Mike Tindall believes Friday night's victory over Wales could go down as one of the seminal moments in England's development towards the World Cup and beyond.
England had not won at the Millennium Stadium since 2003 and ended that barren run with a 26-19 triumph, secured with two tries from Chris Ashton and Toby Flood's faultless kicking display.
"That was a great win. You hope it will be an important win in the team's development - but we mustn't get ahead of ourselves," said Tindall, who captained England for the first time on Friday.
The tournament is now set up perfectly for England to challenge for the RBS 6 Nations title, with successive home fixtures against Italy, France and Scotland before a trip to Ireland on the last weekend.
But Tindall warned England all their efforts in Cardiff will go to waste if they allow their standards to slip against the Azzurri on Saturday.
"We have to use the win as a stepping stone. Yes, there will be more expectation as we are at home but that comes from ourselves as well.
Italy won't come to Twickenham and lie down to let us win. We have to demand performances from ourselves.
"We don't want to win ugly and scrape through. We want to win with the brand of rugby we have put out there over the last 6-8 months.
If we do that we believe we will beat teams."
