Midfielder Granit Xhaka has been stripped of the Arsenal captaincy with Pierre-Emerick Aubameyang taking over, Gunners' boss Unai Emery has confirmed.

Xhaka, 27, was involved in an angry confrontation with home fans during the Gunners' 2-2 draw with Crystal Palace on 27 October.

The Switzerland international was booed as he walked off the pitch at Emirates Stadium, prompting him to cup his ear.

Emery later said Xhaka should have apologised to the club's supporters.

"We make mistakes, we need to apologise and we suggested for him to do that," said Emery at the time. "Really, he knows he was wrong and he feels inside very deep."

However, Xhaka refused to go that far, although he did say he got "carried away" and reacted "disrespectfully" to fans.

"The scenes that took place around my substitution have moved me deeply," Xhaka said in statement on Instagram last month. "I love this club and always give 100% on and off the pitch.

"My feeling of not being understood by fans, and repeated abusive comments at matches and in social media over the last weeks and months, have hurt me deeply.

"People have said things like, 'We will break your legs', 'Kill your wife' and 'Wish that your daughter gets cancer'. That has stirred me up and I reached boiling point when I felt the rejection in the stadium on Sunday."

Xhaka has been left out of Arsenal's squad for their Europa League game in Portugal against Vitoria Guimaraes on Wednesday.
