Lloyd Williams' focus is on winning another Melbourne Cup and his best two contenders, Efficient and C'est Le Guerre, take their next steps in the Underwood Stakes at Caulfield.

Both stayers have already indicated they are on target with excellent first-up performances, Efficient running fifth to Mic Mac in the Memsie Stakes (1400m) at Caulfield and C'est La Guerre fourth behind Vigor in the Makybe Diva Stakes (1600m) at Flemington.

The pair are among 14 Group One winners engaged in Saturday's 1800m weight-for-age feature which has attracted a full field of 16 plus three emergencies.

"It's going to be hot race. It is an important stepping stone for these two horses towards the Melbourne Cup," said Williams' son Nick Williams who is the managing part-owner of last year's Cup third placegetter C'est La Guerre.

Lloyd Williams has been in the ownership of three Melbourne Cup winners, the Tommy Smith-trained Just A Dash (1981), the John Meagher-trained What A Nuisance (1985) and the Graeme Rogerson-trained Efficient (2007).

"Dad has spent a lifetime trying to win the Melbourne Cup and that's again our focus," Nick Williams said.

"He has said, and I'd like to frame a market on this, that if Efficient won the Melbourne Cup again this year he'd consider taking him to England for (the) Ascot (Gold Cup) next year.

"So we'll wait and see if that does happen. I've seen him make those plans before and he's come up with a reason why he can stay at home. But I'd love to see that happen.

"I think Efficient has that X-factor if he really does come back to his best."

Williams said the grey proved he was "a somewhat special horse" when he won the Victoria Derby and came back the following season to win the Melbourne Cup, a feat only achieved once since Phar Lap completed the same double when he won the Cup as a four-year-old in 1930.

"It would be terrific to see him have the opportunity to take on the world's best," he said.

Williams said Aidan O'Brien, whose prepared Melbourne Cup third placegetter Mahler in 2007, suggested Efficient would do well in England.

"He (O'Brien) was certainly impressed because the stayers over there don't seem to have that turn of foot (that he has)."

Williams said he felt C'est La Guerre was a little sharper than Efficient going into the Underwood, a race his father won with the Rogerson-trained Perlin in 2005.

Jockey Steven Arnold agreed and picked C'est La Guerre as his Underwood mount ahead of Efficient who will be ridden by Nick Hall.

"He (Efficient) is yet to win under a mile-and-a-half (2400m) in open company. I'd be looking for him to rattle home but he's probably not going to sharp enough to win this race," Williams said.

"He's certainly going as well as he could be though."

Efficient was scratched from last Saturday's Dato Tan Chin Nam Stakes (1600m) won impressively by Whobegotyou, due to the firm surface at Moonee Valley.

Williams said his father and their private trainer John Sadler believed C'est La Guerre had furnished into a better horse this year.

"We've only had the horse from June last year. He was a very immature horse, he obviously has plenty of ability," he said.

"He likes the sting out of the track and he has strengthened a lot. I'm very confident we'll see the best of him this preparation."
