It would be natural to expect the French to be a tougher side to beat in Paris than they were in New Zealand. They rarely lose Six Nations games in Paris and even if they occasionally lack accuracy at home, they live off emotion and passion and deliver greater intensity.
"We saw in June how tough these matches are. When you come to France they just seem to come up a couple of cogs from that. You have got two nations with a great history against each other and there is a lot of respect for how they play from us."
Yet, despite France's reputation as a better side at home, the All Blacks have an impressive record in Paris. They haven't lost in the French capital since 1973 and have won 10 of their 13 encounters in France. Their last defeat here came in Marseilles 13 years ago and in 2004 and 2006, the All Blacks romped to record victories.
Clearly, being in France does something to lift the All Blacks as much as it does the home side - something they will be hoping for again on Saturday.
"We want to be aggressive," says Foster. "We want to be bold in terms of how we play. I am not sure what being bold means for them - I would imagine doing what they do well. They have a physical pack - the set-piece and breakdown are the core parts of their game."
