England manager Martin Johnson has insisted he won't respond to "hysterical" critics calling for his coaching staff to be sacked and would stand by his backroom team.
Either side of a deeply uninspiring win over Argentina, England were well beaten this month by both Australia and New Zealand.
Ex-England internationals Josh Lewsey and Will Greenwood, who both played in the 2003 World Cup-winning team that Johnson captained, said their former skipper had to make changes.
Johnson, who in just over a year in charge has overseen six wins from 14 Tests with eight defeats, was urged by a number of critics to dispense with the services of forwards coach John Wells and defence coach Mike Ford, both of whom have been members of the England set-up since 2006.
Attack coach Brian Smith, the former Australia and Ireland international, was also in the firing line after England managed only one try in their three November games, against the Pumas, and looked desperately short of ideas when in possession.
No changes
Johnson insisted he was ready to make changes if it would increase England's chances of winning the 2011 World Cup but that now was not the time.
"The easy thing for me to do would be to go, 'Yes, you are right', sack x, y and z and buy yourself some time and blame someone else," he told reporters.
"That would be easy to do but it wouldn't be right. Surely not. It is not nice to sack people but if I thought the decision was in the best interests of the team, I would make it.
"If we have not been playing well, which we haven't, we will stand there and take criticism. But some of the criticism has been so wide of the mark and almost hysterical."
England elite rugby director Rob Andrew, having been involved in the decision to appoint Johnson despite the latter's lack of coaching or management experience, made it clear the former lock was not going anywhere before the 2011 World Cup.
"We appointed Martin 18 months ago to take the team to the World Cup in 2011. There will be some bumps in the road and we will learn from those and move forward into the Six Nations and beyond.
"Martin has never used injuries as an excuse but he has had to build a new team," he added.
