The All Blacks will face their biggest Rugby World Cup challenge when they clash with France in the quarter final this weekend.

Flyhalf, Dan Carter says they continue to remain focused and will be in for a tough battle against France who has been often seen as their one and only true nemesis.

Carter says their physicality has been tested in most of their pool matches and they will also expect this against France.

He says playing France in Cardiff will be special for him as a player.

The All Blacks will take on France at 7am Sunday.

In the other quarters, South Africa will face Wales at 3am Sunday, Ireland will take on Argentina at 12am while Australia will take on Scotland at 3am Monday.
