William Buick can envisage Thought Worthy making the progress to become a Ladbrokes St Leger contender.
John Gosden's colt will have to make up more than 11 lengths on Camelot on form from last Saturday's Investec Derby, as the top three-year-old is expected to be in the Leger line-up as he chases the first Triple Crown since 1970.
Buick and Gosden have teamed up to take the final Classic of the season for the past two years with, Arctic Cosmos and Masked Marvel, and the jockey was pleased with his fourth-placed finish at Epsom.
Thought Worthy is a full-brother to Gosden's 2007 Leger winner, Lucarno, in the same ownership.
"I don't think he had any problems at all, he ran very well and I was very proud of him," Buick said.
"It was a straight-forward race and he ran as well as I could have hoped, to be honest.
"Obviously the winner, Camelot, is an exceptional horse and different class in his age group, certainly. Main Sequence and Astrology are solid horses too, and he'll improve. Come September, he might just be right for Doncaster."
There was better news for the jockey in France on Sunday when he helped Gosden's Aiken stretch his winning sequence to six in the Grand Prix de Chantilly while Mick Channon's Laugh Out Loud came nicely clear in the Prix de Sandringham.
"All in all, it was a good day," he said.
"She (Laugh Out Loud) is quite highly-strung and it wasn't the strongest-run race but it wasn't falsely-run. She won on merit and beat what was once a strong English Guineas fancy in Mashoora. She'll have to go to the Coronation with a strong chance.
"Aiken is a very nice progressive horse and I think he'll be an exciting horse through the season. He just doesn't want it to be too quick but when the ground is in his favour, he's very useful."
