Former All Blacks coach Sir Graham Henry believes Steve Hansen's team just need more of the ball to "kill" the Wallabies but he said Kiwi rugby fans "should be worried" after last Saturday's Bledisloe Cup defeat in Perth.
The Wallabies thumped the All Blacks 47‑26 in the first of two Bledisloe tests ahead of the Rugby World Cup kicking off in Japan on September 20.
Australia last lifted the Bledisloe Cup in 2002 but they can break that drought with a win against the All Blacks on Saturday at Eden Park, a venue where the All Blacks have not lost a test since 1994.
Henry, admitted there was cause for concern after the All Blacks finished third in the Rugby Championship won by South Africa.
But he said simply improving their possession stats would lead to victory in Auckland this weekend.
The All Blacks and the Wallabies face off in the Bledisloe Cup decider at 7.35pm this Saturday at Eden Park in Auckland.
