Cheika accidentally reveals Wallabies' game-plan for Rugby World Cup final

Australia have blundered on the eve of the World Cup final by accidentally revealing elements of their game-plan for dethroning New Zealand.

Wallabies head coach Michael Cheika and his assistant Mario Ledesma gave away the information at the captain’s run at Twickenham by conspicuously holding pieces of paper carrying details that were intended to remain secret.
