Clare Balding presents live Challenge Cup final action from Wembley Stadium in an intriguing showdown between Leeds Rhinos and Warrington Wolves, two of the best cup sides in the country. Reigning Super League grand final champions Leeds are appearing in their third successive final but having lost the previous two, including once to Warrington in 2010, so they will be desperate to make it third time lucky. Warrington are also no strangers to Wembley - this will be their third final in four years. However, unlike their opponents, the Wolves have been able to get the job done at the national stadium and lifted the trophy on both previous visits. Brian Noble, Ian Millward and Jonathan Davies offer expert analysis of the action. Show less
