"He's probably the closest thing we've likened to Hitotsu in terms of his racing style.
"He's probably not as dynamic, but his ability to be winning a Derby and coming back to be a Group 1 mile Guineas winner at his next preparation is hard to do.

"The main thing with him is getting him to relax and settle. That meant having to go down to the fence and riding a cool, patient race on him.
"From there on in, the track is fair, we stuck to the fence and he did the rest.
"He's a superstar."
