Dylan Thomas: The world's highest-rated active turf horse; Europe's Horse of the Year and Leading Older Horse of 2007; also the highest-rated horse ever to appear in Hong Kong; six Group 1 successes, including the Prix de l'Arc de Triomphe in October; last year's Irish Derby and a four-length cruise in the King George in July. In September became the first horse to achieve successive victories in the Irish Champion Stakes. Quijano: Successful in the Group 1 Grosser Preis von Baden in September and has since ran a close third in the Canadian International. Hit the headlines by winning 10 consecutive races - seven in Germany and three in Dubai over 2,400m - although the sequence ground to a halt when midfield behind Vengeance Of Rain in his first Group 1 assignment, the Sheema Classic. Red Rocks: Last year's Breeders' Cup Turf champion on fast ground but has since met with mixed fortunes. Well behind when ninth to Vengeance Of Rain in Dubai, but bounced back to take a Group 3 over 2,000m next start. Never dangerous when fourth in two subsequent Group 1s and a distant third in Breeders' Cup. Doctor Dino: In the frame in all five Group 1 starts this year with a highlight win in the Man O' War Stakes (Group 1 - 2,200m) in New York in September. Highly commendable third in Group 1s to Dylan Thomas in Paris, Shadow Gate in Singapore and Literato in the Champion Stakes at Newmarket (badly hampered 400m out). Unraced beyond 2,200m but shouldn't have any trouble over Sha Tin's easy 12 furlongs. Bussoni: Thorough stayer; made all for two-length victory from Group 1 winners in the 2,400m Bosphorus Cup in September. Previously successful over longer trip (2,800m) in a Group 2 in France (made all, rival Macleya two lengths behind when third) and a Group 3 over 3,200m in Germany. Has finished third and fourth in his Group 1 forays and he needs to lift to figure here. Egerton: Perennial Group 1 bridesmaid; never better than midfield when four length back in sixth of nine runners in this race last year when he arrived in Hong Kong zero-for-eight in Group 1 races. That losing run at the highest level now extends to 14 defeats after a year when his only successes came in two Group 3 events in Germany. Vital King: Gave everything to secure victory by a nose in the Hong Kong Derby last season from Floral Pegasus and no surprise he was spelled after midfield finish (beaten five lengths by Viva Pataca) in the QEII Cup (Group 1 - 2,000m). Has been prepared for this race and caught the eye when fourth in the Cup Trial to indicate the first-time advance from 2,000m should suit. Arch Rebel: Durable, high-class six-year-old; former hurdler; nearly secured a career highlight when a nose second to Group 1 winner Montare in Prix du Conseil de Paris (Group 2 - 2,400m) last start; consistent performer but just two wins in most recent 16 starts (mostly Listed and Group 3 level). Started at 66-1 for sole Group 1 attempt in Ireland when held 11 lengths. Best on rain-affected tracks. Kocab: Consistent four-time Listed winner facing a first Group 1 assignment on his 10th start of the year. Looked the winner when hitting the front 350m out in the Prix du Conseil de Paris (Group 2 - 2,400m) but faded to finish one length behind rival Arch Rebel. Also ran second to Cup runner Musical Way in a Group 3 down the straight at Maisons-Laffitte. Viva Macau: Imported to Hong Kong last season with Classic ambitions but could only finish ninth in the Derby after a wide trip. Ran second in the Classic Mile and Derby Trial. Well beaten both tries at this trip. including third in the Champions & Chater. Recorded first win in a handicap on penultimate start but found out again at set weights when sixth in the Cup Trial. Hawkes Bay: Last month's handicap winner from a big weight over 1,800m and open to further improvement but there are class and stamina queries. Well beaten on his only previous Pattern experience in the 2006 Hong Kong Derby Trial and untried beyond 1,800m. Ever Bright: Talented, hardy stayer; admirably returned from a pelvic fracture to win four straight last season, culminating with the Queen Mother Memorial Cup (Group 3) at this distance. Had excuses when trapped wide in both starts this term. Yet to tackle a Group 1 field and up against it on official ratings. Macleya: Versatile French mare with a fine record in Group races from 2,000m to 3,200m this year; landed Group 3 and Group 2 races for females earlier in the season and no shame when fifth in the Group 1 Prix Vermeille penultimate start.
