Those are the first points that St Helens have conceded in the competition so far this season as they have romped to the final.

Going behind adds a whole new dynamic to this contest.

It's we attack, you attack. It's like a basketball game.This time it's Saints' turn to threaten, only for that to be snuffed out by a good claim by Tasha Gaines.

Leeds are finding pockets of space behind the play-the-ball to roll down the field. Then when Saints full-back Rebecca Rotherham spills a high kick not far from her own line, she is bailed out by an offside call against the Rhinos.

Saints have strength all over and their power players are strong and they get success on the edges.

Leeds obviously want to combat that and close them down.

St Helens ran out 28-0 winners when these sides met in the Grand Final back in October.

They seem pretty well matched so far, with both sides putting everything into this.

That's twice down at the right end of the field for Saints but it's stopped due to the lack of execution.

What's worrying for the Rhinos is they need to recognise that's where the threat is and it was six on three there.

The end-to-end nature of this game continues as Saints power foward. Jodie Cunningham tries a pass to put in Leah Burke but the winger can't quite gather.

This is a breathtaking start! St Helens turn the ball over and Zoe Hornby breaks away to set up field position for Leeds. Pressure back on Saints.

Courtney Winfield-Hill kicks for the corner but the ball just bounces agonisingly out of play.

St Helens take play right down the other end and hoist a high kick into the Leeds 22. Fran Goldthorp can't gather, handing Saints a scrum deep in Rhinos territoy. This is a chance.

Some good probing from Leeds in that opening set, with Courtney Winfield-Hill and Georgia Roche at the heart of it. They will be key for Leeds this afternoon.

On the last tackle the Rhinos try a grubber kick which goes dead.

Courtney Winfield-Hill goes for a short kick-off, a Saints hand puts it into touch after the holders are caught out.

Leeds will have the game's first set in Saints territory.

And we're off. This is the first time these side have met in a women's Challenge Cup final.

The showdown between rugby league's three Women of Steel could decide who wins the Challenge Cup when all-conquering St Helens face fellow giants Leeds in Saturday's final at Elland Road.

St Helens are hot favourites to lift the trophy after a clean sweep of all the major silverware in 2021 and having reached this year's knock-out finale without conceding a try.

But Saints' captain, and current Woman of Steel holder, Jodie Cunningham has warned her team-mates not to take Leeds lightly - especially as the Rhinos line-up will include the only other two women to win the game's most prestigious individual award.

"They have threats all over the park, but the one I'm excited, and a little nervous to see, is Georgia Roche," admitted Cunningham, in this week's 5 Live Rugby League podcast.

It is a tradition that 'Abide with Me' is sung before a Challenge Cup final and Lizzie Jones is again on hand to perform a beautiful rendition.

It tells you kick-off is not far away.

Reigning Challenge Cup holders St Helens have been in hugely impressive form on their way to the final.

They have not conceded a try in this year's competition and thrashed Featherstone 82-0 in their semi-final.

Leeds had a much more tricky tie in the last four, edging past last year's beaten finalists York City Knights 28-26.
