Arsenal made it three wins in the Europa League with a hard earned 1-0 success at Bodo/Glimt on Thursday night.
The Norwegian champions boasted a formidable home record going into the game, having won their last 14 European games at the Aspmyra Stadion - including a 6-1 victory over Jose Mourinho's Roma last season.
So Mikel Arteta named a stronger team than many expected, with William Saliba, Ben White, Martin Odegaard and Bukayo Saka all starting.
And it was Saka who scored the only goal of the game in the first half, albeit with a fortunate finish which saw the ball deflect in off his chest after his initial shot had been blocked.
Bodo did cause the Gunners some problems, especially in the second half, but they failed to really test Matt Turner with any shots on goal.
The win means Arsenal will now secure qualification through to the knockout stages, should they beat PSV Eindhoven at Emirates Stadium next Thursday night.
