The highlight of weekend four of the RBS Six Nations looks set to be Wales' attempt to land the Triple Crown with victory over Ireland on their visit to Croke Park.

This match has a couple of fascinating sub-plots with Warren Gatland taking his unbeaten Welsh side to play against an Ireland side coached by Eddie O'Sullivan, his former assistant, who replaced the Kiwi as the Irish coach back in 2001 amid accusations of disloyalty and plotting.

The canny Gatland has played down any revenge motive in the media this week, but you can bet he will be using it as a motivational tool for his men before they enter the unique amosphere created at the new Irish rugby home.
