, a modern format that has stripped away the old group stage and replaced it with a single table. Eight opponents, eight matches, one long test of consistency.

Each club draws two opponents from each of four seeded pots, based on UEFA coefficient and recent success. Champions and serial performers sit in Pot 1, debutants and qualifiers usually drop into Pot 4. Arsenal, after finishing first in the league phase last season and earning a knockout bye in each of the past two years, know the stakes.

Finish in the top eight and you skip the first knockout round. Anything less, and the path gets steeper.

Eight matches might sound generous, but the margin for error is slim. One bad week, one flat performance, and the table tightens around you. Arsenal’s expectation, given their recent record, is clear: secure that bye again. But they’ll have to start this campaign away from home. Again.

Their schedule is loaded with storylines:

• Napoli vs Arsenal – Wednesday, September 9
• Arsenal vs Lille – Tuesday, October 13
• Bayern Munich vs Arsenal – Wednesday, October 21
• Slavia Prague vs Arsenal – Wednesday, November 4
• Arsenal vs Borussia Dortmund – Tuesday, November 24
• Arsenal vs Real Madrid – Wednesday, December 9
• Real Betis vs Arsenal – Wednesday, January 20
• Arsenal vs Sabah FK – Wednesday, January 27

Naples first. Munich and Madrid still to come. No soft landing.

Napoli: better than the table says

On paper, Arsenal arrive in far stronger shape.

Three wins from three in the Premier League. Fluid, confident, and already playing with the look of a side ready for another deep European run.

Napoli? Thirteenth in Serie A with a 1-0-2 record, two defeats in their first three league games. That line alone might tempt some into underestimating them. Arteta will know better.

Those losses came against Inter Milan, currently third, and Como, sitting second. Napoli have also been juggling injuries to key players. Strip away the early-season wobble and you find a club only two years removed from winning Serie A in 2024/25, their second domestic title in five years.

They added the Supercoppa Italiana last season too, Italy’s equivalent of the Community Shield. In their own league, their pedigree is not in doubt. The question is what that translates to on Champions League nights, where they have so often fallen short.

Last season’s European campaign was a mess. Just two wins in the league phase, and they were out by January. For a club of their stature, it stung. For a fanbase used to volatility and drama, it was still a disappointment.

They are not among the favourites to lift the trophy this season, but they have the quality to reach the knockouts if they find rhythm quickly.

Allegri’s puzzle

This Napoli side is still searching for a new attacking spearhead.

Victor Osimhen departed for Turkey two seasons ago. Romelu Lukaku followed the same path this summer. Two big personalities and focal points gone from the front line in quick succession.

Napoli moved for Rasmus Højlund from Manchester United, a signing that won’t shock Europe but could quietly stabilise their attack. He joins a dressing room that already contains familiar Premier League faces: former United midfielder Scott McTominay and former Manchester City icon Kevin de Bruyne.

The squad has been reshaped around them. In come Højlund, Alisson Santos from Sporting, goalkeeper Vanja Milinković-Savić from Torino, Benoît Badiashile on loan from Chelsea, Costantino Favasuli from Catanzaro, Mattia Esposito from Sorrento, and Dinis Rodrigues from FC Sion.

Out go Miguel Gutiérrez to Leverkusen, Giovanni Simeone to Torino, Lukaku to Fenerbahçe, Alessandro Zanoli to Udinese, Luis Hasa and Alessio Zerbi to Frosinone, and Walid Cheddira to Avellino.

They will also be missing important names on Wednesday. Alessandro Buongiorno is out with a knee problem, Luca Marianucci with a ligament injury, Giovani with a hernia, and McTominay sidelined by an arrhythmia.

Over all of this stands Massimiliano Allegri.

The Italian took over after Antonio Conte’s departure at the end of the 2025/26 season. His CV in Serie A is stacked, his reputation forged in title races and European nights with Juventus. But he has not lifted a league trophy since 2018/19.

Napoli’s hierarchy brought him in to steady and then elevate. To follow Conte’s success and keep the club climbing, not sliding back into old habits. Whether he can still bend a season to his will at this level is one of the more intriguing questions in Italy.

History and the night ahead

Arsenal know this ground, and they know this opponent. Their all-time record against Napoli stands at three wins and one defeat. It’s a small sample, but it underlines one thing: this is not a venue that has intimidated them in the past.

Napoli, though, welcome the Premier League champions for the first time in more than seven years. The stadium, the city, the occasion – all of it will be primed to rattle even the most seasoned visitors.

The details are set:

• WHO: Arsenal at Napoli
• WHAT: Champions League league phase, Matchday 1
• WHEN: Wednesday, September 9, 3:00pm EST / 12:00pm PST / 8:00pm GMT
• WHERE: Stadio Diego Armando Maradona, Naples
• HOW TO WATCH: Streaming on Paramount+ and Prime Video

Arsenal arrive knowing there is only one way to top last season: win the thing.

The road starts in Naples. Do they treat it like just another away day, or the first step of a season that finally ends with their hands on the trophy?
