Steve Hansen has refused to outline defending champions New Zealand's biggest threats to making history by retaining their Rugby World Cup crown.
All Blacks boss Hansen's deadpan response to being asked for New Zealand's top challengers was to name Argentina - the 2011 World Cup winners' opening Pool C opponents.
"Argentina," replied a tongue-in-cheek Hansen when quizzed on the greatest threats to New Zealand's crown.
"They are the next game we play so they are our biggest threat. ... We haven't earned the right to sit here and say who's going to play in the semi-finals, quarter-finals or finals."
