It's the match that England captain Martin Corry has picked out as the "defining moment" of his side's World Cup: England v South Africa.
We get under way at 2000 BST in Paris, and the outcome of the game will have major repercusions for both sides.
The defending champions have had a week to forget. Some might say they've had a four years to forget, but that's by the by now.
If England cam somehow summon up the kind of performance that we hear they produce at the drop of a hat in training, then maybe they could upset the odds of 6-1 on offer against them succeeding.
If they don't and the Springboks live up to the 10-1 on odds that bookmakers are so generously offering, then England could be in for a long, long night.
