Noni Madueke’s double and another Champions League goal for Gabriel Martinelli helped the Gunners to a 3-0 win over Club Brugge.
Mikel Arteta’s much changed side continued their perfect record in Europe, having won all of their six games in the competition this season.
Madueke opened the scoring with a superb strike from distance on 25 minutes before heading in a second just after half-time.
And Martinelli became the first Arsenal player to score in five Champions League games in a row with a wonderful curling strike into the corner.
