Aidan O'Brien's unbeaten Diego Velazquez will take on seven rivals in this Saturday's Group 1 Futurity Trophy at Doncaster.

Aidan O'Brien will saddle two horses in his bid to record a record-extending twelfth Futurity Trophy, with Diego Velazquez seemingly his main hope of landing the final British Group 1 of the season.

The son of Frankel cost a staggering 2.4 million guineas as a yearling and quickly made a smart initial impression when winning at the Curragh on debut. Diego Velazquez took the step up the group level in his stride with a comfortable success over stablemate Capulet in the Group 2 KPMG Champions Juvenile Stakes at Leopardstown in September and is subsequently a general 7/4 shot to remain unbeaten this weekend.

Stablemate Battle Cry has also been confirmed to line-up on the Town Moor.

Impressive Group 3 Autumn Stakes winner Ancient Wisdom was supplemented earlier in the week and Charlie Appleby's son of Dubawi is now vying for favouritism after being declared to face the O'Brien duo at Doncaster.

Roger Teal's Dancing Gemini handled soft ground well when landing the Listed Flying Scotsman Stakes last month and will return to the scene of that authoritative victory now stepping up to a mile for the first time.

Fellow last-time-out Doncaster scorer God's Window will take the plunge straight into top-class company after creating a taking impression over course and distance on debut at the St Leger meeting last month. The runner-up that day, Redhot Whisper, will reoppose and give jockey Stefano Cherchi his first ride in a Group 1, whilst Devil's Point and Deira Mile complete the field of eight.
