Challenge Cup final: The numbers game as Rhinos face Robins

25: Leeds are appearing in their 25th Challenge Cup final seeking a 13th win - only Wigan, with 30, have more final appearances. A defeat for the Rhinos would set a new record of 13 Challenge Cup final reverses - they currently share the unwanted record of 12 with Hull FC

7: Hull KR are appearing in their seventh Challenge Cup final, having previously won just once at the showpiece event - by 10-5 against Hull FC in 1980. The Robins’ last Wembley appearance was in a 15-14 defeat by Castleford in 1986.

49: The Rhinos have the overwhelming advantage when it comes to Challenge Cup final experience - with a combined total of 49 appearances in the showpiece event in their squad compared to just five in the Hull KR ranks. The Hull KR players with previous Challenge Cup final experience are Graeme Horne, Tyrone McCarthy and Shaun Lunt, all for other clubs.

25: The Robins have 25 players yet to appear in a Challenge Cup final, compared to 10 Rhinos players awaiting their debut at the event.

4: Leeds coach Brian McDermott is taking charge of his fourth Challenge Cup final, having previously coached the Rhinos at Wembley in their 2014 victory against Castleford, which followed defeats in 2011 and 2012 to Wigan and Warrington.

1: Hull KR coach Chris Chester, in his first full season as a head coach, takes charge of his first Challenge Cup final although he did play as a substitute in Hull FC’s 25-24 victory over Leeds at the Millennium Stadium in 2005.
