In a career that has featured almost as many problems as successes, the Hong Kong sprinter Lucky Nine is now enjoying one of the few trouble-free periods of his life.

And to his trainer Caspar Fownes, that is an ominous sign.

Lucky Nine has had to deal with some of the world's best in a career that has taken him from Ireland to Hong Kong, to Japan three times, to Dubai, Singapore and now Australia.

He's also had several issues to deal with and Fownes is conscious at least one of those could reappear at any moment.

But after a week in Melbourne, horse and trainer are making the most of the good times.

"He's rising seven-years-old, but he's remarkable," Fownes said after watching Lucky Nine gallop at Werribee on Monday.

"The most important thing with this horse is the internal issues he's had.

"He's a pretty bad bleeder but we've still managed to get some good results out of him.

"After his last five gallops he's been scoped and he's been completely clean."

Fownes said Lucky Nine has never had a verified bleeding attack, but internal examinations invariably show substantial blood in his trachea.

As in Australia, Hong Kong rules call for a horse to be banned for three months after a bleed and barred from racing if they suffer a subsequent attack.

Lucky Nine is being prepared for the Manikato Stakes at Moonee Valley on Cox Plate eve, October 25, and the Patinack Farm Classic on the final day of the Melbourne Cup carnival at Flemington.

Fownes has no doubt he is up to the task.

"He's going really well, he's settled in beautifully, eating well, everything," he said.

"He did a nice bit of work this morning and he's got a lot more to give."

The trainer also welcomed the slashing performance of Samaready in Friday night's Group One Moir Stakes at the Valley, an effort that stamped her as Melbourne's leading sprinter.

"She'll take the heat off us, she'll be favourite, I like that," he said.

Lucky Nine hasn't raced since winning the Singapore International Sprint in May in which he beat Australian contender Bel Sprinter.

Fownes said the horse had improved since that run.

"He went home and had a bit of a break and let down nicely and got his body weight back up," he said.

"I think he's actually improved again, he's pleased me."

Fownes, a two-time champion trainer in Hong Kong, has left jockey Brett Prebble to handle Lucky Nine's preparation at the Werribee quarantine centre.
