Full-back Leigh Halfpenny admits the pressure of being Wales' goal-kicker gives him a "horrible" feeling in his stomach but considers himself to be in a "privileged" position.
The 24-year-old continues to conquer his nerves, though, kicking six from seven attempts at goal as Wales won 26-9 over Italy in Rome in the third round. He missed just one from eight in the previous games against France and Ireland.
Meticulous preparation, he says, is the key to handling the "nerve-wracking" experience.
