Racing: Simon Holt of Channel 4 Racing analyses the Derby at Epsom this afternoon

Adair: Godolphin's second string following indifferent gallops. Easily won his only race in New York.

All The Way: Guaranteed stayer unsuited by soft ground. Beat Rhagaas at this trip last month.

Beat All: Quickened well to beat Italian Derby winner Mukhalif at Newmarket in April. Off since.

Brancaster: Stayed on into fourth in 2,000 Guineas and could improve over this longer trip.

Compton Admiral: Beat Brancaster over 1m but flopped in Guineas. Bred to be suited by trip.

Daliapour: Easy winner here (1m 2f) in April and then second to Lucido at Lingfield. Likes soft.

Dubai Millennium: Unbeaten in three starts and sprinted from last to first in a few strides to win at Goodwood. Working well since.

Glamis: Has not fulfilled promise and only seventh to Salford Express in Dante Stakes at York.

Housemaster: Won Chester Vase but disqualified for causing interference. Guaranteed stayer.

Lucido: Supplemented at cost of pounds 75,000 having earlier looked below this standard. Has beaten Oath and Daliapour. Big chance.

Oath: Beaten fair and square by Lucido in April (may have needed race) but looked improved in five-length win in Dee Stakes. No doubts on ground or stamina.

Rhagaas: Carried his head high when no match for All The Way at Newmarket in early May.

Saffron Walden: Unbeaten this season, winning Irish 2,000 Guineas last time. Top class but big doubts about him staying 1m 4f.

Salford Express: Fine win in Dante and progressive. Trainer not to be under-estimated.

Tchaikovsky: Goes well on soft but easily beaten at Leopardstown last time - not Derby form.

Through The Rye: Fourth to Oath at Chester. No chance.

Val Royal: Unbeaten. Successful twice over 1m 1f this season but not certain to stay much further.

Zaajer: Outside chance following defeat of Italian Derby winner (1m 2f). Needs soft ground.

Conclusion: Despite stamina doubts, DUBAI MILLENNIUM can give Frankie Dettori a first Derby success. He has most to fear from much improved Oath.
