The France boss has been summoned to an enquiry into the use of banned substances, with a particular emphasis on his time at Juventus in the 1990s
It was first reported earlier this month that the current France boss had been summoned to answer questions in relation to his time at Juventus as a player during the 1990s.
Most of those asked to provide evidence on alleged doping have done so before an open court, but Deschamps has been given special dispensation to testify in private.
Juve’s club doctor during his time at the club, Riccardo Agricola, was found guilty of sporting fraud in connection with the use of banned substances during the '90s in November 2004 but he was cleared on appeal a year later.
However, senator Jean-Jacques Lozach admitted that he is keen to hear Deschamps speak about his experiences in Turin.
"There is the story of the alleged doping at Juventus that interests us," he is quoted as saying by Tuttosport.
"We want to know if the fight against doping is a concern for the national team coach, but, above all, if the coach has proposals to make."
The 44-year-old called time on his playing career in 2001. He returned to Juve as coach in 2006.
