Dylan Williams: Chelsea sign teenage defender from Derby County

Last updated on 57 minutes ago.

Dylan Williams, who turned 18 in December, has made nine first-team appearances for the Rams.

The Rams have sold four players in this transfer window, including Dylan Williams, who was sold to Chelsea.

Williams joined the holders for an undisclosed fee.

Williams made his Rams debut at the age of 17 in the third-round of the FA Cup.

His departure is the same as those of David Marshall, Phil Jagielka and Graeme Shinnie.

Williams is expected to play a role in the short term.

Derby are second bottom of the Championship, eight points from safety, after Saturday's derby defeat.

Derby has battled hard to stay in League One under manager Wayne Rooney despite being placed in administration in September.

If they can't conclude a deal to buy the club, they will have to liquidate.

The Binnie family submitted a bid for the club on Friday.

Derby's debts are reported to be more than double that, with compensation claims from other English Football League clubs.

The administrators of the club wanted to name a preferred bidder earlier this month, but they need to prove how Derby will be funded for the rest of the season.
