France captain Fabien Pelous is wary of the threat presented by Wales as the two teams prepare to clash at the Stade de France on Saturday.
But the 32-year-old lock is unconcerned at the lack of attacking penetration shown by Les Bleus so far in the RBS 6 Nations that has seen them rack up just 34 points from victories over Scotland and England, and has declared that the team are in a rebuilding phase ahead of the next World Cup.
"Wales is a very good opponent and the Welsh players are efficient on a wide pitch," Pelous told L'Equipe.
"France's offensive game is not at the right place yet and we need more time. Our team is young, we are trying to build something together.
"The 2005 tournament is similar to 2001 when we started to build the World Cup squad. Give us time but I would like to say, Wales inspire fear in me."
Both France and Wales are unbeaten in the tournament and victory for either side would see them take outright leadership ahead of Ireland's clash with England at Lansdowne Road on Sunday.
Meanwhile, flanker Serge Betsen is confident of meeting the Welsh after making good progress from his thigh injury.
The Biarritz back-row forward, who has won 45 caps and is one of coach Bernard Laporte's key players, sustained the problem during the 18-17 victory over England but hopes to be fit.
"I ran for 20 minutes last Saturday and I am optimistic. Since my injury at Twickenham, my rehabilitation was based on physiotherapy," Betsen said.
"I am going to see the staff at Marcoussis (National Rugby Centre) to be sure but I feel good, I do not have any pain."
Mako Vunipola may be his rival for a starting spot in England's front row but Joe Marler is ecstatic to have his fellow loosehead back in the international fold - claiming it will spur him on to even greater heights.
