Lomu played for New Zealand in two World Cups

Former All Black great Jonah Lomu says World Cup favourites New Zealand can still raise their game several levels before next year's tournament.

Speaking after seeing them crush England 41-20, Lomu told BBC Sport the All Blacks would only get better.

"It looks good but I'm pretty sure they won't be satisfied - they're still a work in progress," he said.

"The scary thing is that with a year to go, there's still some great players back home who could put their hand up."

Since winning the inaugural tournament in 1987, the best New Zealand have managed in the World Cup is finishing runners-up to South Africa in 1995, the year Lomu stormed onto the world stage.

But despite the great emphasis that is laid on maintaining the tradition of wearing the black shirt, Lomu said making amends for years of World Cup disappointment was unlikely to be on the minds of the current squad.

"You pay lip service to it, but it's not really much of a motivating factor," he said.

"They're all just focused on getting out there and winning it anyway."

Under former Lions coach Graham Henry, the All Blacks have racked up 29 wins in 33 games.

And with only one of the starting XV against England being aged over 30, there are signs he could be laying the foundations for a new dynasty of world domination.

"Graham has a great support staff with a fair bit of experience in terms of the UK and Europe," he said.

"He was up here coaching himself, and he's taken his experience from that as well as his Super 12 experience, and has Wayne Smith and Steve Hansen on board - that's a formidable coaching team.

"They've yet to finalise their 22 but it's exciting to see, particularly for New Zealand rugby."
