Dettori sweet on World rule

Frankie Dettori has given Ruler Of The World a ringing endorsement as the dust settles on his all-the-way success in the Prix Foy at Longchamp last weekend.

Winner of last year’s Investec Derby, the Aidan O’Brien-trained colt was having his first start since finishing down the field in the Dubai World Cup in March, and in doing so put his case for another crack at the Prix de l’Arc de Triomphe.

He was seventh in the all-aged middle-distance championship 12 months ago, and is a best-priced 16-1 to go a few places better back at the Paris track on October 5.
