Dettori vies for world rule in Arc

One more piece of the Prix de l’Arc de Triomphe jigsaw slotted into place on Wednesday when Frankie Dettori was confirmed as the rider of Ruler Of The World.

It had been feared the Italian, who missed the winning mount on Treve 12 months ago at Longchamp and has been replaced on the filly by Thierry Jarnet, would be forced to watch from the sidelines once again this Sunday.
