With three progressive games against individual strugglers Brighton (home), Watford (away), and West Ham (home) to come, Norwich will in any case accept they can turn it around.
Be that as it may, it looks increasingly likely the Canaries will make a brisk come back to the Championship, which they won last season.
After an error by Josip Drmic, Aubameyang turned supplier for Swiss midfielder Granit Xhaka to clear his first goal for the club since March 2019, before Aubameyang added another.
Cedric Soares finished the defeat, the substitute scoring from outside the penalty area 229 seconds after going ahead for his Gunners debut.
Norwich hit the woodwork through Ben Godfrey when the game was goalless, with six games remaining with seven safety points, while Emiliano Martinez made a fine save to keep out the free-kick of Kenny McLean.
This was a profoundly satisfactory come back to the Emirates Stadium for Mikel Arteta’s side as they marked their first serious home match since 7 March with easy success.
This was their fourth straight defeat since the re-start, while they have not scored a top-flight goal for over six hours.
Having lost their initial two matches after the restart, the Gunners have now won their past three, have a FA Cup semi-final to anticipate, while Aubameyang is at the top of the Premier League scoring charts on 19 goals with Leicester’s Jamie Vardy.
Aubameyang, the fastest Arsenal player to 50 Premier League goals, is yet to vow his drawn-out future to the Gunners, with his present contract due to terminate in 2021.
The Gunners will trust he can be persuaded to stay after another inspirational performance by the forward, who has 51 league goals for Arsenal in 79 games.
