Chelsea are considering a January loan move for Ethan Ampadu.
The Wales international has yet to appear under Maurizio Sarri this season.
And the Blues are weighing up whether loaning the 18-year-old in January would be better for his development, according toGoal.
Derby County and Aston Villa are the frontrunners, with both clubs having connections to Chelsea through Frank Lampard and John Terry.
Rams boss Lampard already raided his old club in the summer, picking up Mason Mount and Fikayo Tomori on loan deals.
Meanwhile, Lampard's former teammate Terry became an assistant at Villa when Dean Smith took over as manager last month. Chelsea striker Tammy Abraham is also on loan at Villa Park.
Ampadu made seven appearances under Antonio Conte last season.
