At stud, Roberto sired many important winners including Sunshine Forever, Real Shadai, At Talaq, Touching Wood, Lear Fan, Kris S. and Dynaformer.
[4] The colt was owned throughout his racing career by the American businessman Richard L. Duchossois and was trained by Luca Cumani at the Bedford House stable in Newmarket.
On his final appearance of the season he was brought back in distance and matched against older horses in the Champion Stakes over ten furlongs at Newmarket on 18 October.
The result was only confirmed after the racecourse stewards failed to sustain an objection by Cochrane, who alleged that the winner had caused interference to the runner-up in the closing stages.
[7] Problems with the tendons in his right foreleg meant that Celestial Storm did not appear as a four-year-old until the July meeting at Newmarket where he started the 13/8 favourite for the Princess of Wales's stakes over one and a half miles.
Eighteen days later, Celestial Storm ran in Britain's most prestigious weight-for-age race, the King George VI and Queen Elizabeth Stakes.
Celestial Storm was never able to challenge Reference Point, who won by three lengths but was second best on the day, wearing down Triptych in the straight to take the runner-up's prize by a neck.
[9] In the official International Classification for 1986, Celestial Storm was rated the fifth-best three-year-old colt in Europe (behind Dancing Brave, Shahrastani, Bering and Last Tycoon) and the eighth-best horse of any age.
