Morgan Parra can spark a revolution among France's forwards tomorrow night to inflict a second quarter-final defeat on New Zealand in Cardiff in eight years, according to Philippe Saint-Andre.
France boss Saint-Andre defended dropping trusted half-back Sebastien Tillous-Borde in favour of Parra by accepting his pack need to be bossed about after last Sunday's feeble showing in 24-9 defeat to Ireland.
Les Bleus stunned New Zealand 20-18 in Cardiff in 2007, with Saint-Andre admitting only a return to classic French free-running rugby will afford the chance of a repeat.
Saint-Andre confirmed he had promoted Alexandre Dumoulin ahead of Mathieu Bastareaud into the centres as part of that bid to boost his side's front-foot fluency.
"If there's not an uprising for this match, you must change sport," said Saint-Andre.
"If we want to beat New Zealand, we will have to play the French way.
"We're getting ready for a massive battle.
"We know we'll have to improve our up-front game and take more individual initiatives.
"It hasn't been a mistake to back Tillous-Borde so far.
"But Parra is a very strong competitor, he's having a great World Cup and I've decided to start him because we all know his leadership qualities when it comes to the forwards.
"Alexandre Dumoulin is a player who is really very capable of keeping the ball alive."
