"Nayef is one of the toughest and most genuine horses I have ever come across. He really is an outstanding athlete, beautifully balanced and thoroughly consistent."Nayef's other group I wins came in last year's Juddmonte International and the 2001 Dubai Champion Stakes, also in England. He was England's champion 3-year-old male at 9 1/2 to 11 furlongs in 2001, and was a champion in Dubai the following year.. Nayef's fee will be announced at a later date.
