England captain Chris Robshaw hopes to treat the Twickenham faithful to a "much improved" attacking game against Wales on Saturday.
England won their first two Six Nations matches but without setting the tournament alight with their play.
"We know our performances weren't perfect but we've really worked on that," said flanker Robshaw.
"We always knew going up to Scotland and away to Rome that it was all about getting the win, first and foremost."
England have narrowly beaten Scotland and Italy so far under the stewardship of interim coach Stuart Lancaster but only managed two tries in the process - both charge-down scores by fly-half Charlie Hodgson, who misses the Wales game through injury.
Most of England's points have come from the boot of Owen Farrell, who starts his first international game at fly-half against the Welsh.
But England assistant coach Andy Farrell, Owen's father, said he sensed "something different in the air."
"The training's been very upbeat, you can tell the guys are revving up for a big weekend," said Farrell.
Farrell added that returning centre Manu Tuilagi, who missed England's first two games with a hamstring injury, is desperate to make an impression.
"He's super keen to get back to playing. He's had a bit of a stop-start season as far as injuries are concerned, and for any young lad I think that's very frustrating.
"He's had two games [for Leicester] to get his match fitness back [and] he needed those two games to get his confidence back.
"In Test match football you need to be fit and confident that you can perform in the arena, and Manu is certainly ready for that step now."
Farrell also thanked ex-Great Britain Rugby League team-mate Jonathan Davies for providing England's team talk after he declared they would be "smashed" by Wales.
He said: "People are calling us underdogs and it adds spice to the game.
"I sent [Davies] a text to thank him - I said it was brilliant news!
"Everybody is a competitive beast. Of course pride comes into it. Everybody wants to prove people wrong.
"There is a sense of excitement that we can and that is a big motivation for us going into the game.
"Wales have been playing very well of late. They are a good side and it will be a challenge for us - a new side coming home for the first time in the Six Nations.
"But we have been pretty good at meeting challenges head on so far."
