Shane Williams, like Wales, is down and out at Croke Park.
Ireland coach Declan Kidney has set his sights on winning the Triple Crown against Scotland next weekend.
Keith Earls bagged a brace of tries to sink Wales, either side of a Tomas O'Leary strike in a comprehensive victory at Croke Park.
And Kidney reckons his side can clinch their fifth crown in seven years against the Scots in Dublin. Kidney said: "For many years we were not winning anything. But now we have the chance to win the Triple Crown.
"That game against Scotland next week will be like a cup final. We know what we have to do and it sets the game up nicely. It will also be a send off for Croke Park. It's been a great place for us to play while Lansdowne Road is being built."
Wales boss Gatland said: "I'm disappointed with the result but take nothing away from Ireland. They were very good and clinical. They took their chances very well. We had more territory and possession but turnovers have been costly. They kept the ball well and took the chances.
"The yellow card was very costly in the game. The most disappointing aspect is we haven't learnt our lesson from the England game and from a coaching point of view it's extremely frustrating."
The WRU has launched a campaign to create a long term legacy for Welsh club rugby by highlighting the advantages of volunteering. Rhian Edwards, a volunteer at Seven Sisters, has enjoyed many benefits of her volunteering at a grassroots rugby club including being part of the Rugby World Cup volunteer workforce after being nominated by the WRU - and the WRU is asking for more people to develop their 'Welsh rugby roots'.
Wales head coach Warren Gatland and captain Sam Warburton say their first prioirty on Sunday in the opening game of the World Cup is to win against Uruguay and not get overly concerned with points difference.
With only days to go until the biggest rugby competition in the world begins, rugby fans visiting Cardiff this autumn will be able to enjoy a special display at National Museum Cardiff as part of the celebrations surrounding the Rugby World Cup.
