Chelsea are reportedly closing in on their first signing of the January transfer window with Derby County defender Dylan Williams inbound.
But he is not expected to be a solution to Thomas Tuchel's troubles at left wing-back, instead being brought in to help with a similar issue in the club's academy.
The German is said to be eager to strengthen in the area with Ben Chilwell set to miss the remainder of the season with a ruptured cruciate ligament, leaving Marcos Alonso as his only option.
