Michael Emenalo is on the verge of being named as Chelsea's new sporting director, BBC Sport understands.
The 45-year-old former Nigeria international will fill the role vacated by Frank Arnesen, who has taken up a similar position at Hamburg.
Emenalo joined the club in 2007 as head opposition scout and was made assistant first-team coach after the departure of Ray Wilkins in November last year.
He represented his country at the 1994 World Cup, winning 14 caps.
He had a brief spell with Notts County in the mid-1990s and he also played in the USA, Spain, Germany and Israel.
Emenalo will work with new Chelsea manager Andre Villas-Boas.
Among Arnesen's responsibilities were transfer dealings and oversight of the academy.
