Lois Forsell's Rhinos have revenge on their mind after being beaten by the Saints in last season's final at Elland Road, and they also need a bounce-back performance after a shock loss to bottom-of-the-table Huddersfield Giants in Group 1 of the Women's Super League last week.
St Helens have fallen off the pace set by York Valkyrie in the league, but their most recently loss to Lindsay Anfield's side came in the immediate aftermath of the stunning Betfred Women's Challenge Cup semi-final at Warrington which saw Faye Gaskin's last-gasp drop-goal send Matty Smith's women to Wembley at York's expense.
Sportsman stat: Leeds Rhinos back-rower Amy Hardcastle was St Helens' top try scorer last season with 27 tries in 15 matches playing out of her previous position of centre.

Much has been said in the build-up to Wembley about Rovers' last visit to the national stadium, when their 50-0 loss to Leeds Rhinos broke all sorts of records. They seem like a better prepared outfit this time around, with Willie Peters being very quick to remind his side that the job was far from done after their epic 11-10 golden-point win over Wigan Warriors in the semi-final. Captain Shaun Kenny-Dowall would love to walk away with the Challenge Cup trophy in his final game in the competition before his retirement at the season's end.
Leigh have made a mockery of everybody's pre-season predictions by not just staying clear of the relegation battle but going on a storming run up the Betfred Super League table to third and reaching a first Challenge Cup final in 52 years. Adrian Lam will hope his side maintain all of the values which have brought them this far when they step out on the hallowed turf on Saturday afternoon.
Sportsman stat: This is the fifth Challenge Cup meeting between the two sides in the last seven seasons, with Rovers winning each of the previous four in that time span.
