Citroen World Rally Championship team principal Yves Matton is in discussion with the FIA to replace Jarmo Mahonen as head of the governing body's rally department.
Matton has declined to comment on speculation he will leave Citroen but sources at the FIA have admitted it is chasing Matton.
There has been no official comment from the FIA.
Mahonen announced late last year that he would be standing down at the end of the season and the FIA originally sought Volkswagen Motorsport director Sven Smeets for the job.
Smeets told Motorsport.com he was flattered, but his priority remained returning the VW to factory-level motorsport.
The FIA had hoped to have Mahonen's replacement in position for the start of the year, but that process has been slowed in recent months and now looks to hinge on a deal with Matton and some sort of understanding to extricate him from his Citroen contract.
A source told Motorsport.com: "It looks like things are finally moving. It's hard to replace a guy like Jarmo, but there should be some news soon."
There has been further speculation that Matton's position at Citroen could be taken by his opposite number at Peugeot, Bruno Famin.
Famin is currently in South America, guiding Peugeot's final Dakar assault with the 3008 DKR.
