Chelsea boss Frank Lampard admits Ethan Ampadu will leave on-loan this season.
The Wales midfielder, 18, was not on the plane for Chelsea's pre-season tour to Japan and is staying at home to thrash out a temporary move away.
Lampard said: “Ethan is not here as we're looking at the possibility of his going on loan for the season.
“I tried to sign Ethan on loan at Derby last year, so I'm a big fan, but with the minutes he played last year, I have to think of the bigger picture and the interests of Ethan and of Chelsea.
“The idea that he could play a lot of games somewhere is good for him and we haven't brought him here while that is up in the air."
