Clare Balding presents live coverage of the Challenge Cup fifth-round tie between West Yorkshire rivals Wakefield Trinity Wildcats and Castleford Tigers. Visitors Cas started the season in great form but have gone off the boil in recent weeks, while financial problems have contributed to Wakefield's current lowly league position.

One man who knows plenty about cup success is Wakefield head coach John Kear.
