Forsell was the first player to sign for the new women’s side when she moved from Bradford Bulls last winter on the back of her 2017 World Cup commitments.
She had already won the treble with the Bulls – traditionally fierce rivals of the Rhinos – but her allegiance was always at Headingley.
The Rhinos fan, who works for the club’s Community Foundation, fulfilled a childhood dream when she joined and will add to a whirlwind debut campaign with a trophy if Leeds can beat Castleford at Warrington’s Halliwell Jones Stadium.
“It’s a massive game,” the England international told BBC Sport.
“I’ve been involved in finals before but it’s a bit different this time, playing for my hometown club and captaining the side, creating history.”
Players have come from near and far to play for the Rhinos, some have also swapped the terraces for the paddock or even changed sports.
“The WSL brought a girl like Shannon Lacey to a taster,” Forsell continued.
“She played football before but was a life-long Rhinos season-ticket holder who got involved and ended up playing in a Challenge Cup final. It’s the power of the sport.
“Then there are people like Courtney Hill. She’s a professional cricketer from Australia and has come over to play a bit of rugby.
“She said she thought she’d come and have a shot. She too is about to play in a cup final.”
