Michael Hector is set to become Chelsea’s 21st loanee of this summer as he nears a move to Frankfurt.
The Bundesliga club had targeted the Blues’ American centre back Matt Miazga but now appear to have turned their attentions to Hector.
The 24-year-old has been training with Antonio Conte’s first-team squad in pre-season but Chelsea want him to gain more top-level experience.
Hector, a boyhood Chelsea fan, spent last season on loan at Reading after a shock £4million move from the Championship club on deadline day last summer.
