The manager said this ahead of their second leg Europa League tie against Olympiacos:“Yes. We talked, everything has been resolved in a really positive way. So we move forward.”Arteta however rejected any notion that Aubameyang would walk his way back into the Arsenal team who host the Greek side on Thursday, stating that the striker had to "earn his place."Arteta said this when quizzed on Aubameyang starting against Olympiacos:“No, everybody has to obviously perform at the highest level to earn his place in the team and there are no exceptions there. We will try to put out a really competitive team to try and win the game.”Arteta confims Aubameyang was in line to start for Arsenal on SundayArsenal v Manchester City - Premier LeagueArteta refused to specify why exactly the 31-year-old was not involved in the derby even after confirming he was initially in the starting XI. The manager tagged the occurrence as a "disciplinary issue"."He was going to start the game. We have had disciplinary issues, we have drawn the line and we move on. He's on the bench," he said."We keep that internally. We have a process we have to respect for every game and that’s it."Arsenal are already halfway through to the quarterfinals of the Europa League as they beat Olympiacos 3-1 in Greece last week.

Securing the Europa League would automatically qualify them for the Champions League next season.
