Trained by John Gosden, the son of Make Believe beat The Summit and Poule d'Essai des Poulains winner Victor Ludorum at Chantilly, settling the race in a matter of strides in the manner of an exciting horse.
"John's original plan was to go for the G2 at Deauville [Prix Guillaume d'Ornano, August 15] which a lot of the French Derby winners go to, but I know that the Prince was keen to consider the Juddmonte [August 19]," said the owner's racing manager Ted Voute.
"We will take a breather, let the horse come back to himself and then make a decision so that conversation hasn't really happened yet."
Voute added: "Mishriff is not sold – the Prince has refused all the offers and he is waiting to see what John feels. He is quite a personal horse to the Prince because he is named after a very good friend of his who died and he owns a third of the stallion as well."
Mishriff has won three of his six starts, breaking his maiden by ten lengths before taking the Newmarket Stakes in which he beat Volkan Star, who has since won a Listed and G3 race, by four lengths.
In between he showed he could be a potential 2021 Saudi Cup candidate for his Saudi owner when he contested the inaugural Saudi Derby, finishing second on the dirt to Japan's Full Flat after a slow start.
"Funnily enough the Saudi Cup was mentioned by the Prince," Voute said. "He ran very creditably out there so it should be on the radar. It would mean not retiring him to stud next year, but we will take things one step at a time working back from the Champion Stakes at the end of the year."
