Chelsea boss Frank Lampard admits Fikayo Tomori is likely to leave this month.
The defender was left on the bench for Sunday's FA Cup defeat of Morecambe.
Lampard said, "The situation with Fikayo is open at the moment. There's a possibility that he could be going on loan to get games somewhere else but that has to be right solution for him and the club.
"He was part of my thinking to start today but we're looking at that.
"His attitude has been fantastic in terms of training every day and how he is because it's not easy when we have five centre-backs at the club."
