Arsenal have confirmed that captain and talisman Pierre-Emerick Aubameyang will still be absent for Tuesday's Premier League game at Southampton.
The striker was omitted at the 11th hour for Saturday's 1-0 FA Cup loss against the same opponents at the same venue due to unspecified personal issues.
After the match, manager Mikel Arteta voiced his fears that the 31-year-old could be absent for an even longer time and it has now been confirmed that he will be forced to sit out at least one Premier League match.
