Mikel Arteta says the internal issue involving Pierre-Emerick Aubameyang has been "resolved" but has warned that the forward must earn his place back in the Arsenal team.
Aubameyang was left on the bench for Sunday's north London derby clash with Tottenham after breaching pre-match protocols, with the Gunners subsequently earning an impressive 2-1 victory in his absence.
The Gunners boss has revealed that the striker won't face any further punishment ahead of the Europa League meeting with Olympiacos, but stopped short of confirming whether he will play a part in the second leg tie.
