Mikel Arteta's side are in the midst of a demanding seven days that started with a 1-0 victory at Tottenham in the north London derby last Sunday. The Gunners now head to Atalanta to kick off their European campaign before Sunday's vital trip to Premier League champions City.
Arsenal's daunting schedule was made trickier by the absence against Tottenham of key midfielders Declan Rice and Martin Odegaard due to suspension and injury, respectively. But, with Jorginho filling in admirably for Rice, Arsenal ground out their third win in four league games this term thanks to Gabriel Magalhaes' second-half header.
Rice should be back in the starting line-up against Atalanta, but Arteta is still waiting to discover when skipper Odegaard will be able to return from the ankle problem he suffered on Norway duty.
