Ireland hooker Rory Best believes head coach Declan Kidney has transformed the nation's fortunes since taking charge of the side.
A victory for the Emerald Isle over Scotland at Murrayfield on Saturday would leave Kidney's charges just one victory away from a first Grand Slam since 1948, the only other time they have managed it.
For former Munster boss Kidney to surpass predecessor Eddie O'Sullivan's three Triple Crowns in four years during his first season in charge would represent a remarkable achievement.
Since taking over last summer, Kidney has banished the memories of a woeful 2007 World Cup campaign and reversed the nation's RBS Six Nations fortunes after finishing fourth last time out.
And Best believes Kidney has installed some new found belief into the side, evidenced by the fact the players are performing so well on the pitch.
"Declan has re-instilled the confidence that we had two years ago back into us," said the Ulster hooker, who has been recalled to face Scotland at the expense of Jerry Flannery.
"The boys are a lot more buoyant and he's made us believe in ourselves again. For the past year and a half that wasn't really there.
"When results and performances don't go your way it's hard to be happy. But Declan has kept telling us that we are a good team and a good bunch of players.
"Now that we have a couple of results under our belt the Ireland camp is a good place to be.
"You only need to look at Declan's track record to know his way works.
"He's won two European Cups with Munster which many people thought couldn't be done. You have to appreciate what he's achieved."
