O'Brien and Cumani target Melbourne Cup

Aidan O'Brien and Luca Cumani have vowed they will return to Australia for the Melbourne Cup next year after their representatives lost little in defeat behind Efficient on Tuesday.

The winner did not grab Cumani's Purple Moon until the final 50 metres of the race, while Mahler finished third after sitting just outside pacesetter Tungsten Strike, who dropped out to finish last.
