Former Real Madrid star Karim Benzema walked out of an Al-Ittihad training session this week.
The Frenchman is said to have refused to follow his manager's orders during a routine session.
Coach Marcelo Gallardo had ordered the Frenchman to train by himself during a session.
However, Benzema refused and is said to have stormed off the field in anger, per Marca.
Benzema may be unhappy at the club, but he does not appear to have any exit plan.
No European team went in for him during the winter window, despite links to several Premier League clubs.
