Eight teams will fight it out for the 2012 4x4 world futvolei title, in a sport more often seen practiced by two teams of two. Anyone unfamiliar with the mixture of football and volleyball (you'd guessed already?) is likely to be knocked bandy by the skills on display, putting your average ball juggler to shame with athletic bicycle kicks and deft headers a part of every other point. Definitely worth a visit to see the best in the world battle it out at a sport that even your average carioca amateur looks depressingly adept at.
