Aidan O'Brien and John Gosden are doubly represented in the Betfred Dante Stakes at York on Thursday.
O'Brien sends James Cook and Zabriskie across the Irish Sea in his bid to win this recognised Derby trial for a fifth time, but both horses need to improve after finishing down the field in the Investec Blue Riband Trial at Epsom last month.
Gosden appears to hold stronger claims, with his Epsom trial winner Crossed Baton joined by stablemate and likely favourite Roaring Lion, who steps up in distance after finishing fifth in the 2000 Guineas.
Wells Farhh Go is unbeaten in two starts at York and would be a popular winner for Yorkshireman Tim Easterby.
Mark Johnston struck gold with Permian 12 months ago and has another live Dante contender in Feilden Stakes winner Mildenberger.
David Elsworth's Merlin Magic, the Charlie Appleby-trained Nordic Lights and White Mocha from Hugo Palmer's yard complete the nine-strong field.
Coronet and Mori, respective first and second in the Ribblesdale at Royal Ascot, will meet again in the Betfred Middleton Stakes on the same card.
John Gosden's Coronet went on to run good races in the Yorkshire Oaks, the St Leger and back at Ascot on Champions Day.
Sir Michael Stoute's Mori, by Frankel out of Midday, did not progress after Royal Ascot in two outings but she returns having had wind surgery.
Stoute also runs Smart Call, top class in South Africa a few years ago but her career in Europe has yet to really take off.
Jim Bolger sends over Turret Rocks from Ireland, while Henry Candy's Chain Of Daisies has her first start in Group Two company.
Andrew Balding's Horseplay and Ed Walker's Indian Blessing complete the field.
