Pierre-Emerick Aubameyang scored a second-half tap-in to give Arsenal their first goal and first points of the Premier League season as they sent Norwich to the bottom table.
Both sides ran out at the Emirates Stadium having lost their opening three league games of the campaign and, following a game lacking quality, Aubameyang settled the contest as his close-range finish earned the Gunners a 1-0 victory.
Even then there was a nervy wait as a VAR check for offside ultimately went the way of the home side, who travel to Burnley next weekend with something to build on.
Arsenal boss Mikel Arteta made seven changes from the galling defeat at Manchester City before the international break as deadline-day signing Takehiro Tomiyasu started at right-back.
Arteta will be hoping this is a turning point for his side, who had not even scored in their first three games, with Aubameyang again proving the scourge of Norwich having hit braces in both games against them in the 2091/20 season.
The goal came after Nicolas Pepe's shot was tapped on to the post by Tim Krul and the ball struck a combination of Pepe and Brandon Williams, hitting the opposite post and rolling into the path of Aubameyang to turn home into an empty net — with the goal standing after a brief VAR check for offside.
The Gabon international had a fine opportunity to wrap up the points but shot straight at Krul, who them provided a fine stop to prevent Emile Smith Rowe doubling the lead.
Arsenal hearts were in mouths as the clock hit 90 minutes, a low cross into their box fell to Teemu Pukki but Gabriel Magalhaes was on hand with a last-ditch challenge.
