Jockey William Buick admitted Adayar was a one-off after he rode the Derby hero to a brilliant follow-up victory in the King George VI and Queen Elizabeth Qipco Stakes at Ascot on Saturday.
Adayar became the first horse since Galileo 20 years ago to win both the Derby and the King George in the same year, overcoming the considerable challenge of rivals Mishriff and Love to take the prize in a thrilling showpiece race.
After Broome had made the early pace, Mishriff began to look like the one to beat as he came to the front but then Adayar suddenly took over, with Buick timing his run to perfection to win by a length-and-three-quarters in the end.
Mishriff had to settle for second, while Love was never really in contention in a disappointing third for the pre-race favourite.
Buick was lost for words afterwards as the three-year-old gave Charlie Appleby his first win in the big Ascot contest, although the Godolphin trainer wasn’t able to enjoy the race himself from the track as he had been pinged by the NHS app this week.
Buick told ITV: “I’m speechless to be honest. He gives you the feel of endless power and it’s a privilege to ride a horse like this because they don’t come around very often.”
Betfred now make Adayar 5/1 to win the Qatar Prix De L’Arc De Triomphe on October 3, behind Snowfall at 3/1. Appleby’s King George winner could also run in the St Leger at Doncaster on September 11 and is 2/1 to win the Classic.
