Frankie Dettori does not see Aidan O'Brien's feat of training the first three home in the Prix de l'Arc de Triomphe being matched.
Dettori played his own part as he rode Ascot Gold Cup winner Order Of St George into third place at Chantilly behind stablemates Found and Highland Reel.
O'Brien had already enjoyed a stellar season, including saddling the first three home in the 1000 Guineas at Newmarket, but what he achieved at the weekend will surely top a list of his greatest achievements.
"I'm definitely part of history, I don't think it will be done again," Dettori told At The Races.
"Having three runners in the Arc is hard enough, but to have the one-two-three is beyond belief.
"My horse ran well, I would have preferred a bit more rain but he stuck his head out for me and galloped out to the line."
