Stuart Lancaster insists England need to continue to concentrate on their own game rather than worry about other fixtures after their 29-18 win over Wales set up a three-way tussle for the RBS 6 Nations title.
England secured their first triple crown in 11 years with a clincal display at Twickenham, with first-half tries from Danny Care and Luther Burrell proving the difference.
Their first win over Wales in four attempts leaves them level on six points with Ireland and France going into the final weekend of fixtures, with England's two rivals for the championship doing battle in Paris after Lancaster's men face Italy in Rome.
Ireland have a healthy points difference lead going into the deciding matches, but Lancaster has urged England not to worry about other factors.
England's last Triple Crown win came during a glorious 2003
"Ireland are a quality side," said Lancaster. "But France on their day at home, with something to play for - who knows?
"But we can't control that, we're first up. We've got a proud Italian side to play against who gave us a hard time two years ago and gave us a hard time last year at Twickenham.
"So we've got to get our heads right and do what we can do and control the controllables for us."
Lancaster had high praise for his England side, saying the victory was as impressive as their 13-10 defeat of Ireland a fortnight ago, especially coming a year after their 30-3 thumping at the Millennium stadium.
"It's right up there for me. It was a different type of game, the game against Ireland probably had a little bit more flow to it," he said.
"But because of the significance of the game last year and obviously the pressure on the boys to deliver, in light of the World Cup in a year and a half's time and playing at Twickenham, the boys wanted to win this game and I'm delighted for them that they did.
"If Luther had gone in for that try in the corner, I think it would have been reward for our counter-attacking and our intent to play.
"I think Leigh Halfpenny's goalkicking really kept the scoreline close for a long period of time.
"But overall, if you'd have said to me at the start of the day this was going to be the result I would have taken it, 100 per cent."
