After a memorable 2022 that included a Test series triumph over the All Blacks in New Zealand, a Six Nations clean sweep would be the ultimate statement six months out from the World Cup in France.
England are in a different boat. With their title hopes mercilessly crushed by a rampant France at Twickenham last week, Steve Borthwick's team arrive in Dublin with two main aims: restoring pride and spoiling the Irish party.
England are not the only side with designs on raining on Ireland's parade, of course, as France can still retain their title. To have any chance, however, Les Bleus must beat Wales in Paris (14:45 GMT) before Ireland and England take to the pitch on Lansdowne Road.
'Super Saturday' opens with Scotland hosting Italy at Murrayfield (12:30 GMT), which is live on BBC One.
