A flash of form from a horse who had previously shown little has encouraged premier trainer Peter Moody to expect a vast improvement from his French-bred stayer Kesampour.

One of four well-credentialled imports Moody will saddle up at Caulfield on Saturday, Kesampour had shown little in either his track gallops or his racing since joining Moody.

At his only Australian start Kesampour finished seventh behind stablemate Ibicenco over 1700m at Caulfield two weeks ago.

They meet again in Saturday's Group Three Naturalism Stakes (2000m) and their trainer is expecting there to be little between them.

"I saw the improvement in him in his work today that I've been hoping to see for a couple of months," Moody said on Tuesday.

"He's getting closer all the time."

While Kesampour hadn't shown a lot until his latest gallop, Moody wasn't too unhappy with his Australian debut.

"He loomed to win that run and he's taken good physical benefit from it," he said.

Moody is also heartened by the form Kesampour showed at his final run in France in the Prix de l'Arc de Triomphe and his opinion of the recently arrived English horse Sea Moon who finished midfield in Europe's most prestigious race.

"He finished close up behind Sea Moon in the Arc, so you'd think that form would give him a chance in a Group Three race," he said.

"And Sea Moon is the greatest horse ever to be imported to Australia, bar none."

Moody also runs his veteran Manighar in the Group One Underwood Stakes, along with My Quest For Peace who has his first run for the trainer beyond 1400m.

My Quest For Peace worked brilliantly at Caulfield on Tuesday, but faces a stiff task against the likes of Atlantic Jewel and Puissance De Lune.
