Dave Ellis has been backed for a coaching role with England by Coventry director of rugby Phil Maynard.
Yorkshireman Ellis, 54, has quit after more than a decade as France's defensive coach, after helping them to the Rugby World Cup final.
And Maynard, who has booked Ellis for a couple of sessions at Coventry, said: "We'd be foolish not to use him.
"I've known Dave a long time. He's got a great pedigree," Maynard told BBC Coventry & Warwickshire.
"You've got to look at his background. He's had a great amount of success in the game. His stats will prove that.
"We've got a guy who's taken a team to the World Cup final and it would be daft not to use him in my view."
Ellis, who played rugby league for Castleford, Keighley, Doncaster and Batley, first made the switch to rugby union on the other side of the English Channel.
He coached at Racing Club de Paris and Bordeaux-Bègles before being invited by Bernard Laporte to join the France national set-up in 1999.
He has carried on working with France on a part-time basis ever since, while also taking on club jobs with Gloucester and London Irish, who he left in June to concentrate on the World Cup.
Now, while he awaits his next move, he has accepted Coventry's offer to come to the Butts Park Arena as Maynard attempts to build on their position of sixth in National League One.
"He just brings a different emphasis completely," said Maynard. "Discussing defence with him on another level is great, not only myself, but for the rest of the coaches and the team.
"You talk about the French and how they defend. They've got three of four different systems which they can change during the match and that's a high level."
