Just found this on the BBC site:
The Football Association has explained its allocation of FA Cup final tickets.
Finalists Chelsea and Manchester United have each been given 25,000 tickets, with a further 17,000 seats taken by Club Wembley members on 10-year leases.
The remaining 23,000 tickets will go to other clubs alongside grass roots and other football organisations.

That's 17,000 prawn sandwiches.
