All Blacks coach Steve Hansen praises Argentina

All Blacks coach Steve Hansen has heaped praise upon Argentina following Saturday's 21-5 victory.

The Pumas trailed by one point at half time, only for the All Blacks to pull away in the final quarter.

"They're probably one of the best defensive teams in the world," said Hansen.

"And their one-on-one tackling is good. They're a very passionate team and have a lot of desire to play for their nation."

Argentina's introduction has seen the former Tri-Nations become the newly-named Rugby Championship.
