Derby are working “on the assumption that Frank Lampard will reach an agreement with Chelsea”, with a manager still in talks with the Blues having been excused from pre-season training.
The Rams revealed last week that they had reluctantly granted permission for their current coach to enter into discussions with the Blues.
A return to Stamford Bridge for Lampard has been mooted for some time.
With Maurizio Sarri having left a role at Chelsea to link up with Serie A champions Juventus, a familiar face has registered on the recruitment radar in west London.
Derby expect a deal to be done, with the Championship club preparing to begin their own search for a new boss.
A statement from the Rams on the club’s official website read: “Derby County Football Club has excused Frank Lampard from reporting back for pre-season training on Monday and Tuesday to allow his discussions regarding a potential move to Chelsea to be concluded as soon as possible.”
