Coach Clive Woodward has warned that England will have to be at their best if they are to avoid an upset against a Fiji side he believes were unlucky not to have beaten France.
Twenty-fours after watching his side hit three figures against Tonga, Woodward flew to France to watch the Fijians slip to a narrow and controversial defeat, 28-19, to the off-form northern hemisphere giants.
The England coach returned with a warning to his players that they will have to be at their sharpest mentally - and at their hardest physically - to win today and secure a quarter-final berth against world champions South Africa in Paris.
"I was in Toulouse and I thought France were lucky to beat Fiji. I don't want us needing to rely on luck," said Woodward. "We must produce our top form, which is why I have picked my best 22 players. There is always a little fall-back in the pool stages, the chance of another game to make amends if you play poorly. But there are no second chances when you reach this stage of the tournament. It's a play-off. The winners will go to Paris for a quarter-final crack at reigning world champions South Africa. But the losers go nowhere.
"Fiji are much stronger than Tonga. They are more street-wise and physically stronger in the scrum. There was a lot of intensity in their play against France. They look to be a well-coached, well-drilled side. I'm not underestimating Fiji at all."
Fiji, though, have injury problems and will be without former Australian flanker Ilie Tabua. There are also doubts over centre Waisake Sotutu and out-half Nicky Little, who has an ankle strain.
"Tabua's body is broken," said Fiji coach Brad Johnstone, who is relishing the challenge of facing England.
"It will be a great occasion for us to walk out at Twickenham. You have 15 guys with laptops and fast cars against 15 guys who have only rugby balls."
Woodward has made seven changes - six personnel and one positional - after the 101-10 rout of Tonga.
Bath centre Jeremy Guscott was not considered due to a groin injury while prop Phil Vickery and lock Danny Grewcock are rested following their Pool B rigours which saw England finish second behind New Zealand.
There are first World Cup 99 starts for wing Nick Beal, centre Mike Catt and prop Darren Garforth, out-half Jonny Wilkinson returns instead of Paul Grayson and loose-head prop Jason Leonard is back for Graham Rowntree.
Neil Back takes over from Richard Hill in the back row and talented young Wasps forward Joe Worsley keeps his place.
Versatile Austin Healey moves from wing to scrum-half with first-choice number nine Matt Dawson, who suffered a chest injury during the Tonga match, among England's seven replacements.
Healey, who last wore the number nine jersey in a Test against Wales more than two years and 20 caps ago, will be expected to continue the roving role that has made him one of England's biggest World Cup success stories with an ability to pop up almost anywhere behind the scrum, running devastating attacking angles.
