TWICKENHAM, London -- From Will Carling through Gordon D'Arcy, Bob Dwyer and Jonathan Kaplan to Danny Cipriani, it feels like just about anyone who has been involved in an England international game has had their say on where Saturday's match against Australia at Twickenham will be decided. 

England have tried to stay as oblivious as possible to the outside barbs at their Rugby World Cup prospects. They attempt to live an almost hermit-like existence in their Pennyhill Park base but in the age of omnipresent social media, they will be blindingly aware of the magnitude and expectation of their match against the Wallabies. Put simply: lose and they are out of their home tournament with a pool match still to play.

Their responses to the criticism have largely been typical of the Lancaster era: humble, personable and respectful. But even Lancaster -- who was hugely impressive when addressing the media at length on Thursday -- let his guard down a couple of times to fire a warning shot at the Wallabies loose-head, Scott Sio. Even then his caution for Sio that an extra ten Joe Launchbury kilogrammes will be behind Dan Cole came with a smile.

Alongside the odd shot from Lancaster has been an admission this week that the fortunes of this World Cup campaign will be laid at his door. Lose and England will be consigned to the same ignominy that has befallen the nation's football and cricket teams in the past 15 months -- ducking out of their game's biggest global tournament at the very first hurdle. However, with the fervour behind this home World Cup, the ramifications and backlash will be even more ferocious.

They have not risen to the criticism levelled at their scrum, despite Joe Marler offering Kaplan out for a coffee after the former South Africa referee questioned the loose-head's angle in the front-row. But when Graham Rowntree was asked whether he still had faith in his pack, the response was firm. "100%."

One of the various advertising and marketing campaigns in the lead up to the tournament focused around making England's players giants. The Twickenham crowd will be essential to reinforcing that on Saturday night. They need to rebuild the citadel after Wales gatecrashed it last week, and swell the chests of those on the playing field.

"I don't think that anyone in the squad has anything to say other than really positive things about this Twickenham crowd, they've been fantastic the last couple of years and have taken it to a new level," Launchbury said on Friday. "We'll definitely need that tomorrow and look forward to playing at home again."

The expectation and pressure has been ever-present this week and it will only grow in the hours before kick-off. Nerves will increase minute-on-minute.

Lancaster will wake with the dawn chorus on Saturday, go for a run followed by one of his solitary walks and then look for other distractions to stop his mind from playing over all the eventualities for the evening's match.

"I'll be up at six (in the morning). I'll work 95 times around the golf course," Lancaster said. "I won't go to the cinema again, that wasn't a very sensible choice last time [before the Fiji game], I picked the wrong film. Everest -- a story about a man going to the top of the mountain, a big storm comes and he dies ... "

England will arrive at Twickenham just under two hours before kick-off. They will do their usual walk through the crowd from the St George's cross-emblazoned coach into the depths of the stadium. Only at that point can they attempt to feed off the words of encouragement bellowed in their direction amid the beer vapours hovering in the early evening sky. It will be an experience like awakening from hibernation.

"We're in here [Pennyhill Park] and our only avenue to get any perspective, the only people you meet from outside the camp, is the media. You don't get out of that bubble," Lancaster said. "All you feel is the pressure and the comments made by people who are here or former players or coaches.

"You have got to get beyond that and try to get people to understand there is a whole country out there behind the team. That can be felt from the way the players are carried to the changing room by the crowd or the 80,000 people that are there or the sheer goodwill behind the team.

"I think there is a lot of goodwill behind the team. I think people have recognised how the team has developed in four years. It is a young team, I'm not making excuses for that -- it's my responsibility to pick the team.

"But it is a young team and I think people like the fact they play with pride and they have a crack and we don't always get the decision-making right but you can see they genuinely care about playing for England. The boys care massively about this result, I can assure you."

And then will come the warm-ups and the chance for Lancaster to say his final words to the team. Pre-match predictions, comments and words of wisdom will be consigned to housing fish and chips. Clutching his leather-bound diary, Lancaster will tell his players to win the match for the nation. A colossal amount rests on this.

"[I'll tell them] To do it for the rugby clubs and the mums and dads and the kids that play rugby, for their families, for the former players. But ultimately, for them to do it for themselves. They are the ones who have put the graft in; they are the ones who have to sit in the changing room before the game. I think there are some brilliant players in there, who are brilliant players now but just going to get better in the future. This is a big moment for them. For all of us."
