Ryan Jones is confident Wales have it in them to leap over, skip round or power through any hurdle Ireland set in their path to nail a first Grand Slam since 1978.
There has not been a bigger day in Welsh rugby in Jones' lifetime. After victory over Scotland on Sunday, Wales are one step away from finally shedding the weight of glories now nearly 30 years in the past.
But there is not a hint of nerve or fear in the squad and Jones, who scored his debut Test try against Scotland to kick-start Sunday's onslaught, believes Wales can overcome whatever Ireland can throw at them.
''The performance at Murrayfield was another string to our bow. We knew we had it in us, we had to assert ourselves and we did that from the off,'' he said.
''We proved in France we have the fitness and physique to compete at the top level and we have shown against Scotland we have a good start in us.
''If we can pull both of those together then who knows what will happen next week? We know what our capabilities are.
''We haven't achieved anything yet and we are really aware of that. We so desperately want it (the Grand Slam) and the only way to get there is methodically.
"If we miss any stages we could be in for a big fall, which is going to be a nightmare for everyone involved.
''We are on the brink of something very special but it can all go up in a puff of smoke next weekend if we get stuffed by Ireland.
''We are not naive. It is the biggest game in Welsh rugby for years and years but we will approach it like any other game and play in the style we have adopted and made our own.
''With the boys in our backline we are going to score tries. We are not afraid to throw the ball around.
"It is high-risk rugby and we will make mistakes and concede tries, but we are not afraid to try things. Hopefully that will pay off.''
