Aidan O’Brien in dreamland with Prix de l'Arc de Triomphe clean sweep

It may be one of the finest moments in Flat racing history.

Aidan O'Brien's mastery of the thoroughbred touched upon levels of genius at Chantilly on Sunday as Found led home a Ballydoyle clean sweep in the Prix de l'Arc de Triomphe.

Never one to extol his own virtues, even the quiet man from County Tipperary admitted that this achievement deep within the valley of the Nonette was probably his finest moment as a trainer.
