Winger Yoann Huget says France are not good enough to take Scotland lightly at Murrayfield on Saturday.
Philippe Saint-Andre's men go into the match in title contention having beaten England and Italy, but the manner of their defeat to Wales caused a stir in France.
Saint-Andre dropped number eight Louis Picamoles for sarcastically applauding referee Alain Rolland after being sin-binned at the Millennium Stadium.
The coach has 10 players unavailable because of injury or suspension and Saint-Andre made seven changes to his team from that which was crushed 27-6 in Cardiff, their heaviest defeat to the Welsh since 1950.
But Toulouse flyer Huget - who was denied a second-half score at the Millennium Stadium which may have made a difference - claims his side will suffer yet more pain if they fail to treat the Scots seriously.
Under no illusions
Huget told L'Equipe: "We can't pretend to ourselves that today, we're better than Scotland. We will start well by taking our kicking game seriously, and then we will see.
"But in any case, it's not a good idea to start taking risky shots in the opening minutes at a fiery Murrayfield.
"We are working hard and we have things in place, but we haven't made them work yet. When there is a delay in a ruck, it's better that our full-back Brice Dulin gets the ball back behind an organised line.
"We coped better against England - we were in a rush against Wales - and the centres took part in recovering the ball.
"But it shouldn't be the case that a single grain of sand in the wheels stops us from getting going. We need to get the ball as far forward as quickly as possible with fast accurate passes."
