"I'm sure H wasn't too happy he said that because he's trying to paint a picture that they will have to play the best game they've ever played in their life. That's his way of motivating his team."
Hansen feels the excitement generated in the media and other external sources about the All Blacks' performance in the 62-13 thrashing of France could also serve to knock his team off their game.
Springboks bring out the beast
"The hardest thing this week in preparation is coming off the back of such a great win because externally everybody has got a little carried away with themselves and ... have made some outrageous statements.
"Internally there's an emotional high that comes from playing like that and it's really important to get a full stop as early as possible. You've got to enjoy that moment - you can't hide from it, but you've got to put a full stop on it otherwise you don't go great-to-great, you go great-to-struggling.
Springboks want to rip our heads off
"We've acknowledged that to ourselves and we believe we've done that.
"I don't think we've played our best rugby. We went through the pool stages and you blokes [media] were telling us we were struggling which I really appreciated because it kept us on edge, and then we played really well. We played to standard we expect to play at, and there were a number of reasons why we did that - it was life or death, you either win or you go home."
