The legendary Chelsea midfielder has long been the favourite to succeed Maurizio Sarri at Stamford Bridge.
And the 41-year-old was seen arriving at the ground on Wednesday evening.
He was seen going through a door at the Shed End and all the details of his new position at the club’s helm have been finalised.
No doubt Lampard is collaborating with the club’s media departments ahead of a grand unveiling.
Despite the fact that his arrival is widely known, Derby’s announcement may have come too soon for the Blues, who would want to inform fans themselves.
Lampard will be joining his former side in his dream job just one season after beginning his managerial career.
He led Derby to the Championship play-off final last term where they suffered defeat by Aston Villa at Wembley.
