Rugby World Cup final: Hooper & Pocock key to outcome - Lomu

Australia have won all six World Cup matches that they have played at Twickenham

New Zealand legend Jonah Lomu fears back-rowers David Pocock and Michael Hooper will give Australia the edge in the breakdown in the World Cup final.

Lomu believes the All Blacks' ability to nullify Australia's two breakdown specialists will determine the outcome.

"If there's any team who can give New Zealand a run for their money it's Australia because they're the only team to beat them this year," said Lomu.

"Australia's speed into the breakdown will give the All Blacks a headache."

Pocock and Hooper, both primarily open-sides, have formed an effective partnership and dominated teams at the breakdown.

Australia number eight Pocock has been instrumental in his team's progress to the final, securing 14 turnovers in the competition - five more than his closest rival, Fiji's Leone Nakarawa - despite missing the victories over Wales and Scotland.

Number eight Kieran Read has been New Zealand's most successful player at the breakdown, winning eight turnovers, with captain Richie McCaw securing six.

The Wallabies have only won one of their last 12 Tests against the All Blacks but that victory came six weeks before this World Cup, a 27-19 win in Sydney which secured Australia the Rugby Championship. New Zealand promptly won the return fixture in Auckland 41-13 the following week - against a much-changed Wallabies side.

Lomu, the joint-leading try scorer in World Cup history, added: "The difference at the moment is that New Zealand only have Richie McCaw in their back row, while Australia have Hooper and Pocock working together. That gives them a different dimension at the breakdown.

"The backs will get praise for scoring tries, but matches are won up front and the breakdown will be what makes the difference."
