I generally support Australia and England in the group stage.
One day I hope to be able to support one of them in the final, but I am not holding my breath.
Australia are drawn with Spain, Netherlands and Chile; we might, perhaps, be able to beat Chile, but I can't see us getting one of the two spots in the round of 16 - Spain will likely win group B, and Netherlands I reckon will be second.
England are a better prospect to get past the group stage, drawn with Italy, Uruguay and Costa Rica; I would expect Italy to win the group, with England second; if so, England will play the winner of the relatively weak Group C (Colombia, Greece, Ivory Coast and Japan) in the round of 16, but then face the likelihood of meeting Brazil in the quarter final.
The survivors of the group G 'group of death' - probably Germany and Portugal - should brush past the top two from group H (Belgium, Russia, South Korea and Algeria), so my pick for the Quarter finalists are:
Brazil v England
France v Germany
Spain v Italy
Portugal v Argentina
Semi finals:
Brazil v Germany
Spain v Portugal
Final:
Brazil v Spain
Brazil must be favourites to win the title on home soil.
Of course, with my record for picking matches, this probably means Bosnia-Herzegovina will beat Algeria in the final
