Andreas Christensen will ask to leave Chelsea in January if he continues to struggle for first-team opportunities, his father and agent has said.
Maurizio Sarri has employed a back four and returned David Luiz to the starting XI alongside Antonio Rudiger, leaving Christensen -- who broke into the team at the expense of Luiz under Antonio Conte last season -- out.
The defender has voiced frustration at the situation, describing his lack of minutes under Sarri as "very difficult."
And in an interview with Danish television, the 22-year-old's father Sten said he did not consider a loan move in the New Year to be a viable option.
