Benjamin Boyet fears nerves may get the better of him if he is thrown on as a substitute in Sunday's RBS 6 Nations clash with Scotland at Murrayfield.
The Bourgoin fly-half has been selected on the bench for the clash with the Scots, but is set to play some part with first-choice playmaker Frederic Michalak having only recently shaken off a groin injury.
With coach Bernard Laporte and manager Jo Maso looking to find an understudy for Michalak ahead of the 2007 World Cup, Boyet knows the pressure will be on him if he does come on as a replacement.
And the 26-year-old hopes he is able to adjust to Les Bleus' style of play if and when his time comes.
"It is going to be a bit delicate because the French team has a special system and I'll have to adapt," he said.
"I am apprehensive because I don't have my bearings with Les Bleus. I am worried I could have problems finding my feet. I don't want to disturb nor disappoint the players who have been playing for France for a while."
France go into the RBS 6 Nations on the back of some superb performances in the autumn internationals, when they defeated Australia, Canada, Tonga and South Africa.
Boyet, who looks to be competing with Yann Delaigue for the role as Michalak's understudy, hopes Les Bleus can build on these displays against the Scots.
"I've been concentrating extremely hard all week (in training)," he said. "I listened a lot, especially what was said about the November matches. I will use our displays back then as my inspiration."
On his rivalry with Delaigue, Boyet added: "Laporte's been looking for another number 10 for a while. There is Fred and Yann, and now me.
"My destiny is in my hands. We will see what happens in the next few matches but I want to show what I am capable of and that I deserve to be here."
Boyet's stock has risen thanks to a string of impressive showings for European Cup entrants Bourgoin this season, leading many observers to compare him to the mercurial Michalak.
Michalak, 23, may have started his international career at a much earlier stage but Boyet believes there is still time for him to make an impression for his country.
"Everyone has his own destiny in sport," he said. "I can now express my game at the age of 26, which means I needed time.
"It's good for Fred that he could do it earlier. The reason why I was a bit late is because it took me time to understand I had to work hard. At 23, I was clearly working less.
"The consistency and regularity of selection I have had at Bourgoin has helped me a lot.
"In the past two years, we've been regular qualifiers for the semi-finals of the competitions we've entered.
"The team has a lot of quality and their high level of performances have catapulted me to where I am now."
