Spotlight: By Dubawi out of a much admired mare who won 13 races, including six Grade/Group 1s at up to about 1m, and who has bred a 1m6f Group 1 winner; became well seasoned during a 2yo career which ended with a hard-fought second in the Group 1 Futurity at Doncaster (1m, soft) and has returned with two Group 3 wins at Leopardstown (1m2f; on good to yielding and good), the former from Lambourn and announcing new depths in the latter; still improving and he won't mind what the weather does.

Spotlight: Granddam's siblings include Brian Boru, whose two Group 1 wins included the 1m6f St Leger, and Sea Moon, a dual Group 2 winner at 1m4f; never more impressive than in the final furlong when winning a 1m maiden at Sandown (good; unraced on slower) on sole 2yo start and his finish was deadly again in the Group 2 Dante at York (about 1m2f, good to firm) when, despite having little space and taking a few strides to pick up, he dashed clear of Damysus in a matter of strides; this will be more truly run but he's making big waves and there's no knowing how far he can go.

Spotlight: By Justify, who sired last year's Derby winner, out of mare by another who won this race; he lost nothing in defeat to a sharper type in The Lion In Winter over 7f at York on final 2yo start and, following a spreadeagling win at Meydan, came from off the pace to take the 2,000 Guineas at Newmarket (1m, good) in May; now goes into the blue yonder stamina-wise but his trainer seemed quite bullish about his Derby prospects immediately after the Guineas; out of the top drawer already and may well enhance his reputation today.

Spotlight: Out of a smart sprinter but it's stamina that he's inherited from his Derby-winning sire Australia and, following a French Listed win (1m, very soft) last year and a second to Delacroix at Leopardstown in March, he sent out a strong staying message when beating Lazy Griff in the Group 3 Chester Vase (about 1m4f, good) last month; his potential at 1m4f+ is clear but the tactical speed, on the Chester run, is less so at this stage.

Spotlight: Bred for middle distances but he was the sharpest tool in the box when having Ruling Court back in third in a 7f Group 3 at York (good to firm) in August on final 2yo start; inconclusive reappearance in Group 2 Dante at York in May, when he wanted to tear off early before plugging on at one pace when the cause was lost; however, he was said to be only just ready for that return and he did run a lot better there than the last two Derby winners from this yard had on their comebacks; some second-guessing is needed about the trip but he can't be ruled out with confidence.

Spotlight: Made debut in March and is unbeaten in three starts; there was much to like about the way he raced, settling nicely and responding willingly, when making all on the promotion to Group 3 level at Saint-Cloud (about 1m2f, good; has also won on good to soft) last month; has been supplemented in honour of his owner/breeder, the late Aga Khan, after whom this Derby is named; something of an unknown quantity but his dam was a stayer and hopefully he will reward his famous connections with a great run.

Spotlight: 460,000gns yearling; by Frankel out of a Group 2/3 winner at 1m4f; won a 7f AW novice on sole 2yo start and he's been coming into his own over more suitable distances this year; did not get the best of trips when second to Pride Of Arras in the Group 2 Dante at York (about 1m2f, good to firm) last time, being caught out wide in the straight, well apart from the winner, but putting plenty of beef into his finish; has worked pleasingly at Epsom since and should be right at home over the new trip.

Spotlight: Dam's winning siblings include Romsdal, placed in the Derby and St Leger; dug in late for a promising third to Ruling Court on Sandown 7f debut as 2yo and ended the season by making Delacroix pull out most of the stops in a Newmarket Group 3 (1m, good to soft); had a gift of a reappearance at Salisbury recently but if he's made the same progress over the winter as some of his rivals he'd be on the premises.

Spotlight: Out of half-sister to top-class miler Rock Of Gibraltar; upgraded his 2yo form when dealing with heavy ground to beat Green Storm in a three-runner race for Group 1 Criterium de Saint-Cloud (1m2f) in October; the race looked to be needed when he was beaten nearly 7l by Delacroix in a Group 3 at Leopardstown (1m2f, good) last month but that's quite a gap to bridge.

Spotlight: Frankel colt whose dam never won beyond 6f but she bred a dual Grade 1 winner at 1m1f and her high-class siblings, including St Leger winner Logician, weren't short of staying power; he didn't have the clout for the Group 3 at Newmarket (1m, good to soft) won by Delacroix from Stanhope Gardens in October, for Sir Michael Stoute, but he was always likely to make a better 3yo; this might come too soon in his career but he was one of a few to come home strongly in the Group 2 Dante at York (about 1m2f, good to firm); now has cheekpieces fitted; the best is yet to come.

Spotlight: Out of a Group 3 winner at about 1m2f whose dam's wins included one over 1m6f; 2-2 as a 2yo and he's finished a close third in both starts this year, the reappearance in a Group 3 at Longchamp (1m1f, good) working out well; a Listed defeat since shows he has to rely heavily on improvement for the longer trip if he's to make his way in this company; has been supplemented.

Spotlight: Dam's winners include Just Fine, who won an Australian Group 1 at 1m4f; a low-profile 2yo career ended with a 1m AW maiden win but he led for a long way in the 2,000 Guineas at Newmarket and did well to head the pack behind the first three; he was said to be only 80% ready, so improvement can be expected but it's unlikely to be enough for him to take a hand today.

Spotlight: Sizeable advance in form when making all in a Group 3 at Chantilly (1m1f, good) on final 2yo start and he looked to have gone the right way over the winter on reappearance in Group 3 Chester Vase (about 1m4f, good) when it wasn't a breeze for Lambourn to get past him; aims much higher now, though.

Spotlight: All three runs in maidens and he made all at Chester (1m4f, good) in May; low on the list in form terms but his owner, who also runs Green Storm, has had big-priced runners finish in the frame in recent Derbys, including for this yard last year, and this could be another surprise package.

Spotlight: Dam won five Group races at up to 1m4f and was touched off in the Irish Oaks; six 2yo runs yielded one win at 1m1f before seconds in Group races over 1m2f at Newmarket (good to soft) and Saint-Cloud (heavy); this new trip should suit but he dropped right out at Newmarket (1m1f) in April.

Spotlight: Tough display when winning a 1m4f novice on AW on return; however, he couldn't hang on to the first two in the Listed Lingfield Derby Trial (extended 1m3f, good to firm) and is down this pecking order.

Spotlight: Granddam is Oaks winner Eswarah; 2-2 as 2yo, latterly in a Listed race on soft, and ran as well as could have been expected when seventh in the Dante at York on his needed comeback; the bar is much higher here.

Spotlight: Pedigree has links to Derby and Oaks success; tenacious winner of the Listed Trial here (1m2f, good) in April but Group 1 aspirations are on hold after he finished down the field in the Dante (about 1m2f, good) at York.

Spotlight: Well related but he didn't improve much from a 1m4f AW maiden win over Al Wasl Storm in April when looking out of his depth in the Lingfield Derby Trial (extended 1m3f, good to firm); a similar outcome is likely today.
