England captain Chris Robshaw was in an understandably buoyant mood after his side secured the Triple Crown with a 29-18 win over Six Nations champions Wales at Twickenham on Sunday.
This victory, revenge for England's record 30-3 defeat by Wales in Cardiff last year that cost Robshaw's men the Grand Slam, left coach Stuart Lancaster's side with a chance of taking the title when the tournament concludes on Saturday.
Ireland and France, who face each other in Paris, and England are all level on six points following three wins from four matches.
However, Ireland are 49 points better off on points difference than second-placed England.
That means England have to hammer winless bottom of the table Italy in Rome and hope for a narrow French win (their points difference is a mere +3) at the Stade de France - or a draw - if they are to take the title.
"This gives us a shot going into next week," Robshaw told the BBC.
"We need a bit of luck with Ireland going to Paris."
Twickenham spectators have often been criticised for a failure to get behind England and creating an atmosphere more appropriate for a library.
However, a rousing rendition of the national anthem and a loud chorus of 'Swing Low, Sweet Chariot,' - the unofficial theme song of the England faithful - set the tone for a raucous effort by a crowd of more than 81,000.
"The crowd were absolutely outstanding today, and I've never heard the anthem so loud," said Robshaw, whose side outscored Wales two tries to nil, with scrum-half Danny Care and centre Luther Burrell both touching down in the first half.
"When you've got that passion and those fans behind you you can't let them down," the Harlequins flanker added after England secured a first Triple Crown since their World Cup-winning year of 2003.
"This team has grown, and we're extremely pleased with our performance.
All of Wales' points came courtesy of six penalties from ace goal-kicking full-back Leigh Halfpenny.
"The fact we gave Leigh Halfpenny 18 points off his boot is something we need to look at," said Robshaw.
"It could have been a better scoreline today but it was outstanding from the guys.
"It's a massive scalp - we all know what happened last year.
"We'd lost the last two times we'd played them and we needed some momentum back," insisted the back-row.
"We've now got ourselves back into contention, and we're ticking along.
"But it's a massive ask next week. We have to just focus on our own game and can't focus on points."
Italy have lost all four of their matches this Six Nations and went down 46-7 to Ireland in Dublin this weekend.
The Azzurri have never beaten England but Robshaw, looking ahead to next week's match at Rome's Olympic Stadium, said: "We've had some difficult fixtures against Italy - we've got a day less to recover and we have to make sure we're fresh.
"Emotionally, too, we have to make sure we're on top of it."
