Just 80 minutes separate Leeds, St Helens, Warrington and Hull KR from Wembley this weekend as the Challenge Cup semi-finals decide who will contest the final for the grand old trophy in its 120th year.

Friday's game between old foes Leeds and St Helens pits last season's Challenge Cup winners against the Super League champions, with plenty of last-four history between the pair.

Saturday sees Hull KR take on Warrington, with Rovers commemorating 35 years since their last Challenge Cup success when they beat city rivals Hull FC in 1980 - while their last visit to Wembley was in 1986.

For Warrington, the national stadium has far more recent memories, with three Cup victories in the past six seasons and a string of semi-final appearances, including defeats in the last two campaigns.

BBC Super League Show presenter Tanya Arnold, ex-Great Britain coach Brian Noble - who coached Bradford's 2003 winning team - plus 1998 and 2005 Cup-winning coach John Kear share their thoughts on the two fixtures.
