Head coach Bernard Laporte believes his France team will pay a heavy price if they underestimate a new-look England side at Twickenham on Sunday.
Les Bleus, unbeaten in this year's RBS 6 Nations Championship, are favourites to beat the world champions, who have made significant changes - both in personnel and positional - to the side that was savaged by Ireland at Croke Park a fortnight ago.
Laporte knows England's newcomers will be desperate to make an impression in front of their own crowd, especially with the World Cup just around the corner.
'It doesn't matter about the composition of their team,' he said. 'At Twickenham, there will be 15 Englishmen facing us who would like to beat us.
'And even if there is less euphoria around them than four years ago, I am not forgetting that there will be eight new players who will be very keen to show that they deserve to play in the World Cup.
'For us, the important thing will be to put in the necessary work and especially to perform in every department.
'That has not been the case since the start of the tournament.'
With only a home match against Scotland left after this weekend, a win for France at Twickenham will go a long way to securing a fourth RBS 6 Nations title - and a third Grand Slam - in six years.
Laporte does not believe it is his place to talk up the prospect of a clean sweep of victories in the tournament.
'I haven't spoken about it for one second to the players,' he added. 'And I will never speak to them about it.
'What I want is to win the game. The Grand Slam, it is their story. I don't want the glory through the sweat of others.
'It is for them to write a beautiful page in the history of French rugby.'
