The Gunners eased into the Carabao Cup quarter-finals on Tuesday night.
Calum Chambers and Eddie Nketiah were the unlikely heroes for much-changed Arsenal, who will have their eye on winning this competition for the first time since 1993.
Chambers scored with his first touch just 23 seconds after replacing the injured Ben White - his first goal for two years.
Nketiah then wrapped up the win against his former loan club, making it six victories from the last eight matches for resurgent Arsenal.
Meanwhile, Leeds’ difficult start to the 2021/22 season continued as they now focus on trying to move away from the Premier League’s bottom three.
Dan James and Jack Harrison had the best chances on the night for Marcelo Bielsa’s side, but could not find a way past Bernd Leno.
