Maybe there's been a mix up and the Palace revenue numbers are actually for the Sainsbury's next door.When you look at both clubs, the state and capacity of the stadia, ticket prices, the outlets within the ground and what they generate etc etc 20% seems small to me. Palace beer/food generation must be tiny in comparison to Albion, corporate income too.
Who would want to use Selhurst for anything? Although maybe due to restrictions in what our stadium can be used for outside of football (lingering NIMBIES) we're not that different in that metric? Perhaps the true indication is against clubs like southampton, Leicester.
Just something that always surprised me, with the attendances and corporate beast we've become I'd expect greater difference but perhaps thats naieve expectations
