Only two points separate three teams at the top of the Guinness Six Nations table going into the final round of fixtures this weekend, with Wales leading the way after claiming their fourth straight win on Saturday.
The Welsh, who edged out Scotland at Murrayfield, can complete a Grand Slam if they win at home to Ireland, but defeat would open the door to England who are expected to see off Scotland at Twickenham in their Calcutta Cup clash.
England remain strong contenders after picking up their third bonus point when they ran in eight tries in their thumping victory over Italy on Saturday evening.
Wales remain the favourites to take the title, but they are sure to face a determined challenge from Ireland, who began the championship as the market leaders.
