http://http://www.bbc.co.uk/sport/0/football/20456791 Surely if a game is ticket only, it's a bit daft to print too many tickets!
Daft indeed. I think the problem is in the unseated areas, you just get a ticket. And someone forgot to keep count of how many they had sold. The game was live on TV as well and they will have to refund all the tickets and then resell for the rearranged game. Someone will be feeling very sheepish...
