Rowntree spent this week drumming into his men the need to reproduce the same intensity of performance that rocked the world champions at Twickenham just two months ago.
He said: "I am pleased how the last year has gone but I want more. We are nowhere near where we can be and no-one knows that more than us. We have spoken a lot this week about recreating the intensity we showed against New Zealand. That has to be our benchmark going forward."
He continued: "We know where we are in terms of our group, our experience and what we have to get better at. That's what drives us on, that (quest for) perfection."
Having achieved such a remarkable high against the All Blacks, England are now seeking a consistency that will turn them from a side capable of beating anyone into "a champion team".
"We have got a good culture and one of our bedrock statements is we have to be hard to beat," Rowntree said.
"We will challenge teams in every area of the field.
"The challenge for us now is about dealing with the expectancy and backing up our performances.
"There is nothing more daunting to me than a team coming here with nothing to lose.
"They are always tight games given the competition between the two countries. I am on edge about the game."
