There is a 'sponsored' article on it published on Aug 23rd in The Telegraph - basically an advert - for people to join Club Wembley.
The Challenge Cup Final is not listed as one of the key selling points, and as has been pointed out, very few Club Wembley patrons take up their seats for the Challenge Cup Final.
There are also quite a few events at Wembley which are not covered by the Club Wembley deal, such as the upcoming RU matches.
When this is next negotiated, perhaps the RFL should exclude themselves from the Club Wembley deal, so that they can sell the seats direct, just like the other sporting events do.
Individual memberships continue until 2017. Is it fair to assume that from this date onwards the RFL could negotiate themselves out of future Club Wembley deals?
