Classic-winning colts Gleneagles and Golden Horn are among a stellar 42-strong entry for the Juddmonte International at York on August 19.
The Aidan O'Brien-trained Gleneagles, who completed the English and Irish 2000 Guineas double, could step up in trip to a mile and a quarter first in the Coral-Eclipse at Sandown next month.
O'Brien has a total of 14 entries - Cougar Mountain, Tapestry, Father Christmas, Giovanni Canaletto, Highland Reel, John F Kennedy, Kilimanjaro, Ol' Man River, Diamondsandrubies, Found, Qualify, Together Forever and Words.
Investec Derby hero Golden Horn, who is a probable for the Eclipse, heads a powerful team from the John Gosden stable. The Newmarket trainer's four other possibles are Eagle Top, Mahsoob, Maverick Wave and Western Hymn.
David Wachman's 1,000 Guineas winner Legatissimo could also represent the Classic generation.
The Grey Gatsby, runner-up to Australia in this race 12 months ago, is likely to try to go one better for North Yorkshire trainer Kevin Ryan.
Dermot Weld's Free Eagle, who just pipped The Grey Gatsby in the Prince of Wales's Stakes at Royal Ascot last week, is an interesting contender as is Australian raider, Criterion, who was back in fifth that day.
The O'Brien pair of Investec Oaks winner Qualify and last year's winner Tapestry also feature among 43 entries for the Darley Yorkshire Oaks on August 20.
Among 53 entries for the Coolmore Nunthorpe Stakes over York's fast five furlongs on August 21 are Eddie Lynam's dual winner Sole Power and Goldream, successful in the King's Stand Stakes at Royal Ascot last week.
