John O'Shea named as head trainer of Darley Australia in 2014 Darley has finally named a replacement for the departing Peter Snowden and have announced that John O'Shea will replace him as head trainer of Darley Australia in 2014. O'Shea's appointment came as little surprise with his name closely linked to Darley in the weeks since Snowden announced that he and son Paul would leave the Australian arm of Sheikh Mohammed's global racing empire early next year, with O'Shea all but a done deal a fortnight ago. O'Shea has enjoyed much success in the last decade and has trained ten individual Group 1 winners including Foxwedge, Sea Siren, Private Steer, and Racing To Win. He takes over a two-state, three-stable operation and more than 200 horses currently on the books at Darley.
