Ugo Mola will join Toulouse next season and looks set to succeed Guy Novès at the head of the team after more than two decades.
The former France full-back spent six seasons at Toulouse in the 1990s, and has coached at Castres, Brive and Albi, who he joined last season.
He is almost certain to replace Novès as head coach, with France's most successful club coach the strong favourite to take over the national job after the World Cup.
However, even if Novès does stay with Toulouse, Mola will still join according to Rugbyrama, and he is expected to work alongside current coaches William Servat and Jean-Baptiste Elissalde.
A fourth person could join the staff in the shape of Fabien Pelous, the former France skipper and current U20s coach who has been singled out as a potential director of rugby.
