Claudio Ranieri is set to become Nantes' new manager but requires special dispensation due to his age, according to L'Equipe.
A two-year contract has been agreed between Nantes and Ranieri, who guided Leicester to the Premier League title in 2015-16 only to be sacked the following season after a poor run of form, but because he is over 65 years of age special dispensation is needed from France's Professional Football League.
Nantes chairman Waldermar Kita said: "The league agrees, I believe that only the French Football Federation (FFF) with Mr. Domenech is blocking the file a little, I do not know why.
"What we are interested in is the experience as a footballer and coach, since we know very well that he has coached the biggest teams in Europe."
The job at the Ligue 1 club would be Ranieri's first since being dismissed by Leicester after a 2-1 loss at Sevilla in the Champions League, with the Foxes flirting with relegation from the Premier League throughout the year before pulling comfortably clear after the appointment of Craig Shakespeare.
Ranieri's role at Nantes will be the 17th managerial position of his career, having started at Vigor Lamezia, moving up through the leagues to sides like Napoli, Valencia and Atletico Madrid before a four-year stint at Chelsea.
After leaving the Blues, Ranieri had spells in Italy with Juventus, Roma and Inter Milan before leading Monaco back into France's top flight, leaving the club for the Greece national team after his contract was not renewed.
