New Zealand's Dan Carter will be the talisman against England on Saturday and here his fellow fly-halves discuss how good he actually is.
Toby Flood - England
He's got the complete game, really. His understanding of the game is as good as it gets. As a No 10, it is so important to be able to understand the flow and feel of a game around you and I think he's got that, which means he makes good decisions for his team.
Dan is one of those guys who seems to drift in and out of games, but he's not, he's just getting an appreciation of what is going on, then he knows when to strike.
He's a constant running threat and he's obviously got an outstanding kicking game too.
I would think he's got another World Cup in him. As a 10 you get whacked around a bit so it takes its toll physically, but he has got sabbaticals so he will look after himself.
Joel Stransky - South Africa (1995 World Cup winner)
The more Dan has played the more he has matured. He always seems to have time on the ball - a sign of the great players.
Dan always seems to have this massive calming influence on the All Blacks, though I think he would be the first to say that he's not been at his best this year. I think the injuries have disrupted his play and he's been in and out of form.
The All Blacks have not been so dependent on him since injury cut short his 2011 World Cup and they are learning to play without him. But the way they produce fly-halves - it's like a sausage factory.
However, Dan is still their main man and they will be looking to him this Saturday against England at Twickenham.
Grant Fox - New Zealand (1987 World Cup winner)
He is a very special player and a good man. He's a great tactician, he's got a good kicking game, he's very strong defensively, he's got a good running game and he passes the ball well.
Daniel is also a great goal-kicker and holds the world points record by some margin. I'm loath to talk about whether he is the best No 10 in history as it's very hard to compare era to era.
But he has been the most dominant player in his position in the last 20 years and he has the full range of skills. It is hard to pinpoint a weakness in Daniel's game. That night against the Lions in Wellington in 2005, he said: 'I am now a world-class player.'
