Fly-half Anthony Belleau, 21, will make his debut alongside scrum-half Antoine Dupont, 20 and with just three caps and none of those from the start, in one of the youngest ever half-back partnerships for Les Bleus.

"The half-backs are two young players. Given their performances for their clubs and Antoine's (for France) last season, when he was with us for the Six Nations and the tour (to South Africa in June), we decided we wanted to see what they could do at this level," said Noves.

Their selection is a surprise not least given that Belleau's Toulon team-mate Francois Trinh-Duc, a 30-year-old with 60 caps, is on the bench.

Belleau, however, has started seven of Toulon's nine Top 14 matches so far this season, having been the star of the club's semi-final victory over La Rochelle in May.

Dupont has been picked for his first start ahead of Bordeaux-Begles' Baptiste Serin, relegated to the bench after starting seven of France's eight matches this year.

However, one advantage is that Dupont and Belleau have already played together at under-20 level.

Back row Judicael Cancoriet, 21, and second row Paul Gabrillagues, 24, will also make their debuts, alongside Bastareaud's centre partner Geoffrey Doumayrou, 28.

The 29-year-old Bastareaud's last France appearance was in October 2015 in the humiliating 62-13 World Cup quarter-final thrashing at the hands of New Zealand.

"Looking at our opponents' potential, we've brought a bit of maturity to the midfield with Mathieu alongside Geoffrey, who's been showing his form and speed for some time," said Noves.

Doumayrou's selection is another surprise given Damian Penaud's form in South Africa in June, but the Clermont centre will start on the bench.

There are couple more surprises decisions. Teddy Thomas comes back into the side on the right wing for the first time since February 2016, picked for a sixth cap ahead of Hugo Bonneval and Gabriel Lacroix, and in the absence of injured Fijian-born pair Noa Nakaitaci and Virimi Vakatawa.

Nans Ducuing will earn just his third cap at full-back as South African-born Scott Spedding doesn't even make the bench.
