"He just has an unbelievable amount of natural ability," trainer Aidan O'Brien told British television's Channel 4.
"To watch him he always quickens your heart. He's a very dangerous type of horse because he can make you say stuff ... as everybody saw last year and, as I've learned recently, you have to be very careful.
"If I blow up a horse too much because I believe it, the horse can pay the penalty. This is the sort of horse that can do that but he has the ability to go with it." Hawk Wing is likely to race next at Royal Ascot in the 10-furlong Prince of Wales' Stakes or the one-mile Queen Anne Stakes.
O'Brien's colt won an Eclipse at 3, but finish second in the 2,000 Guineas, Derby, Irish Champion Stakes and Queen Elizabeth II Stakes.
"Last year circumstances went against him in the spring and then, maybe because of that, he got little problems through the year," said O'Brien.
"Through the winter, there were problems that we had to sort out with muscles and things that everybody said might have niggled him for a long time. This year, he has been working like a dream."
