Arsenal came into this season on the back of a busy summer transfer window where they spent around £250m and brought in eight players to propel another push for the Premier League title.
As they swept aside Nottingham Forest 3-0 with five of those new signings starting, the Gunners showed why such aggressive recruitment was justified.
Mikel Arteta's side were without key trio Bukayo Saka, Kai Havertz and William Saliba through injury, while skipper Martin Odegaard limped off in only the 18th minute.
But it mattered little as Arsenal showed their strength in depth to cruise to an impressive success.
