Arsene Wenger's side reached the last 16 despite 2-0 defeat to Napoli.
Arsenal qualified for the last 16 despite losing 2-0 to Napoli, a result which sees them finish second in Group F behind Borussia Dortmund.
Gonzalo Higuain put Napoli ahead on 76 minutes, and after Mikel Arteta was sent off, Jose Callejon scored a second in injury-time.
It was not enough for the Serie A side, however, as they went out thanks to Dortmund’s late win against Marseille in the group’s other match.
And the Arsenal players were realistic in their appraisal, in particular Aaron Ramsey, who started the game on the bench.
Ramsey Tweeted: “A poor performance but we're through and now can focus on Saturday. Thanks in particular to the fans who travelled out to Italy.”
There was high praise for one of Arsenal’s centre-backs, however, with young striker Benik Afobe impressed with the display of Laurent Koscielny on a night when Arsenal needed to show their defensive resolve.
He Tweeted: “I think Laurent Koscielny is the best centre back in the Premiership. Quick, strong and intelligent. What do you all think? Opinions..”
