AIDAN O’Brien has already saddled the winners of 22 Group 1 races this year and the champion trainer of Ireland and Britain has a great chance to end the year on a high at Sha Tin on Sunday.

Highland Reel, already the winner of the King George at Ascot and the Breeders’ Cup Turf at Santa Anita this season, is a hot favourite to repeat his success of last year in the 12-furlong Vase.
