Toby Flood is confident England can neutralise the potent threat of Dan Carter in Saturday's clash with New Zealand at Twickenham.
The All Blacks fly-half averages more points a game against England - 18.87 - than any of the other Six Nations or Tri-Nations teams.
"He is a huge part of what they do and what they are about. We need to manage him as well as possible," said Leicester fly-half Flood.
"Because he plays fly-half he is going to have a huge impact on the game, and because of that we need to be fully aware of the capability of not only what he has but also what he can do to bring his team-mates to the game.
"We have changed a couple of things around, not drastically, but in a fashion similar to the second Test against Australia in Sydney when we put pressure on Quade Cooper, and I think we will be looking to do something similar to stop him at source.
"You don't want to go overboard and concentrate on one person but you want to be able to adapt and change your game plan to look after individuals who may be a huge threat, and Dan and Quade are two of those guys who can run the show and cause you huge problems."
Flood has played just one full match for Leicester since damaging knee ligaments earlier in the season and England decided not to release him for Aviva Premiership duty last weekend.
With Jonny Wilkinson out of the Investec autumn series with shoulder damage, England manager Martin Johnson could not risk his first-choice fly-half.
Flood has started the last three England Tests, including the win in Sydney, and Johnson believes he is developing into a number 10 to rival the best in the world.
"Toby is getting better game by game," Johnson said. "He has missed quite a few in the last two years through injury but it is great to get him on the field and he is just going to grow and grow."
