Granit Xhaka is facing a fight to save his Arsenal career as the club fired a stark warning over growing indiscipline on Monday.
Gunners boss Arteta, who has been unequivocally backed by club chiefs, branded Xhaka's conduct 'unacceptable' after the midfielder was sent off for grabbing Burnley midfielder Ashley Westwood by the throat during the demoralising 1-0 loss on Sunday night.
Sportsmail understands that despite having played regularly for Arsenal since Arteta's arrival last year - the club are open to offers for the Switzerland international.
His lack of discipline at the Emirates on Sunday night and Arteta's subsequent public criticism will only serve to reinforce internal beliefs that Xhaka is dispensable.
