Chelsea are lining up a shock offer for versatile defender Ben Davies, who plays for their big London rivals Tottenham Hotspur.
The Wales international, who can play left-back or centre-back, is on the Blues’ radar, according to ESPN.
Antonio Conte is desperate to improve his defence in January, as well as boosting the club’s home-grown status.
Despite paying £56 million for defenders David Luiz and Marcos Alonso, Chelsea have conceded nine goals in four games.
Davies, 23, is currently playing second fiddle to Danny Rose at Spurs.
