The All Blacks, on the other hand, have been flying high since their win over the Springboks, but will be coming into the matchup cold after the cancellation of their final pool game against Italy.
While the All Blacks will be favourites going into the match, there is a very real possibility that the two-time reigning world champs will be knocked out at the quarter-final stage.
