A psychic sausage dog named R2D2 will predict the top match every day at the 2018 World Cup. The concept is simple - each day he is presented with a classic dish of the nation playing, and whatever he eats determines the winner. He has two attempts - if he chooses one type of food twice it's a win, and one each a draw. R2D2 has a 100% record so far, after correctly predicting Russia's Group A victory over Saudi Arabia.
