Mikel Arteta said there are no guarantees Pierre-Emerick Aubameyang will return to the starting lineup after he was benched for Arsenal's win over Tottenham Hotspur.
Aubameyang had to watch the derby from the bench after what was described as a “breach of pre-match protocol”, understood to entail arriving at the Emirates later than appointed. His replacement, Alexandre Lacazette, scored the winning penalty.
“We talked, everything has been resolved in a really positive way so we move forward,” he said, although he refused to say whether Aubameyang will face Olympiakos at home on Thursday.
“No, everybody has to obviously perform at the highest level to earn their place in the team,” he said. “There is no exception there and we will try to put a really competitive team out to try to win again."
