Pierre-Emerick Aubameyang's controversial goal gifted Arsenal their first win of the Premier League season, but they were made to work hard by Norwich City.
The Canaries battled hard and were the better side for portions of the game, but their attacking play lacked a cutting edge and Arsenal eventually ground them down.
City are the only side in the top-flight to remain pointless after four matches and move to the bottom of the table. They welcome Watford to Carrow Road next weekend in a game that already feels pivotal.
