Arsenal manager Mikel Arteta has ruled Pierre-Emerick Aubameyang out of their Carabao Cup quarter-final fixture against Manchester City on Tuesday.
The 31-year-old missed Saturday's 2-1 loss to Everton due to tightness in his calf as the Gunners' winless run in the Premier League stretched to seven matches.
Aubameyang is yet to recover from the injury and he is not expected to feature when Manchester City visit the Emirates Stadium.
