Arsenal's Champions League Journey Begins in Naples

Arsenal’s long road back to the Champions League final starts in the heat of Naples, with the memory of Budapest still burning.

Fresh from dismantling Chelsea in the Premier League, Mikel Arteta’s side swap London for the Stadio Diego Armando Maradona on Wednesday, opening a European campaign that now comes with a single, unavoidable demand: go one better.

From heartbreak to hard edge

Arsenal were two kicks from immortality last season. A penalty shootout defeat to Paris Saint-Germain in the final in Budapest didn’t just sting; it underlined how far and how fast this team has climbed under Arteta.

Since returning to the Champions League after the 2022/23 season, the trajectory has been brutally clear. Quarterfinals in 2023/24. Semifinals in 2024/25. Final last season. Every year, one step higher. There is only one step left.

Winning this competition is no longer a dream for Arsenal; it’s the missing line on the résumé of a side that has already reclaimed domestic authority. The Premier League champions are no longer grateful participants. They arrive as contenders with a score to settle.

That mission begins again on Wednesday night.

Navigating the new Champions League maze

For the third straight year, Arsenal enter UEFA’s revamped league phase, a format that still feels strange but now comes with familiar stakes. Eight games. Eight different opponents. Two teams drawn from each of four pots, ranked by UEFA coefficient.

Pot 1 is reserved for the heavyweights – champions and serial performers. Pot 4 is where the newcomers usually live. Arsenal know this landscape well now, and they’ve mastered it: top-eight finishes in each of the last two seasons, both times earning a bye into the knockouts. Last season, they didn’t just qualify; they finished first outright.

That is the standard inside the dressing room now. Anything less feels like slippage.

The margin, though, remains thin. Eight games sound generous, but one bad week can drag a giant into the chaos of the playoff round. Starting well matters, and Arsenal must do it the hard way again, opening on the road.

Their league phase schedule is unforgiving but glamorous:

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

Naples first. Munich and Madrid to come. There will be no hiding.

Napoli: wounded, awkward, dangerous

On paper, this looks like a mismatch of early-season form.

Arsenal have opened their Premier League title defence with three wins from three, carrying the sharpness and swagger of a team that expects to be in the latter stages of this competition again.

Napoli, by contrast, sit 13th in Serie A with a 1-0-2 record. Two defeats in their first three league games hint at a side still finding its feet.

Scratch the surface, though, and the picture shifts. Those losses came against Inter Milan, currently third, and Como, who sit second. Napoli have juggled injuries to key players. They are not playing like relegation fodder; they are playing like a talented team in transition.

Only two years ago, they were champions of Italy, lifting the Serie A title in 2024/25 – their second Scudetto in five years. Last season they added the Supercoppa Italiana, the local equivalent of the Community Shield, to underline their domestic pedigree.

Europe, however, has not been as kind. Their last Champions League outing was a mess: just two wins in the league phase, and an exit in January. Like Arsenal, they have never quite cracked this competition. Unlike Arsenal, they are not expected to this year.

But they are capable of dragging a heavyweight into a fight.

Allegri’s challenge and a reshaped squad

Massimiliano Allegri stands at the centre of Napoli’s uncertainty. The veteran coach replaced Antonio Conte at the end of the 2025/26 season, returning to a league he once dominated but hasn’t conquered since winning the title with Juventus in 2018/19.

His reputation is secure. His recent record is not. This season asks a blunt question: can he sustain the level Conte restored, or will Napoli drift?

He must answer it with a squad that has been subtly but significantly reshaped.

Up front, there is a clear void. Victor Osimhen left for Turkey two seasons ago. Romelu Lukaku followed him out this summer, also heading to Turkey. That’s a lot of goals removed from a side that once bullied defences.

Napoli’s response was to move for Rasmus Højlund from Manchester United. It is not the kind of signing that shakes Europe, but it is a calculated bet. Højlund joins an established core that includes another former United player in Scott McTominay and Manchester City great Kevin De Bruyne, whose presence alone raises the ceiling of any attack he plays in.

Around them, the club has been busy:

Incomings:
Rasmus Højlund (Manchester United)
Alisson Santos (Sporting)
Vanja Milinković-Savić (Torino)
Benoît Badiashile (loan from Chelsea)
Costantino Favasuli (Catanzaro)
Mattia Esposito (Sorrento)
Dinis Rodrigues (FC Sion)
Departures:
Miguel Gutiérrez (Leverkusen)
Giovanni Simeone (Torino)
Romelu Lukaku (Fenerbahçe)
Alessandro Zanoli (Udinese)
Luis Hasa (Frosinone)
Walid Cheddira (Avellino)
Alessio Zerbi (Frosinone)

The injury list complicates things further. Alessandro Buongiorno (knee), Luca Marianucci (ligament), Scott McTominay (arrhythmia) and Giovani (hernia) are all sidelined, stripping Allegri of options and experience in key areas.

This is not the ideal backdrop for welcoming the Premier League champions. It is, however, the sort of volatile scenario that can produce a snarling, defiant performance in front of a home crowd that demands a response.

Arsenal’s history and the weight of expectation

Arsenal arrive in Naples with the numbers on their side. Their all-time record against Napoli stands at 3-0-1, and they carry the authority of champions, both in England and in their recent European form.

They also carry expectation. Internally, the bar is set: top eight in the league phase, a bye into the knockouts, and a return to the deep end of the competition. Externally, the narrative is even simpler. After quarterfinals, semifinals, and a final, anything short of lifting the trophy will feel like a missed opportunity.

The details for Wednesday are locked in:

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 apps

Arsenal know what this stage demands now. Napoli know what it means to topple giants at home. One club is chasing the last step to greatness; the other is fighting to prove it still belongs among Europe’s elite.

Only one of them can afford a slow start.
