Sean Fitzpatrick has warned England that Daniel Carter is fully charged to prove he's still the world's best No.10.
All Blacks legend Fitzpatrick also claims the New Zealand public will be demanding English blood having not yet recovered from the World Cup heartbreak.
Speaking to promote the exclusively live and high definition coverage of New Zealand v England next Saturday, at 8am on Sky Sports 1/HD1, said: "In my mind, Carter is playing as well as ever.
"He's had a six week break after the Super 14s and looking in top shape.
"I expect to see him on top of his game against England and make his usual big impact on both Tests. When he's firing there is still no other No.10 to match him.

"England will know all about what he can do, but knowing is one thing and stopping him is another."
He added: "I was very impressed with the high standard and intensity shown by all the clubs in the Guinness Premiership and the Heineken Cup.
"The English guys have had the advantage of going head to head with so many of the top international stars who now litter the Northern Hemisphere.
"The pressure is on Graham Henry after the World Cup failure and the public demand results."
