Trailfinders' England captain Meg Jones says they are targeting an "underdog victory" in their first Premiership Women's Rugby (PWR) final.

"I honestly didn't think I'd be here," Jones told BBC Sport. "It would be an underdog story and mean a huge amount to the club. And on the back of the season we've had, it would mean a great deal to me as well."

Jones, 29, only joined Trailfinders from Leicester ahead of this season, alongside the likes of Scotland captain Rachel Malcolm and Canadian international Clare Gallagher.

Jones admits she didn't expect them to be challenging the PWR final.

"Probably not at the start of the season, but I don't actually think that far ahead. There are so many variables.

"We always set for the top four, and when we'd beaten Gloucester [in the regular season] a couple of weeks before the play-offs, we thought 'Wow, we're really clicking here. We know the plan'".
