It's two from two so far, but now comes the acid test for Adam Griggs' Ireland when they take on the defending Women's Six Nations champions England on Sunday.

The game at Castle Park in Doncaster, kick-off 12.45pm, will see the two remaining unbeaten teams in the competition go head to head. And Griggs has declared: "We are challenging ourselves against a world class opposition."

That said, after wins over Scotland and Wales, it's very much a case of building on the solid foundations laid down in those victories.

The Irish coach expanded on this when he spoke to RTÉ Sport's Damien O'Meara.

"We need to merge a couple of things we did well in those two games this Sunday to make sure we put them together for a performance," he said.

"You have got to respect what England have done and how they go about their business because they are very good. We made a point of getting our previews on England done early so as to focus on ourselves.

"If we can get some of our own systems and processes right, we believe we can put England under pressure that they haven't had before. Ultimately you want to make them come up with some answers and scramble a little bit more than they've had to around the set-piece and around the breakdown. When they get front football they are very good.

"We've got nothing to lose. We are challenging ourselves against a world-class opposition. Not every team gets to go up against such opposition but we now have that opportunity and we've got to make sure we're excited.

"We are looking for the performance. We have to judge ourselves off what we know we are doing and what we are trying to do. If we come back in a week later and throw the book out the window, we won't make any improvement."

Griggs also spoke about the time spent in the IRFU's High Performance Unit alongside the men's and U20 squads.

"There's a good buzz around at the moment," he added.

"Everybody is rubbing shoulders and there is a good vibe about the place. 

"That is important to us. We haven't been in this situation for a couple of years, with back-to-back wins.

"We probably underestimated how big being part of the Unit was going to be - the effect of rubbing shoulders with those other players. They are human, as well as us."    

Ireland have made two changes to their team from the win over Wales.

Aoife Doyle starts on the wing, replacing Beibhinn Parsons, who is taking time away from rugby to concentrate on her Leaving Cert preparation, while Katie Fitzhenry makes her first appearance of the tournament at centre. Michelle Claffey drops out of the squad.
