Chelsea FC are currently eyeing their club legend, Frank Lampard to fill the manager role Maurizio Sarri left to manage Juventus.
If Lampard moves, Chelsea will have to pay £4m to Derby County.
“With pre-season fast approaching for both clubs it is hoped this will allow Chelsea to swiftly conclude their discussions,” a Derby statement read.
“The club will make no further comment until it is appropriate to do so.”
Lampard kicked off his career as a manager last season, leading Derby County to the Championship play-off final but they lost to Aston Villa.
The former England midfielder in 13 years, made 648 Chelsea appearances, winning 11 major trophies.
