Emery told Xhaka he was no longer part of the Gunners" leadership group and said the Switzerland worldwide "accepted' the decision.
The Swiss worldwide swore and threw the captain's armband to the floor after being booed as he was substituted against Crystal Palace 10 days ago.
In fact, Unai Emery even extended his punishment for Xhaka to not including him in the matchday squad for this afternoon's match against Vitoria SC, which the Gunners ended up drawing.
It will be the third successive game Xhaka has missed, following his absence from Arsenal's Carabao Cup fourth-round defeat to Liverpool and their Premier League draw against Wolves.
"But I was speaking with him this morning and also I decided he is not one of the captains in our group". When you look around the Arsenal XI, only Aubameyang and Guendouzi truly lead by example, and it's no coincidence that the 2 of them have been by far Arsenal's best players this season, and single-handedly won them a few matches from losing positions.

Xhaka is seen as one of if not the best players in Switzerland, hence he captains his country on worldwide duty.
Aubameyang replaces Granit Xhaka who has been demoted following his fan outburst. "They are the four captains and the first now is Aubameyang", said Emery.
"My feeling of not being understood by the fans, and repeated abusive comments at matches and in social media over the last weeks and months have hurt me deeply". My focus is for tomorrow. Should Arsenal's fans single out one player to abuse given most of their team have been underperforming? No.
