Arsenal moved off the bottom of the Premier League standings and scored their first goal of the campaign after captain Pierre-Emerick Aubameyang's scrambled 66th-minute effort gave them a 1-0 home win over Norwich City on Saturday.
Mikel Arteta's side produced an improved performance after their opening three defeats but were made to work hard by a rugged Norwich side before Aubameyang, who missed two first-half chances, broke the deadlock.
The Gabonese striker fired wide in the 10th minute and was denied in the 20th by a superb save from visiting goalkeeper Tim Krul before Takehiro Tomiyasu volleyed over the bar for the dominant hosts on the stroke of half time.
A timely intervention by left back Brandon Williams kept out a Nicolas Pepe sitter for Arsenal shortly after the break before the Ivorian played a major role in Aubameyang's goal, given after a VAR check for offside.
Pepe twice hit the post within a few seconds from a flowing move and the second rebound fell kindly to Aubameyang, who was perfectly positioned to tuck the ball into an empty net.
The result lifted Arsenal to 16th place on three points from four games while Norwich, who are still looking for their first point of the season, slipped to the bottom of the table.
