Owner-breeder Anthony Oppenheimer remains keen to give his stunning Prix de l'Arc de Triomphe winner Golden Horn one last hurrah in the Breeders' Cup Turf.
The John Gosden-trained colt, winner of the Epsom Derby, Coral-Eclipse and Irish Champion Stakes, benefited from a brilliantly-judged ride from Frankie Dettori to claim a momentous victory in the Longchamp showpiece on Sunday.
While he will not be kept in training as a four-year-old, a trip to Kentucky at the end of the month remains a distinct possibility.
"He is the most extraordinary horse. He has such adrenaline during his races but I went to see him afterwards and he was munching away on his feed without a care in the world," Oppenheimer said.
"The lads who look after him said you would honestly think he was just about to race, rather than having won the Arc already.
"We'll just have to see how he is as you don't really know how much the race has taken out of him for two or three days.
"I think we're fairly keen to go to the Breeders' Cup, but the horse has had such a good year, I don't want to push him too much.
"He definitely won't be back next year. I know some horses come back as four-year-olds if they have something to prove, but I honestly don't think we have anything to gain.
"After a fantastic year, I'm very happy as a breeder to send him to stud and looking forward to seeing his foals the following year."
Golden Horn will retire to Darley's Dalham Stud, with Oppenheimer retaining a half-share.
