Mike Ruddock has described English attempts to install Wales as favourites for Saturday's Six Nations Championship showdown as "bizarre".
Wales, who set off along the M4 today as reigning champions, have not beaten England at Twickenham since their Triple Crown season of 1988.
Coach Ruddock has also had to contend with a significant injury list while suspension rules out Gavin Henson, Dafydd Jones and Ian Evans.
Ruddock's England counterpart Andy Robinson has described the Six Nations opener as his team's most important game since the 2003 World Cup triumph. But the Welsh camp have drawn their own conclusions about what is potentially a season-defining game.
Ruddock said: "We are expecting England to be really fired up.
"I think they have gone on record as saying this is the most important game for them since the World Cup.
"They have also stated that we are favourites, which we find quite bizarre because our record at Twickenham is not great and because of a number of other factors, including injuries, that have happened to us.
"It looks like there is a bit of pressure on England - they don't want to lose at home and they don't want to lose against us.
"They are very fearful of that, and they are trying to put the pressure back on us. But, to be honest, we are quite relaxed about it."
Ruddock has lost injured grand slam heroes Ryan Jones, Tom Shanklin, Brent Cockbain and Kevin Morgan but remains upbeat as Wales try to end 18 years of failure at English headquarters.
He said: "As coaches and players, we try to do the best we can. We can't predict the future, we can't look into a crystal ball and say we are going to win three games out of four or we are going to win a grand slam.
"All we know is we will try to get the players to relax and play to the best of their ability. We took it game by game last year and it worked for us, and that is what we will do again this year."
Wales have suffered some fearful beatings at Twickenham since 1998, conceding 35 points a time in eight successive defeats. The popular perception is that England could again make life tough by dominating through their heavyweight pack.
The potential for English dominance up front is not lost on Ruddock who remembers the Twickenham clash two years ago when Wales struggled to gain forward parity.
He said: "We managed to win only 55 per cent of our line-out possession on our own ball, and we pretty much got steamrollered in the scrum and they finished us off when Julian White came on from the bench.
"It really made things difficult but we were right in the game for 70 minutes or so even though we struggled for possession."
Wales are confident that if they can secure enough possession for their backs they possess the firepower to cause England problems.
Ruddock also has no qualms about the appointment of New Zealander Paul Honiss as referee, after fierce criticism of him following his handling of last Saturday's Premiership clash between Leicester and Sale Sharks.
He said: "Paul Honiss refereed us against France in Paris last season and we have also looked at some of the autumn games such as France against Australia that he refereed so we have got an angle on what we think he wants to see on the rugby field in terms of the interpretation of the laws.
"He is a fine referee who is respected worldwide but, regardless of who the referee is, my message has always been the same to the players. I was very impressed with him in our game against France last season."
Wales centre Ceri Sweeney had to withdraw after pulling up in training yesterday with a groin injury. Cardiff fly-half Nicky Robinson will take Sweeney's place on the bench.
