John Inverdale is joined by guests Keith Wood and Jonathan Davies at the Millennium Stadium as Wales seek their first home win in this fixture since 2005.
Both nations have won the Grand Slam in recent years but they have made a faltering start to the 2011 tournament. Wales were beaten at home by England, while Ireland only narrowly overcame Italy before losing to France. Wales did at least end an 11-month winless streak by defeating Scotland in February, thanks in no small part to all-time leading try scorer Shane Williams. Ireland have stagnated since winning the Grand Slam in 2009, and the last time they put in a performance to get the pulses racing was against Wales in the 2010 Six Nations. Can Declan Kidney's side rediscover their verve in Cardiff?
