Monsun has produced an impressive 17.5 per cent stakes winner to runners, with 65 group winners - 22 of them at group one level - and 112 stakes winners.
Vadamos was one of his very best and he won the group one Prix du Moulin at Longchamp, the group two Prix du Muguet at Saint Cloud, the group two Oettingen-Rennen at Baden and the group three Prix Messidor at Maisons-Laffitte from the stable of leading international trainer Andre Fabre.
"Vadamos always impressed me with his raw talent," said Fabre, who has prepared 180 group one winners.
"It is well documented that no other horse in my yard could beat him in the mornings and his final 200m time in the Moulin of 10.47s is absolutely top-class."
Vadamos, who will stand the Northern Hemisphere season at Tally Ho Stud in Ireland, won eight races from 1600 to 2400m and he ended his career with fourth placings in both the Cox Plate and the Emirates Stakes.
"To get this son of Monsun is unbelievable," Thompson said. "He's from one of the Aga Khan's great families and he's one of the best bred group one winning stallions going to stud anywhere in the world."
Vadamos is out of the Peintre Celebre mare Celebre Vadala, a half-sister to the group one winner Valixir.
"Sir Peter Vela, of Pencarrow Stud, Greg Tomlinson, of Nearco Stud, and Valachi Downs' Kevin Hickman are the key people in the syndicate and we've joined them with John Camilleri, of Sydney, who bred Winx and Vancouver, and Andreas Putsch, of Haras de Saint Pair in France, who both raced Vadamos," Thompson said.
