"It's hugely exciting for her," Knight said. "We've gone for her because we think she's a real impact bowler. I guess she's a bit of an unknown but she bowls wicket-taking deliveries and for me she's, if not the quickest, one of the quickest in the country. She gets bounce, and she's got skills, moves the ball both ways, and ultimately we need a team that's going to take 20 wickets and we feel like she gives us that. She can bang the ball in as well, there's not too many people queueing up to face her in the nets. I'm really excited for her to see how she goes."

Filer has taken eight wickets for Western Storm from four matches in the Rachael Heyhoe Flint Trophy so far this year at an average of 28. 62 and she took five wickets from as many matches in the Charlotte Edwards Cup at 24.80. Last season she claimed 11 wickets at 22.63 in the RHFT and one wicket in two Charlotte Edwards Cup appearances.

"I think probably at one point Danni probably felt like she was never going to get a Test cap," Knight said. "We picked her because we want her to play exactly how she does in the middle order in ODI cricket. She's one of the best players, and the best attackers, of spin in the world game for me and she makes it very tricky to set fields, she scores in quite unusual areas. That's exactly how I want her to play, how she does in white-ball cricket, have a little bit of a counter-punch and use her experience there as well."

Knight hadn't spoken to men's counterpart Ben Stokes since his side lost their opening Ashes Test to Australia by two-wickets in a last-evening thriller at Edgbaston on Tuesday. But she has picked the brains of seam spearhead and Nottinghamshire native Stuart Broad in the build-up to this game.

"I've spoken to Stuart about the conditions, he's played a lot of cricket here and this is my first ever game at Trent Bridge," Knight said. "Lots of really useful stuff on how to bowl on this pitch, how the pitch changes over the course of the cricket that he's played here."

"It's probably a little bit patchier than I expected and probably the groundsman wanted it," she said. "Actually we asked for a pitch with just good carry. The Canberra wicket was awesome for women's Test-match cricket, a bit of pace, the bowlers could get a bit out of it but you could also score runs if the bowler missed. So we wanted a similar wicket to that, but generally it's a pretty good wicket to bat on and I look forward to getting out there.

"In terms of the pitch, you want a nick to carry because sometimes we've played on softer, duller pitches where actually it's really hard to score runs if you bowl straight but also really hard to take wickets and that's not really the pitches, we don't have as much pace in the women's game that's conducive to get a result. The Dukes ball is a really great addition. The bowlers have certainly enjoyed bowling with it and you can get a little bit out of it for a lot longer. Probably the biggest challenge in Women's Tests has been taking 20 wickets and I think the Dukes will help that."

All of England Women's recognised batters have scored runs in the lead-up to this match, most notably opener Tammy Beaumont, who retired on 201 not out off 238 balls against Australia A in a three-day warm-up on a lifeless Derby pitch last week, where Knight, Nat Sciver-Brunt, Sophia Dunkley and Amy Jones all reached the 70s and 80s.

"The tempo that we went at and the pace we scored at was brilliant without being overly risky and aggressive, that was awesome," Knight said. "We want to go on and make real match-defining innings, not just get a hundred if you can get a real big one. That puts the team in a great position. I'm really happy with the group and hopefully we can go out and replicate some of that in the next five days."
