This was Arsenal's first match since Bukayo Saka's quadriceps injury which is set to rule him out for at least six weeks.
Saka's absence meant Noni Madueke was back on his favoured right wing and he put in a positive performance with his direct running a constant threat to the Everton backline.
The England international should have scored after being played through by Declan Rice in the first half but Madueke can be pleased with his display in front of watching England manager Thomas Tuchel.
Eberechi Eze was bright on the left wing after scoring in the midweek Champions League draw with Bayern Munich, while manager Mikel Arteta will be delighted that his side have found a way to score from set-pieces again.
Last season, the Gunners led the league with 25 goals from set-pieces (excluding penalties) and set a new record for goals scored from corners at 19.
And after a fallow opening seven games, Ezri Konsa's goal got them up and running for this campaign.
Konsa and Gabriel have formed one of the best defensive partnerships in the league but on this evidence, their threat in the opposition box further underlined their all-round assets to the team.
