It was Wales' first-ever Grand Slam at under-20s level and included a particularly sweet 42-16 win away against England in round four.

"In today's Wales v Italy match programme, prop Samson Lee gives an insight into his feelings as an international rugby player from a Travellers' background.

"The interview for the Welsh language article by BBC Wales' Rugby Correspondent Gareth Charles was done before the match against England and the subsequent row over Joe Marler's "Gypsy boy" comment.

"I believe I am the first international rugby player with a Traveller background and I'm very proud of who I am and what I have managed to achieve on behalf of Travellers," he says.

"Well, that depends on your viewpoint. Wales coach Warren Gatland believes places for summer tours are on the line, saying the game is a "stepping stone" to New Zealand.

"And neither has the fact that the only prize up for grabs is second place deterred the fans.

"Cardiff is it's usual match day mix of red shirts, daffodils and sparkly cowboy hats. It's not haute couture, but then Cardiff is not Milan."

And then, as darkness falls, the real buttock-clenching, toe-curling, behind-the-sofa part of this three-act drama.

England came a cropper in Dublin in 2011.

The wheels fell off the chariot in spectacular fashion in Cardiff in 2013.

This time - in Paris - can they finally make a Grand Slam bid stick for the first time since 2003?

Scotland stand on the brink of history.

Relatively minor history, but history nonetheless.

Before last weekend, their last back to back wins in the Six Nations were in 2013.

You have to go way back to 1996 when Italy were still to join the party to find the last time they won three successive matches in the tournament.

Ireland came into this tournament as defending champions and could leave it with a miserly fifth-place finish. They are badly in need of a pick-me-up win.

England have scooped the silverware. That mystery is solved. But this year's climax is still more densely-plotted than a Dickensian doorstopper.

First up Wales coach Warren Gatland has told his players to "redeem themselves" after last weekend's defeat by England by walloping Italy.

Being on Warren Gatland's naughty step is not a place you want to be. But then neither is the receiving end of a dressed-down psyched-up Wales team.

Kick-off in Cardiff is 14:30 GMT.

This year there are more subtle subplots and storylines to get your teeth into.
