Granit Xhaka admits Arsenal selling Pierre-Emerick Aubameyang would be a "great loss".
Aubameyang is approaching the final 12 months of his contract at the Emirates.
Xhaka, who was replaced by Aubameyang as captain during the season, admits his exit would be a damaging blow to the club.
“If that were to happen, it would, of course, be a great loss for the team and the club," he told SportBild.
“Auba is always dangerous and always good for a goal, and as a guy, he's also really great.
“He is always positive, optimistic, helpful and very professional."
