Didier Retière is also currently the technical director of the French federation.
The second son of Ireland international Trevor Brennan will be making his mark on the France u20 squad.
Second rower Joshua Brennan follows older brother Daniel into the France u20s squad having also won the Espoirs Championship with Toulouse, their first win in the competition in 18 years.
Older brother Dan played in the same u20s squad as Romain Ntamack. He has joined Brive ahead of the 2020/21 Top 14 season.
Looking to follow in his brother's footsteps, Theo Ntamack has been included in the France u20 side.
The Toulouse back-rower, who can also play lock, follows his brother in being selected for the u20s side having shone in the youth ranks with Toulouse.
Also the son of France and Toulouse great Emile Ntamack, Theo has a reputation to live up to but has got off to a bright start winning the Espoirs Championship title with Toulouse.
There is a mouth-watering possibility of seeing a sibling 9 & 10 combination for Italy in the years to come as just a year after Paolo Garbisi pulled the strings for the Azzurrini, it will be little brother Alessandro making his steps towards a top flight career at scrum-half.
Back rower Lorenzo Cannone follows his second-row brother Niccolò in representing the Italian u20s.

Cameron played u20s level for England before debuting for Scotland during the 2021 Six Nations against England.
Byran Redpath and Gregor Townsend formed a successful halfback pairing in the mid-1990s and early 2000s.
Their sons Murray Redpath and Christian Townsend both play in the same positions their fathers did, scrum-half and flyhalf respectively, creating the intriguing possibility of their forming a halfback partnership as their dads did.
“Christian studies the game well. He has a lovely pass on him and he has really grown into his role these last couple of months. He takes the ball to the line well,” said Scotland U20s coach Sean Lineen.
“He is a heads-up rugby player.”
