Natasha Hunt
England World Cup winning scrum-half on Radio 5 live sports extra

It was interesting watching the anthems because the England girls were rocking around with massive smiles on their faces but Ireland were really focused, so it'll be interesting to see how both sides start.

England scored 12 tries in their last outing and Ireland's pack has been strong throughout this tournament.

So will these conditions favour the home side?

First scrum of the game and a huge push from Ireland. A good start.

A fantastic crowd at Donnybrook for this Grand Slam decider - only the second in Women's Six Nations history.

We're playing in atrocious conditions as the rain lashes down and the posts sway in the wind.

Ireland's Nora Stapleton gets us underway.

So a quick turnaround at Donnybrook, England U20s are cleared off the pitch and out come Ireland and England women to begin their battle.

Anthems to come...

If my words aren't enough, and you fancy using your ears as well as your eyes - we've got you covered.

With the U20s having delivered the goods, England's women now have the opportunity to add the second Grand Slam of the day.

They managed 12 tries against Scotland last time out, with winger Kay Wilson clocking a record seven scores on the way to a 64-0 win.

But standing in their way tonight are an Ireland side who are also unbeaten in this year's tournament.

And what could be better than beating the English on St Patrick's Day on home turf?

In the first game of the 'Donnybrook double' England U20s beat Ireland U20s 14-10, securing the first of three Grand Slams on offer for England rugby this weekend.

Tries from Jack Nay and Henry Walker gave England a 14-3 half-time lead but Ireland's Gavin Coombes scored with 15 minutes to play and set up a tense finale.

Ireland nearly spoiled the party, but were held up over the line with the clock on red after a fantastic defensive display from the men in white.

England had already secured the Six Nations title but claimed their first Grand Slam since 2011.
