Martin Johnson insisted England must treat their Rugby World Cup showdown with Scotland as a do-or-die clash, despite the fact a losing bonus point should be enough to book a quarter-final place.
England are unbeaten on top of Pool B and can afford to lose to Scotland by fewer than eight points on Saturday and still progress to the last eight.
But that is not Johnson's mindset and England will be chasing the victory at Eden Park.
Johnson has made three changes from last weekend's 67-3 victory over Romania, with Delon Armitage replacing Mark Cueto on the wing while lock Courtney Lawes and prop Matt Stevens both return.
"It's knockout rugby," said Johnson.
"We have to win, they have to win. We are not talking about getting a losing bonus point. We want to go and win the game."
Neither Scotland nor England have ever failed to qualify for the knockout stages of the World Cup.
Scotland are up against it following their 13-12 defeat to Argentina and must beat England by the biggest margin in 25 years to stand any realistic chance of progressing.
"They are potentially dangerous, potentially vulnerable. It is how they handle it," said Johnson.
"Their frustration their fury, whatever they have talked about this week, they have to turn that into a performance.
"We have to turn where we are into a performance.
"This is the oldest international in the world, there is a lot of history there. That is all for the build-up and the exterior.
"It is about us playing well. You have got to handle the pressure, handle the expectation, handle the spotlight and go out and play.
"If we do that we will put ourselves in a good place."
Armitage takes over from Cueto, who sparked England's victory over Romania with a quick-fire hat-trick on his comeback from injury.
Armitage missed England's RBS 6 Nations campaign after being suspended for eight weeks following a run-in with an anti-doping official.
But Johnson has been impressed with his form and dedication - and he gets his chance against Scotland with Cueto deemed to still not be 100% match fit after a back injury.
"Delon has played very well, we are very comfortable with him playing there and Mark has had limited game time since he has been here," said Johnson.
"He has played very well. I said all the way through that if Delon is in good form he is a Test match player.
"He wasn't available to us in the Six Nations but he has come back from that and has worked very hard all the way through.
"I said if he is playing well and doing everything right he will get a shot and put pressure on the guys in the top three.
"The injury with Mark has been a factor with that and he is probably one game short of being right back where he could be."
