Vadeni is aiming to become the first French-trained winner of the Coral-Eclipse Stakes in over 60 years after being supplemented for Saturday's Group 1 showpiece.
At a cost of £50,000, the colt, owned by the Aga Khan and trained by Jean-Claude Rouget, was added to the Sandown field. The five-length winner of the Prix du Jockey Club at Chantilly is 13-8 favourite for his next big assignment, with Irish 2,000 Guineas hero Native Trail next in the betting at 7-2.
The last French-trained horse to win the Eclipse was the Alec Head-trained Saint Crespin in 1959, although very few have tried since the turn of the century. The last Aga Khan-owned runner in Sandown's big race was Diamond Green in 2005. He was partnered by Christophe Soumillion, who will ride Vadeni this weekend.
