Raphael Ibanez paid tribute to France's unbreakable belief after they kept their hopes of Six Nations glory alive with a last-gasp win over Wales.
French hopes of a comeback victory appeared to have been dashed when they had lock Paul Willemse sent off and a try chalked off in one fell swoop by the TMO with 67 minutes gone.
That left Fabien Galthie's side a man down and 10 points behind a Wales side who looked destined to complete a Grand Slam in Paris.
However, the visitors lost both Taulupe Faletau and Liam Williams to the sin bin in quick succession before Charles Ollivon crossed the line and Romain Ntamack converted to reduce the deficit to three.
And Brice Dulin broke Welsh hearts in the 82nd minute as he made the hosts' extra man tell, touching down after the ball had been worked quickly to the left.
Reflecting on the drama, team manager Ibanez told the BBC: "It was an incredible finish. Mixed emotions. It was a fantastic battle for the whole game and obviously, we got the win but it's just incredible for the boys, a massive effort.
"At times during the game, we were under massive pressure. Wales scored their opportunities, we missed a few opportunities, made a few mistakes during the game.
"But in the end what really matters in sport is just to believe and that's what the boys did until the end thanks to magnificent tries."
Asked if he thought France's hopes of winning had gone when Willemse was dismissed, Ibanez heaped further praise on the players' character.
He added: "Yeah, but you still have to believe in yourself when you start the game of rugby.
"The intensity, the battle was just immense. Credit to Wales, they fought until the end, but the boys showed so much character.
"I think, in the end, it's going to give a lot of confidence to the boys for the next game."
That next game pits France against Scotland at Stade de France on Friday, with the hosts knowing that a bonus-point win by a margin of 21 points would see them crowned champions.
On refocusing for that challenge, Ibanez said: "It's pretty simple. We're still in it and the next game will define our Six Nations.
"We still have a chance to win the Six Nations so let's celebrate tonight in the changing room and then tomorrow we are going to regroup and work hard as we did this week."
