IF you are lucky enough to be in Cardiff today, and get a chance to speak to Dai, Dewi or Garreth, or indeed any Welshman; ask them about the relationship between Wales and England.

But what about the tries that bind ourselves and our Celtic cousins? From JPR Williams to the remarkable Leigh Halfpenny? Since 1882, we have met 120 times and, as things stand, Ireland have come second on 65 of them, been victorious 49 times, and finished on equal terms on six occasions. Today, with the prospect of a Grand Slam in reach for us and a Championship in play for them, one can expect the spring air to be thick with skin and hair flying.

And the Herculean Paul O'Connell marks his 100th cap.
The stage is set for a Homeric encounter, all we need now is to locate a Welsh Achilles heel.
