The Watersplash final. Martin Offiah’s long-range try against Leeds. Brett Kenny against Peter Sterling in 1985. Sheffield Eagles’ upset of 1998. Some of rugby league’s greatest-ever moments have been played out at Wembley Stadium.

The customary residence of the Challenge Cup final since 1946, barring the occasional move because of redevelopment, HA9 has been home to tradition, glory and sporting drama. And this Saturday, Wembley will again host the decider of rugby’s oldest cup competition when holders Hull KR defend their crown against Wigan Warriors.

But while history surrounds the hallowed London turf, the Challenge Cup hasn’t moved with the times. A crowd of only around 60,000 is expected at Wembley this weekend, which will leave it one-third empty. The Cup has an attendance problem and it is only getting worse.

The Challenge Cup final hasn’t cracked more than 80,000 fans since 2015, when Leeds thrashed Hull KR, and three years ago just 58,213 turned up to see Leigh defeat the Robins. Average crowds have gone from the mid-70,000s to the mid-60,000s since 2017, and now are declining further.
