Chelsea are considering a move for RB Leipzig left-back Matthew Bondswell, with the teenager a potential understudy to Ben Chilwell.
The 18-year-old is treading a unique path having left Nottingham Forest in 2018 for Leipzig and currently on loan with second-tier Dutch side FC Dordecht for this season.
He may have little first team experience, and none at the top level, but he has been capped for England at every level from Under-15 to Under-18.
He has done enough to catch the eye of Chelsea, but they are not alone in wishing to snap up the full-back.
The Telegraph reports that West Ham and Sporting Lisbon are also keen on the youngster and there could be something of a tussle for his services in January.
Blues boss Frank Lampard also has Marcos Alonso and Emerson Palmieri at his disposal, but neither are expected to have long futures at the club after falling out of favour under the current manager.
Emerson is likely to return to Italy either in January or next summer, while Alonso has also been linked with a return to Italy, with Inter Milan, but also a switch across London to Crystal Palace.
