England manager Martin Johnson insists he has no plans to overhaul his coaching staff after receiving the backing of the Rugby Football Union.
England won only two of five games in the Six Nations and were criticised for a perceived lack of attacking flair.
"I don't anticipate making any changes," said Johnson. "I thought the coaches did an outstanding job this season, particularly in the autumn.
"In my opinion the criticism is ill-informed a lot of the time."
Ex-England prop Jeff Probyn has called for an overhaul of Johnson's coaching team and for Steve Borthwick to be stripped of the captaincy.
Criticising has become the thing to do in English rugby

"I don't think it's time for Johnson to go - I think it's time for his coaches to go," Probyn told BBC Sport on Monday.
Probyn lays the blame for England's lacklustre displays firmly at the door of back-up coaches John Wells (forwards), Brian Smith (attack), Mike Ford (defence) and Graham Rowntree (scrum).
"Johnson has got to start making the decisions a manager has to make and if that means some of your friends have got to go, they've got to go," he added.
But Johnson, who takes his team to Australia in June, mounted a robust defence of his coaching team, dismissing the criticism as unjustified.
"Criticising has become the thing to do in English rugby," said Johnson, who was appointed in 2008 with no coaching experience. "Mistakes happen on the field - perhaps coaches get some things wrong. But a lot of the time it's a player's error which is also a factor.
"People ask 'what are John Wells' credentials?' The guy has coached the most successful domestic team in English club history (Leicester), winning four championships on the trot and two Heineken Cups. Then he coached England to a World Cup final.
"Who's got better credentials than that? That's my mindset. Everyday he does a fantastic job. You see the criticism thrown in by people and you think, what the hell do you know about it?"
As Johnson hit back at his critics, RFU chairman Martyn Thomas insisted that the board's position had always been that the former England captain should stay as manager and lead the team in New Zealand for the World Cup in 2011.
"The RFU management board discussed the ongoing media speculation about the England team management and our elite rugby department and were unanimous in their view that it is unwarranted and unsubstantiated," said Thomas.
"The RFU has consistently said that Martin Johnson will be the England team manager through to the World Cup in 2011 and that remains our position.
"In that role he has to have the freedom to appoint the coaching team he thinks will best support him and equally that position has not changed.
"Over and above that, contrary to assertions in some media, there is no planned review of the elite department or the wider RFU in July following the summer tour."
Andrew admits Six Nations disappointment
Former England internationals Matt Dawson and Lawrence Dallaglio, have also demanded a change in personnel - including director of elite rugby Rob Andrew.
But Andrew rejected Dallaglio's comments, insisting he would still be in his role in 2011.
"No, I'm not going anywhere before the World Cup. I'm very comfortable in the role I'm playing and where the department is at," said Andrew.
"Lawrence is entitled to his views. We have to look at why that's happened and how we move forward."
England are due to play two Tests against the Wallabies and two midweek matches, before completing their five-match tour against the New Zealand Maori on 23 June in Napier.
