Mark Chapman introduces live coverage of the Challenge Cup final. Castleford visit Wembley Stadium for the first time in 28 years, where they face 11-time winners Leeds.
In the quarter-finals, Castleford Tigers knocked out Wigan, who have won the cup more times than any other side, including a 16-0 win against Hull FC in the 2013 final. They will hope to win the Challenge Cup for the fifth time in their history, the last time being in 1986.
Leeds Rhinos beat Warrington Wolves 24-16 in their semi-final. Despite winning six league titles over the past decade, they have been serial runners-up in the cup competition in recent years, losing six finals since they last lifted the Challenge Cup in 1999.
