2. What are you most nervous about with the All Blacks?
WG: Referee Jerome Garces taking a dislike to the All Blacks work, especially around the scrum and breakdown and offering Handre Pollard a stack of penalty attempts. That will have a knock-on effect on the All Blacks' confidence.
DC: All Blacks fans wouldn't want to see them get sucked into a set-piece battle. To my mind, the All Blacks should go out and play like they're trying to win by 30. If they come up 20 points short of that target, so be it. Sometimes when you tell yourself it's going to be a tight arm wrestle, that can almost work as a self-fulfilling prophecy.
3. Australia or Argentina?
WG: The Wallabies used all their luck last week. This week they'll bring their A-game, which will agitate the Pumas. They nailed two late tries against Ireland which inflated the winning margin in a game which was very tight until the last period.
DC: Australia quite comfortably. If it was an Argentina-South Africa semi I'd back Los Pumas, but Australia have had their number in this World Cup cycle, winning six of seven meetings. If Argentina play the ball-in-hand, phase-to-phase style they successfully employed against Ireland, then Michael Hooper and David Pocock (if fit) could have a field day.
