Arsenal's Champions League Journey Begins in Naples

Arsenal’s long road back to the Champions League final starts in a city that worships a No. 10 and lives for European nights.

Fresh from dismantling Chelsea in the Premier League, Mikel Arteta’s side leave the comfort of London for the chaos of Naples on Wednesday, stepping into a Stadio Diego Armando Maradona that can swallow visiting teams whole if they show the slightest hint of doubt.

This is no gentle reintroduction. It’s a stress test from day one.

From Budapest heartbreak to a new climb

Arsenal arrive in Italy carrying both scars and certainty.

Four months ago in Budapest, they stood two kicks from the Champions League trophy before Paris Saint-Germain wrestled it away in a penalty shootout. The images from that night still linger: exhausted legs, tight faces, the sense of a team that had emptied itself over a brutal league campaign and finally ran dry when it mattered most.

Yet that defeat also drew a thick line through the club’s recent history.

Since returning to the Champions League under Arteta after the 2022/23 season, Arsenal have climbed the ladder step by step: quarterfinals in 2023/24, semifinals in 2024/25, runners-up last season. There is only one rung left. One that has always slipped through their fingers.

Winning this competition would change their status overnight. From contenders to conquerors. From a modern heavyweight to part of the sport’s permanent royalty.

The journey restarts on Wednesday, and the margin for error is brutally small.

The new Champions League maze

For the third straight year, Arsenal open in the league phase, the modern format that has turned the old group stage into a mini-marathon.

Eight games. Eight different opponents. Two drawn from each of UEFA’s four seeding pots, ordered by coefficient and recent success. Champions and heavyweights at the top, debutants and qualifiers at the bottom. On paper, it’s a spread. In reality, it’s a minefield.

Finish in the top eight and you skip straight to the last 16 with a bye. Fall below that, and the path becomes longer and more treacherous.

Arsenal have made a habit of doing it the clean way. They’ve earned that bye in each of the last two seasons, finishing first outright last year. That’s not a dream this time. It’s the standard they’ve set.

Which is why a strong start matters. Eight matches can feel like plenty, but one bad week can drag you into the traffic jam of mid-table. Arsenal open away, again, and away days in this format have a habit of defining seasons.

Their league phase schedule is unforgiving but glamorous:

• Napoli (A) – September 9
• Lille (H) – October 13
• Bayern Munich (A) – October 21
• Slavia Prague (A) – November 4
• Borussia Dortmund (H) – November 24
• Real Madrid (H) – December 9
• Real Betis (A) – January 20
• Sabah FK (H) – January 27

There are no dead rubbers in that run. Every date carries weight. But the tone of the entire campaign will be set under the Neapolitan floodlights.

Napoli: wounded, reshaped, and dangerous

Look at the table and you might relax. You shouldn’t.

Napoli sit 13th in Serie A with a 1-0-2 record, their early domestic form as uneven as their summer rebuild. On the surface, it’s a side still searching for rhythm. Beneath that, there’s enough quality to cause real problems.

Their two defeats have come against Inter Milan and Como, both in the top three. They’ve been juggling injuries to key players. The picture is more nuanced than a glance at the standings suggests.

This is a club only two years removed from winning Serie A in 2024/25, their second league title in five seasons. They lifted the Supercoppa Italiana last year as well. In Italy, their credentials are established. The question is whether they can translate that into Europe, where their recent history has been far less kind.

Last season’s Champions League campaign was a mess. Just two wins in the league phase, an early exit in January, and a sense of a team that never quite found its level on the continental stage. They are not among the favourites this year, but they have more than enough to reach the knockouts if they get their act together.

The squad is talented, but there’s a clear fault line: the No. 9.

Victor Osimhen left for Turkey two seasons ago. Romelu Lukaku followed him out the door this summer, also to Turkey. The new man through the door is Rasmus Højlund from Manchester United. It’s a smart, if not headline-grabbing, signing rather than a marquee statement, and he walks into a dressing room that already contains familiar Premier League faces.

Scott McTominay, also formerly of Manchester United, is there, though currently sidelined with an arrhythmia. Kevin De Bruyne, once the heartbeat of Manchester City, brings vision and experience that can still tilt games at the highest level. Around them, Napoli have added Alisson Santos from Sporting, Vanja Milinković-Savić from Torino, and Benoît Badiashile on loan from Chelsea, along with Costantino Favasuli, Mattia Esposito, and Dinis Rodrigues to deepen the squad.

They’ve lost 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. It’s been a churn rather than a tweak.

Injuries complicate matters further. Alessandro Buongiorno (knee), Luca Marianucci (ligament), McTominay (arrhythmia), and Giovani (hernia) are all out. It leaves Massimiliano Allegri with decisions to make and gaps to patch.

Allegri under the spotlight

Napoli’s biggest unknown isn’t in the penalty area. It’s on the touchline.

Massimiliano Allegri took over after Antonio Conte’s departure at the end of the 2025/26 season. His record in Serie A is beyond dispute; he is one of the most decorated coaches of his generation. Yet his last league title came with Juventus in 2018/19. The game has shifted, and the pressure in Naples is very different to the controlled environment he once enjoyed in Turin.

Conte restored Napoli’s domestic edge. Allegri is being asked to sustain it and add European progress on top. It’s a delicate assignment, and the Champions League will define how his tenure is judged.

A strong performance against Arsenal would buy him time and belief. A flat display at home, on a night like this, would do the opposite.

Arsenal’s standard, Arsenal’s burden

Arsenal know this stadium. They know this opponent. Their all-time record against Napoli stands at 3-0-1, a healthy edge that counts for something in preparation but nothing once the whistle goes.

They arrive as Premier League champions for the first time in over seven years, with three wins from three to open their domestic defence. The swagger is there. So is the expectation.

This is what Arteta has built: a team that no longer sneaks into Europe hoping for a kind draw, but one that walks into the Champions League with a clear target on its back and a clear goal in its mind.

Wednesday’s match is officially just league phase, matchday one:

• 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 the Paramount+ and Prime Video apps

On paper, it’s one of eight. In reality, it’s the first step on the only progression left for this Arsenal side.

They have climbed every stage of this competition under Arteta. Now they stand at the foot of the last mountain. The question is no longer whether they belong here.

It’s whether they are finally ready to finish the climb.
