Aubameyang was again missing for the game last night due to a "personal issue".
All signs are that he will also miss the weekend game with Manchester United as Arteta said: "No [there's no update] but I love how they support each other and how they protect each other. Auba is having a difficult time. We are all behind him and this win is for him."
On the absent Kieran Tierney, he added: "I don't know. He wasn't available against Southampton in the FA Cup, he was injured. He's still injured today. Let's see how he progresses for the game against Man United."
