Andy Robinson has dismissed suggestions he might have lost the dressing room following England's RBS 6 Nations Championship display against France in Paris.
The England coach hit back at suggestions the link between his players and the coaching staff had been broken.
"As regards such comments, the dressing room is actually a very positive area," he said.
"I am very happy with what is happening there. There is a real spark among the players and a desire to get things right against the Irish.
"I have no doubt about what we are trying to achieve, or the potential of the squad.
"We had a game plan for Paris. I used the expression we wanted to strangle the French game plan, but the truth is we failed to achieve it.
"We have worked hard this week, and we need to get the execution of our plans exactly right.
"You get judged on every single Test match you play, that is why it is such a great environment to be in. I've picked the team, and I am very confident with the team."
Robinson has rung the changes for the visit of Ireland, who are chasing a second Triple Crown in three seasons, and they have not lost to England since March, 2003.
"We changed things because of last Sunday's performance," said Robinson, reflecting on the major surgery he carried out in selection.
"But we are developing a squad, and the guys coming in are getting a deserved starting chance. We are concentrating on ourselves, and there could be a backlash against Ireland.
"You have to look at situations with total honesty in terms of selection, and I believe we have.
''The next game is always the hardest and the biggest,'' he added.
''Ireland have some very dangerous runners. We saw what Shane Horgan has to offer on the Lions tour last summer, then there is the Brian O'Driscoll/Gordon D'Arcy centre partnership as a proven pairing.
''Peter Stringer has had his best tournament, Ronan O'Gara is operating very well, and then there is the running of Geordan Murphy.
''Their pack is very streetwise and experienced, so it is going to be about who takes control out there.''
The RBS 6 Nations Championship 2015 was not poised to go down as one of the more "vintage" Championships, though there was great anticipation as the action headed into its final day. What transpired was something that nobody could foresee: "The Greatest Day in Rugby's Greatest Championship."
