Bukayo Saka scored the winner against Bodo/Glimt on Thursday night but manager Mikel Arteta says there were elements of the winger's display that he can still improve upon.
The Gunners ended the Norwegian side's run of 14 consecutive home European wins, leaving the Arctic Circle with a hard-fought 1-0 win after Saka scored the only goal of the evening in fortuitous circumstances.
The goal was all the Englishman's own work as he played a one-two to get in behind before seeing his first shot blocked back into his path and into the goal off of him.
