Pathfork, now down to 5-1, is a solid each way shot. Trained by Jessica Harrington, he proved himself the leading juvenile in Ireland by completing a hat-trick in the Vincent O'Brien National Stakes at the Curragh.
The form was subsequently given a boost by the success of the runner-up, Casamento, in last October's Racing Post Trophy.
The grey Native Khan, generally a 12-1 shot, was undeniably impressive in landing the Craven Stakes at Newmarket earlier this month.
Yet you sense that only impatience or bad luck can prevent Frankel giving Henry Cecil an extraordinary 25th Classic success.
Precocious and talented in equal measure, he has had star quality from the moment he burst onto the racing scene last summer. Yes, at times, he has been far too keen for his own good, doing his best to wrench the arms of his jockey Tom Queally from their sockets on several occasions.
"The hardest part at Newbury was trying to pull him up after the line", said Queally after Frankel had romped home in the Greenham Stakes on April 16. In the paddock the horse with a huge following was impressively calm but on the course it was a different story when he found the early pace too pedestrian.
One moment he was apparently relaxed. The next he was tanking, restlessly eager go several strides faster than Queally wished.
One day his impatience may cost him dear. Let's hope it is not on Saturday.
