Wales coach Mike Ruddock knows his side face a stern test of their Grand Slam credentials against France in Paris this weekend.
While Wales have made a flying start to their RBS 6 Nations campaign, unbeaten rivals France have stuttered to wins against Scotland and England.
But French coach Bernard Laporte has recalled the likes of wing Aurelien Rougerie and centre Yannick Jauzion for a game that will see Les Bleus target a 10th successive victory in the RBS 6 Nations, stretching back to March 2003.
And Ruddock is under no illusions about what awaits Wales at a sold-out Stade de France.
"France have made changes, and brought in players they believe can fire the back-line a bit," he said.
"We believe this is the best selection we've seen so far from France in this season's tournament, and if they play to their potential, it will be a lot of hard work for us.
"But we are looking to go there, take the game to France and let them worry a little bit about us. I am encouraging the players to be bold and go out and play the game.
"We have played a style of rugby that is a bold style of rugby with a lot of attacking encouragement and skill from the players, so it's just about carrying on in the same vein."
Ruddock stressed the need to make an early impression on the French.
"We need to start well and get hold of the game," he said. "If we can do that, there is a bit of pressure on France.
"Even though they (France) won their first two games, they've got such high standards that people perhaps want to see total rugby from them as well.
"If we can take the game to them, then we could create that home disadvantage phenomenon, rather than the home advantage one they have at the moment."
Confidence is building in the Welsh squad, but Ruddock does not want his players to get carried away.
"At no time, within the camp, have we talked about winning championships, grand slams or triple crowns - we just have not done that," said Ruddock.
"It is going to be a difficult challenge for us on Saturday, but the boys are up for it.
"We believe in our style of rugby. There is a great team spirit - and we have got the players, we believe, if they put their game together to do very well in Paris.
"We try not to talk about the pressure; we just try and talk about the game plan and the way we want to approach the game.''
Andy Farrell admits the process of selecting England's 50-man training squad ahead of the World Cup was rigorous - but the backs and defence coach also revealed how tough it was to leave some stars out.
