Arsenal confirmed top spot in their Europa League group as Kieran Tierney's first-half strike saw them dispatch Zurich 1-0 on Thursday night.
The defender opened the scoring after a tense opening and the hosts held their Swiss opponents at bay for the remainder of the game to win Group A and render PSV Eindhoven's victory at Bodo/Glimt irrelevant.
It means Mikel Arteta's side progress straight to the last 16 and will avoid a knockout play-off against a Champions League droput.
