Epsom Derby: Joint-favourite Cracksman leads way for John Gosden

Jockey Frankie Dettori will ride Cracksman on the 10th anniversary of his first Derby win

Trainer John Gosden hopes joint favourite Cracksman will emerge as a "diamond" on Saturday in what he says will be a "terribly open" Epsom Derby.

Cracksman is one of five runners for Newmarket-based Gosden, who teams up with Frankie Dettori again after victory in the Oaks with Enable.

Gosden also runs Crowned Eagle, Glencadam Glory, Pealer and Khalidi, while Aidan O'Brien has six runners.

Derby outsider Diore Lia was ruled out on Saturday after pulling a muscle.

Apprentice jockey Paddy Pilley was to ride Diore Lia after Gina Mangan was barred from riding the 500-1 shot by the British Horseracing Authority (BHA) on Wednesday when they deemed her too "inexperienced".

Victory for Cracksman would seal Gosden a third Derby success, after Benny The Dip in 1997 and Golden Horn two years ago.

The son of Frankel won his only start as a juvenile at Newmarket and then beat fellow Derby contender Permian in a trial at Epsom in April.

"Cracksman has pleased me a lot, but he's light on experience," Gosden said.

"We'll probably find a champion at the end of it, but at the moment no-one can quite find that diamond in the rough.

"We like this horse a lot, but he is a different type altogether to Golden Horn, who was a very strong favourite."

Dettori said: "He is not Golden Horn by any means, but potentially he could be anything on Saturday and we will find out."

Moore to ride joint favourite Cliffs Of Moher

O'Brien, who has saddled five previous winners of the race but had to settle for second in the Oaks with hot favourite Rhododendron, has Dee Stakes winner Cliffs Of Moher leading his team.

Two-time Derby winner Ryan Moore will ride the current 4-1 joint favourite.

"Cliffs Of Moher was a little bit slowly away [at Chester] and Ryan got him into a good position fairly quick," O'Brien said.

"He's a horse that always showed plenty of pace, so we weren't even sure about going up to a mile and a half, but he galloped out well to the line at Chester."

O'Brien's daughter Ana will ride his three-year-old colt The Anvil to become only the third female jockey to ever race in the Derby.

Another of O'Brien's horses, Finn McCool, was the only withdrawal at the final declaration stage.

The total purse is set to be £1.625m, the richest race ever staged in Britain, with the winner receiving £920,913 and prize money then paid down to sixth place, which will net £21,922.
