Jamie Heaslip has warned Wales that Ireland will take a team of winners to Cardiff as they attempt to wrest the Grand Slam from their RBS 6 Nations rivals.
Victory at the Millennium Stadium would secure Ireland's first championship honours since 1985 and complete their first clean sweep for 61 years.
Wales start the match as favourites but their target of needing to win by at least 13 points to successfully defend their crown puts the Irish in pole position for the title.
Heaslip is confident he will be celebrating the Grand Slam on Saturday night thanks to a talent-packed line-up led by skipper Brian O'Driscoll.
"We've got a great coaching staff but we also we've got Heineken Cup winners and Magners League winners in the squad," he said.
"These are guys who have won different things throughout their careers. We've got Lions players and the captain of the Lions is our captain. We've got great quality both on and off the pitch.
"The staff are going to try and get us into the best shape and give us the best of everything right up to the game. But once that ball is kicked off, it really boils down to the 22 guys who are involved."
Heaslip may soon be a Lion himself come the summer tour to South Africa after emerging as one of the most exciting players of the RBS 6 Nations.
Two crucial tries against France and Scotland point to a big-game temperament while the Leinster number eight's athleticism and appetite for work have made him a central figure in the Irish team.
However, his form did not stop head coach Declan Kidney from dropping him for the 22-15 victory over Scotland.
"It's natural not to be happy when you're left out of the team, especially if you've been starting and things have been going well," said Heaslip.
"But once the coach makes a decision, you've got to go with it. You're not going to change his mind. Granted, I sat down and talked with Declan, but I knew talking with him wasn't going to change his mind."
Mako Vunipola, Courtney Lawes and Ben Youngs will all start for England in Rome, with Saracens' Maro Itoje finally set for his debut from the bench as Eddie Jones adjusts his line-up ahead of their trip to Italy.
