Glenn Nyberg has been appointed to referee Wednesday's Champions League match between Napoli and Arsenal at the Stadio Maradona. Assistants Mahbod Beigi and Andreas Söderkvist, also from Sweden, will work with him, while Spanish Carlos del Cerro Grande is set to oversee VAR and French Jérôme Brisard will serve as Assistant Video Assistant Referee.

The fixture has also been designated as high risk from a public-order perspective, with around 1,500 travelling supporters expected from England. Around 45,000 tickets have reportedly been sold for the European clash so far.

Arsenal's Champions League squad submission

Arsenal have added 30 names to their Champions League B-List squad and have already submitted their final squad for the competition. The club website has set out the B-List rules clearly: a player can be registered if he was born on or after 1 January 2004 and has met the eligibility criteria through uninterrupted time at the club, while clubs can keep registering players on List B during the season until 00:00 CET the day before a match.

That matters because Arsenal's depth is not just showing up on the team sheet, it is showing up in the registration list as well. The club can keep expanding that part of the squad through the campaign, and Wednesday's opener in Naples comes with that extra layer already in place.

Recent form before the opener

The form line is fairly clean. Arsenal have won all three of their Premier League games, and the club are unbeaten in their last five matches, winning all five and conceding only two league goals in the latest two Premier League games and the Community Shield run included.

Napoli, by contrast, have lost two of their opening three Serie A games this season. They have taken two wins in their last five league matches, but the most recent three show the wobble: L-L-W against Inter, Como and Genoa.

Napoli finished second in Serie A in 2025 and Arsenal finished first in the Premier League in 2025, so the meeting in Naples brings together a side still trying to steady itself and one arriving with a much cleaner start to the season.
