All Blacks captain Richie McCaw is targeting his third Grand Slam when New Zealand take on Wales at the Millennium Stadium on Saturday.
The brilliant openside has played a key part his country’s last two all-conquering tours to Britain and Ireland in 2005 and 2008.
Now the fearless flanker is lining up a historic third by leading his side to victory over a Wales side who drew with Fiji last time out.
Wales have not beaten the All Blacks in 57 years since legendary Lion Bleddyn Williams led them to a famous victory back in 1953.
Warren Gatland’s men are yet to win this autumn, leaving the All Blacks as heavy favourites, but McCaw has admitted he expects a hard fought encounter despite history and form being on his team’s side.
"Winning Grand Slams are not easy at all because you have to get yourself up every week to perform,” said McCaw, who was a central figure when the All Blacks beat the Lions in 2005.
"You saw the Irish were a different team to how they played against Samoa and I expect the Welsh to be exactly the same after their draw against Fiji.
"We don’t want to get too ahead of ourselves. But the boys are motivated for the game which you would expect."
Triple Lions tourist Martyn Williams is set to wear the number seven shirt for Wales as he edges closer to 100 Welsh caps.
The 2001, 2005 and 2009 Lion has currently made 98 appearances for his country, as well as four for Britain and Ireland’s elite.
And McCaw, who is only just short of the magical 100-mark himself, is full of praise for Williams’ achievements.
"It is a pretty special achievement and he deserves it. He's a pretty good player and works well when he gets his hands on the ball,” added McCaw.
"I always have a good challenge against him and he's a hell of a nice guy. I always enjoy it."
