Meanwhile, Dermot Weld is considering an ambitious tilt at the Prix de l’Arc de Triomphe in October with high-class mare Zhukova.
The daughter of Fastnet Rock won her first three starts of last season, but disappointed when stepped up to the highest level in the British Champions Fillies & Mares Stakes at Ascot in October.
She righted that wrong with a stunning display in the Grade One Man O’War Stakes at Belmont Park in May, and was last seen finishing a creditable fourth in the Pretty Polly Stakes at the Curragh.
“She put up a spectacular performance when she won the Man O’War for us and we’re delighted with her,” said Weld.
“She’s in great order and we’ll speak with her owner and decide whether we train her for the Arc or go back to Belmont for the Turf Classic and then races like the Canadian International. All those great races are there in the fall for her. If I thought we were going to get a wet autumn, we’d definitely train her for the Arc.”
