Granit Xhaka was stripped of the captaincy following his angry response to Arsenal fan abuse and Emery has now appointed his star striker as “the first captain”.
Emery said: “The first captain is Aubameyang because he is experienced and he has the respect of the dressing room.
“He was the top scorer last year in the league and I know he needs time to take that responsibility 100% but we will support him.
“Every player will support every captain (Aubameyang, Hector Bellerin, Mesut Ozil and Alexandre Lacazette) and we are going to support him as first captain.”
Emery went on to explain that Xhaka has ruled himself out of playing at the weekend.
He added: “I spoke with him on Tuesday for how he is feeling now and his mind because he is training well but he said to me he can’t play.
“We are going to wait.”
