Aidan O’Brien has four runners in French Derby

Aidan O’Brien fires a four-pronged assault in a bid to win Sunday’s Prix du Jockey Club for the first time.

The Ballydoyle handler’s Chantilly quartet is headed by Rostropovich, who ran out an impressive winner of the Dee Stakes at Chester on his latest appearance and heads for France instead of running in the Investec Derby at Epsom the previous day.

Rostropovich was handed stall three in the official live draw and will be ridden by Ryan Moore.

O’Brien also saddles Hunting Horn (14) and Flag Of Honour (12), who were third and fifth respectively in the Chester Vase, as well as Kenya (two), who was last of seven behind Rostropovich on the Roodee.

The British challenge is spearheaded by the James Tate-trained Hey Gaman (13), who gets his second shot at French Classic glory after finishing a narrow second behind Jean-Claude Rouget’s Olmedo in the French 2000 Guineas – the Poule d’Essai des Poulains. James Doyle is on board.

Key Victory (seven), the mount of William Buick, was supplemented by Charlie Appleby and Godolphin following his victory in the Newmarket Stakes at the start of May.

Olmedo heads the home team and will break from stall one.

Prix Greffulhe winner Study Of Man (six) also appears well drawn in an 18-strong field.
