Ampadu did not travel with the first-team to Japan as Chelsea seek a loan deal for the midfielder. "We are looking at the possibility of Ethan going on loan for the season," manager Frank Lampard said. "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, in the interest of Ethan and of Chelsea, the idea he can play a lot of games somewhere could be good for him. That's not done yet but we haven't brought him here while that's up in the air. I really wanted to work with Ethan this year. That's a slight disappointment, but it's to benefit of him. In midfield and defence we have a lot of quality, so each player is a case by case."

Ampadu (knee) started in Thursday's 2-2 draw with Vidi.

Ampadu injured his knee in while playing for Wales on Friday against Spain, BBC Sport reports.

Ampadu participated in the friendly match with Inter Milan on Saturday.

Ampadu (undisclosed) has been ruled out for the rest of the season.
