Sobetsu is set to make a third trip to France for the Prix de l'Opera.
Having tasted Group One glory at Deauville in May, the daughter of Dubawi bounced back from defeats in the Epsom Oaks and Nassau Stakes with victory in a Group Two back at the seaside venue.
Charlie Appleby, her trainer, said: "I'd say that she will go back to France for the Opera. She has been invited to the Queen Elizabeth Challenge Stakes at Keeneland and I am not completely ruling that out.
"We have got Wuheida there for that. If you put a gun to my head right now, I would say Sobetsu would go for the Opera as she is likely to get her ground out there." Appleby is leaning towards sending Wild Illusion to Doncaster for a shot at the May Hill Stakes.
The Newmarket handler is favouring an outing in the mile Group Two prize for the daughter of Dubawi, who also holds top-level entries in the Moyglare Stud Stakes and the Fillies' Mile, following her taking debut success at Yarmouth.
Appleby said: "I was pleased with Wild Illusion's performance at Yarmouth as there were a couple of other well-thought-of horses in there and I thought it was a nice enough maiden."
He added: "She is a filly for next year, but she does have a few lofty entries. She seems to have come out of the race well
"I think we will let the dust settle and work back from the May Hill. I would like to find a stepping stone before the May Hill, but if there is no logical step we will might look at taking her straight there."
