Arsenal begin their latest Champions League campaign against Napoli on Wednesday carrying one of the strongest league-phase records anywhere in Europe.
Mikel Arteta’s side travel to the Stadio Diego Armando Maradona after winning all three Premier League matches this season, but their recent record in Europe’s biggest competition is arguably even more impressive.
Arsenal have won 12 consecutive Champions League league-phase matches heading into the trip to Italy.

Arsenal have won 12 straight Champions League league-phase games
The run stretches back to Arsenal’s 1-0 defeat away to Inter on Matchday Four of the 2024/25 competition.
Since then, the Gunners have won every Champions League league-phase fixture they have played.
UEFA’s official Napoli vs Arsenal match facts confirm the winning sequence now stands at 12 matches.
There is another remarkable attacking statistic behind that run.
Arsenal have scored at least three goals in each of their last six league-phase matches.
That is significant before facing a Napoli side which has already shown defensive vulnerability this season.
Our analysis of Napoli’s form before facing Arsenal explains how Massimiliano Allegri’s side have suffered consecutive Serie A defeats, including surrendering a 2-0 lead against Inter.
Arsenal arrive with a very different momentum.
Arsenal’s wider European record is even stronger
The 12-match winning run forms part of a much longer period of Champions League consistency.
Arsenal have lost only two of their last 30 group-stage or league-phase fixtures, winning 24 and drawing four.
Last season was particularly impressive.
Arteta’s side became the first club to win all eight league-phase matches under the current Champions League format before advancing all the way to the final.
They also finished the competition with the fewest goals conceded, seven, and the most clean sheets, nine.
That provides important context around Arsenal’s ambitions this season.
Reaching the final is no longer enough simply to describe a successful European campaign.
Arteta’s squad will be expected to challenge again.

Napoli face another Arsenal opening-night record
Wednesday also brings another sequence into play.
Arsenal are unbeaten on the opening matchday of their last nine European campaigns, recording seven victories and two draws. Their last Matchday One defeat came against Dinamo Zagreb during the 2015/16 Champions League.
Napoli’s own European form provides an interesting contrast.
The Italian side have won only two of their last ten Champions League matches, while also losing their last three in the competition against English opposition.
Arsenal’s historical meetings with Napoli have also provided encouragement, as examined in our Napoli vs Arsenal head-to-head guide.
None of those statistics guarantee another victory.
Naples remains one of the most demanding away environments Arsenal will encounter during the league phase.
But Arteta’s side do not travel to Italy merely hoping to make a good start.
Their recent Champions League record means another victory would continue a remarkable European sequence which has now lasted almost two years.
