Brutal.

All Blacks captain Sam Cane has had a pop at New Zealand fans following his team’s shock loss to Argentina in the Rugby Championship last Saturday, saying some supporters have very little idea of what they’re talking about.

The 25-15 defeat was Argentina’s first-ever win over the three-time world champions and has gone down as one of the biggest shock defeats in recent memory.

But Cane, who replaced Kieran Read as All Blacks captain following his retirement after the Rugby World Cup in Japan, is doing his best to block out fan comments in the meantime, particularly those he says that lack validity.

Cane said the All Blacks have some “amazing fans” – but some “pretty brutal” ones too.

“I think we’ve got amazing fans but we’ve also got some pretty brutal ones,” Cane told Sky Sport’s The Breakdown.

“With that, you’ve just got to remind yourself that, hey, they may like to think they know a lot about the game of rugby, but in reality, they don’t really.

“And they may know the game from what they see in the 80 minutes but they don’t see a lot of stuff that goes behind the scenes.

“And to me, if I’m having my leadership questioned in the public, the people’s opinions who really matter to me are my teammates and the coaches who I work with every single day. And I’ve got a lot of confidence from them that we’re on the right track.”
