Goals from Martin Odegaard, Gabriel and Mohamed Elneny gave the Gunners the commanding lead in Piraeus and a victory over Tottenham in the north London derby on Sunday will have given them even more confidence.
Pierre-Emerick Aubameyang was dropped from the win over Spurs due to disciplinary issues after turning up late, but is expected to return on Thursday night.
‘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.’

Bukayo Saka is the only serious injury concern for Arsenal and is unlikely to play after picking up a hamstring problem in the north London derby at the weekend.
Arteta suggested the teenager could be involved but that seems an unnecessary risk given the options available to the manager and the victory in the first leg.
