Kalaman and Trade Fair top Sussex market
The pair, trained by Sir Michael Stoute and Roger Charlton respectively, are the joint market leaders at 2-1 with Coral for the mile event, while William Hill have Kalaman as the clear 13-8 favourite.
Kalaman is one of 11 horses declared for the race and he will be bidding to go one place better than his runner-up spot in the St James's Palace Stakes at Royal Ascot.
He finished one length adrift of Zafeen that day and the pair will clash again on the Sussex downs.
Zafeen, who is trained by Mick Channon, is reported to be in top condition ahead of the race, where he will be bidding for a second Group One victory.
The Zafonic colt was runner-up to Refuse To Bend in the Sagitta 2000 Guineas before disappointing in the Irish equivalent on soft ground at the end of May.
He bounced back to form at Ascot and Joe Mercer, racing manager to owner Jaber Abdullah, is hopeful of a good run.
"He's in great form," he said. "We're just hoping the ground won't be too soft as he likes good, fast ground. But it sounds like the going will be good.
"He really doesn't like the soft ground, as he showed in Ireland when he saw too much daylight and ran a dismal race.
"He ran a tremendous race at Ascot, though, and we are expecting a good run. He should have a very good chance."
Many pundits thought Kalaman was an unlucky loser at the Royal meeting as he did not get a clear run in the race, but Mercer believes Zafeen will be thereabouts again.
"I know a lot of people thought he was a trifle unlucky at Ascot but he won well, kicked at the right time and although the ground suited us, he did it well," he added.
"Obviously Kalaman would have a chance it's a good race."
Trade Fair commands his position in the market on the back of an impressive win in the Group Three Betfair Criterion Stakes over seven furlongs at Newmarket last time and the trio are the leading contenders from the six three-year-olds who run.
Aidan O'Brien will be double-handed with both Spartacus and Statue Of Liberty declared, while Norse Dancer, who disappointed last time for trainer David Elsworth in the Coral-Eclipse Stakes, completes the three-year-old contingent.
Dubai World Cup winner Moon Ballad takes a step down in trip and is one of two runners for Godolphin in the Group One event, with Blatant also lining up.
Former top South African horse Eventuail represents William Haggas, while Terry Mills fields last year's Queen Elizabeth II Stakes winner Where Or When.
The latter met Hawk Wing at the top of his game when a distant second in the Juddmonte Lockinge Stakes.
