Derby manager Wayne Rooney has confirmed that his side have accepted a bid for Dylan Williams amid reports that Chelsea are in talks for the left-back.
The 18-year-old could make his move to Stamford Bridge before the end of the transfer window in January.
Several reports have linked the youngster with a move to Chelsea and Rooney has now confirmed a bid has been accepted.
And now, head coach Rooney has revealed that Williams is set to leave after he accepted a bid from an unnamed Premier League club.
Speaking to the clubs official media channel, Rooney said: "I've spoken with the administrators, who are working very hard to get everything sorted.
"I've been assured that no one will leave without my say-so. "
We've agreed a fee with a Premier League club for Dylan Williams - I couldn't stand in the way of his opportunity."
This comes as Juan Castillo was granted a move to League One Charlton Athletic.
Williams appears to be signing to go into the academy sides rather than provide back-up for Marcos Alonso in the Chelsea first team.
Ben Chilwell's absence means that the Blues are still in the market for a left wing-back and could look to secure a deal before the end of the window.
