O’Brien remains confident of Yeats’ class in top middle distance events

AIDAN O’Brien is confident Yeats would have more than enough class to hold his own in some of this season’s premier middle-distance events.

The eight-year-old made history at Royal Ascot last week when becoming the first horse to win the Gold Cup four times.

Such was the manner of his success that connections have spoken about possible tilts at the King George VI & Queen Elizabeth Stakes and the Prix de l’Arc de Triomphe at Longchamp later this year.
