But despite rumours of a rift in the camp, Nallet - who will start in the second row on Saturday - insists his side are ready to take on an England side who have knocked them out of the last two World Cups.
"We still have a right to believe. We're still here. We must stop asking questions, stop saying that training's too long, stop saying that things aren't going well," said Nallet, who captained the side for the first two years of Marc Lièvremont's tumultuous reign.
"We live together, we like each other, and maybe we didn't want to be aggressive toward one another. We weren't aggressive on the field, either.
"There's a lot of motivation, everyone wants to try to save our honour in this match.
"Everyone wanted to say 'I got it wrong' [after the Tonga defeat]. Since we've arrived in New Zealand we haven't had the mentality to conquer anything whatsoever.
"Everyone wanted to take their share of the blame and tell the others they will be ready this weekend."
