Chelsea boss Jose Mourinho has axed Kevin de Bruyne for their Champions League trip to Steaua Bucharest.
The Daily Mail says De Bruyne, 22, is unhappy with his treatment having rejected opportunities to move back to Germany, where he had a successful season on loan at Werder Bremen last season.
Borussia Dortmund wanted to sign him permanently but Mourinho convinced him he would play a part in the Chelsea first-team this season.
The Belgian international is concerned about his place at the World Cup and will consider asking for a loan move in January if he cannot persuade Mourinho to change his mind and recall him to the squad.
