Andy Farrell is confident England are ready for their key Six Nations clash with Ireland in Dublin on Sunday having prepared with the intensity required for a match-up of such history, rivalry and quality.
England have not won a Six Nations match on Irish soil in a decade and Farrell rates the challenge facing Stuart Lancaster's side is among the biggest in world rugby.
"This game is as big as any game you get in world rugby," said Farrell, the England assistant coach.
"Coming to Dublin is as big a challenge as anywhere really, because of the history and rivalry and just how good the two teams are. It is a challenge we are definitely ready for and up for."
Two years ago England's Grand Slam hopes were destroyed when Martin Johnson's team lost in Ireland.
With all the hype surrounding the game, England decided on a low-key build-up and they ended up being blown away by Ireland's heightened levels of ferocity and intensity.
It was a mistake which Farrell is adamant England will not repeat on Sunday.
"Graham Rowntree [Farrell's fellow assistant coach] was part of that game two years ago and on reflection they got the preparation wrong, with it being too low key," Farrell said.
"Our preparation has been intense and we feel that is appropriate. We are really well prepared."
Despite heading into this year's Six Nations under the radar to some extent, Ireland proved their quality and commitment with a superb first half against Wales which set up a 30-22 victory over defending champions Wales in Cardiff.
"We know the passion there is going to be and the intensity Irish sides bring," said England captain Chris Robshaw.
"We are under no illusions exactly how hard and how intense it is going to be but these are the games you want to play. As a squad, we have had spikes of intensity all week."
