France flanker Julien Bonnaire has warned his team-mates not to underestimate Samoa at the Stade de France.

Les Bleus host the South Sea Islanders in the second Autumn Test full of confidence following a superb victory over South Africa.

However, Bonnaire has urged his side not to feel they can let their game drop against Samoa, who slipped to a narrow defeat in Wales last week.

"At the end of the day we're facing it like any other game," he told L'Equipe. "As usual we have to be performing to succeed in imposing ourselves.

"But it is a match to take seriously, we saw what they did against the Welsh. For us, it is about continuing to put our game out there.

"It is important to get a run of good results. It matters little what team you are up against, we have to manage to be consistent and impose our game.

"If we remain efficient, there will be the victory at the end."

France coach Marc Lievremont has faced criticism in some quarters for making 12 changes to the lineup that defeated the world champions.

Bayonne wing Benjamin Fall and Clermont flanker Alexandre Lapandry benefit from the changes and the 20-year-olds will make their debuts tomorrow.

Bonnaire admits the shake-up has made things more difficult for France.

He said: "We have still had a week to work on it and we did find ourselves at the same level as the others last week.

"But even though we participated in training session, we still had to start everything all over again and find an understanding in passing and in the scrum."

France have been hit by injuries this week.

Louis Picamoles was ruled out of the match after picking up a knee injury in training and the 23-year-old will be replaced at number eight by Bonnaire.

Captain Thierry Dusautoir will move into Bonnaire's position to earn his 27th cap while Lievremont has called up Bayonne's Julien Puricelli who will start from the substitutes' bench.

Samoa's Cencus Johnston is fully aware of how much victory would mean to the islanders and insists his side, who sit six places below France in the world rankings, are in with a chance.

"In Samoa rugby is a religion," said the Stade Toulousain prop. "It's really what matters most.

"There, you play with what you find, a bottle, a pair of socks.

"There is a group which is now beginning to gel and several individuals which can influence the match.

"We will prepare ourselves well so we can challenge the French."
