Sokratis says it doesn't matter who is captain of Arsenal.
Unai Emery stripped Granit Xhaka of the armband this week after his angry reaction at being jeered by his own supporters against Crystal Palace.
Pierre-Emerick Aubameyang will take over the duty this weekend against Leicester City.
"I think it is the first time he is a captain," Sokratis said.
"For me it's important that Aubameyang first has to score, he has to do his work. The captaincy or who has this [armband] on the pitch, I don't think it is very important.
"He is a very good guy, but who has the captaincy is not very important. It is important that all the team is good in the dressing room. We are like a family. In the end who brings to the pitch the captaincy is the last thing."
