The Welsh left-back, 23, is wanted by Antonio Conte on the back of his impressive performances, as well as to boost the Blues’ home-grown quota, The Sun has revealed.
Mauricio Pochettino regularly rotates his full-backs, but £20-million-rated Davies is predominantly second choice at White Hart Lane behind Danny Rose.
He put in impressive performances for the Dragons at Euro 2016 as part of a three-man defence – something Conte could utilise in his favoured formation.
League rules state eight home-grown players are required in a matchday squad and Davies fits the bill.
Davies, who moved to north London from South Wales in 2014 for £10m, has made just two appearances for Pochettino’s men so far this season, after injury to England international Rose in recent weeks.
Last season he made 39 appearances in total for Tottenham and Wales and his versatility could be key for Chelsea, who signed Spanish left-back Marcos Alonso on deadline day.
