MICHAEL McNAMARA: Offaly hurling manager and former Clare trainer and selector in the All-Ireland wins of 1995 and 1997, he has also played and coached rugby.
"I'm hoping the English come here a bit nervous, because otherwise there's a danger of an explosive start and then we're in serious trouble. When this English team get moving they're something special and they would appear to have too much firepower.
"Ireland need to be still there after 15 minutes, growing in confidence and you'd never know - England's back division has been found wanting in the past. Lansdowne Road hasn't been a happy hunting ground for teams chasing the championship.
"This management team seem to have brought something extra to the job and the win in Wales would never have happened in the past.
"Man for man, England are better but it's not played man for man. Still there's a public-perception doubt out there and it's impossible to protect players from it completely. Some of the players have been on the end of terrible hammerings against England and even the win two years ago was very unexpected at the time. My gut instinct is that we're in trouble."
CAITRIONA O'KELLY: Won her second Irish Senior Cup hockey medal with Loreto last week and has played for Ireland 47 times. Interest in rugby is high given her brother Malcolm will be playing in the second row tomorrow.
"Yeah, definitely Ireland can win this match. I think they'll do it for a few reasons. They have an ability now to stop teams playing the way they want to. They were able to do that against France and if they do it again England will get ratty, irritated and frustrated.
"I don't know if it's going to be a real fancy game and a lot will also rest with David Humphreys' kicking. But he's been playing brilliantly and I think he will rise to the occasion especially in Lansdowne Road."
JOHN TREACY:Former two-time World Cross Country champion, Olympic marathon silver medallist and now chief executive of the Irish Sports Council.
"I think we all realise that it's going to be a very tough game for Ireland. But I'm really glad that the game is being played at Lansdowne Road and not the other side of the water, and I think the home advantage will be a big factor. And from that point of view I would be optimistic that we can sneak it, and I'm certainly hoping to see a bit of history at Lansdowne Road
"The Irish defence has been our main strength all year and that will need to be at its best again tomorrow. I'm also glad to see Victor Costello back, and of course we have a truly world-class player in Brian O'Driscoll.
Having said that I think England are the best team in the world right now, with some incredible talents like Jonny Wilkinson. But we definitely have a great chance, and I'm really looking forward to being there tomorrow."
JOHN O'MAHONY:All-Ireland winning football manager with Galway in 1998 and 2001, and under-21 All-Ireland winning manager in 2002.
"I actually said at the start of the year that I fancied Ireland to win the Grand Slam and I see no reason to change that now.
"It is a huge game for Ireland, a one-off, and with the home venue and passion I think they will have enough to get them over the line and win it. And it would be a fantastic result.
"If you think about it logically, then England do have the greater firepower, and probably should win. But sport doesn't always work that way.
"And what has impressed me most of all about this Irish side is their team ethic, and how they've overcome various injuries along the way, and have been without Keith Wood for any game, and still played very well.
"It is a huge task but I very much think Ireland can pull it off. I'd love to be there as well, but it's really an occasion for true rugby supporters."
