(CNN) -- All Blacks captain Richie McCaw is warning his side against complacency as they go into Sunday's Rugby World Cup final against France as odds-on favorites to lift the William Webb Ellis trophy. 

While hosts New Zealand have enjoyed a relatively smooth and unbeaten passage to the finale of the global showpiece at Eden Park, France have been beaten twice and failed to hit their top form. 

But McCaw, who was left in tears as the All Blacks stumbled to a 20-18 quarterfinal defeat to the French in the 2007 World Cup, said Saturday that negative media coverage had given Les Bleus extra motivation to spring another upset. 

"I've got no doubt the French are going to play their best game and you blokes have loaded the gun for them," he told gathered reporters at the official press conference. 

"They've got players who've been around for a long time and they understand what it takes to win Test matches." 

And as to France's indifferent form, including a 37-17 loss to his team and a dismal defeat against Tonga in the pool stages, McCaw believes it counts for nothing. 

"In a final it's not about who 'deserves' what," said McCaw. 

"It's about who goes and plays the best rugby on that stage, in this game, that's what we've got to do." 

The All Blacks, the traditional powerhouses of international rugby, are searching for only a second World Cup triumph, their only title coming in the inaugural tournament in 1987 when they beat France in the final in Auckland.
