European stayer Royal Diamond will be trained by John Sadler with next year’s Sydney Cup (3200m) the main target for the nine-year-old.

The son of King’s Best was one of two horses - along with Mutual Regard - brought to Australia by trainer Johnny Murtagh to target the $6.2 million Emirates Melbourne Cup (3200m), in which he failed to handle the firm track and finished 20th.

Sadler said the horse would head back to England long-term but he was asked by the owners to prepare the horse for the Sydney Cup which is now worth $1.6 million.

“He’s having a break at Aquanita’s property Stonehedge Park in Drysdale and he’ll come back in work in probably around four week’s time to get ready for the Sydney Cup,” Sadler said.

“Some cut in the ground would make a big difference for him so hopefully he’ll be suited in Sydney during the autumn.”

Sadler said he would also pre-train six-year-old Mutual Regard, who finished 14th in the Melbourne Cup, in order to get him ready for the Dubai World Cup meeting in March.

“Mutual Regard has also gone to spell at Stonehedge Park,” he said.

“The idea of that was rather than have him go back to Ireland, have a break and then get ready over there, the owners thought they’d leave him in Australia and go straight from Australia to Dubai.”
