Pierre-Emerick Aubameyang could start the second leg of Arsenal's Europa League last-16 tie with Olympiakos on Thursday but will have to "earn his place", said manager Mikel Arteta.
The striker started in the 3-1 first-leg victory over Olympiakos in Greece.
"Everybody has to obviously perform at the highest level to earn their place in the team," said Arteta.
"There is no exception [with Aubameyang] and we will try to put a really competitive team out to try to win again.
"It was dealt with on the day, its been resolved in a really positive way and we move on.
