Camelot features among the 22 confirmations for the 2000 Guineas at Newmarket on Saturday while Maybe is among 21 fillies left in the 1000 Guineas at Newmarket 24 hours later.
Camelot, the son of Montjeu, was a brilliant winner of last year’s Racing Post Trophy at Doncaster on just his second career start and he has headed the market for both the Guineas and the Investec Derby during the winter.
The Ballydoyle team have two other possible runners in Power and Furner’s Green.
Another fascinating contender for Ireland is the John Oxx-trained Born To Sea, a half-brother to the great Sea The Stars who won this in 2009 before going to win the Derby and the Arc.
Jim Bolger’s Parish Hall has arguably the strongest form in the race having won the Dewhurst Stakes at Newmarket last October, beating the likes of Power, Most Improved, Bronterre and Trumpet Major.
Richard Hannon has both Bronterre and Trumpet Major engaged in Saturday’s Classic.
Bronterre was beaten at odds-on in the Greenham Stakes at Newbury on his comeback, but Trumpet Major impressed in his trial, the Craven Stakes.
The champion trainer also has Coupe De Ville and Redact in the mix.
Roger Charlton is set to saddle his much talked about Newbury maiden winner Top Offer, while Abtaal, French Fifteen and Hermival are all contenders for France.
Other interesting possibles include Caspar Netscher, Boomerang Bob and Fencing.
The sole supplementary entry is the Jeremy Noseda-trained Talwar, an easy winner of a Lingfield Listed race last time.
Maybe, the daughter of Galileo, heads the 1000 Guineas market thanks to going through her juvenile campaign unbeaten.
She won five times, culminating in the Group One Moyglare Stud Stakes at the Curragh at the end of August.
Trainer Aidan O’Brien has three other possibles in Leopardstown 1,000 Guineas Trial winner Homecoming Queen, Up and Wonderful.
Lightening Pearl, winner of the Cheveley Park Stakes, could try to give Co Meath handler Ger Lyons Classic glory while the other Irish-trained entries are Jim Bolger’s Alla Speranza, David Wachmans’s Fire Lily and Kevin Prendergast’s La Collina.
Mashoora, winner of the Prix Imprudence at Maisons-Laffitte and trained by Jean-Claude Rouget, is the sole remaining French filly.
Godolphin have a strong hand in the shape of Discourse and Lyric Of Light, who both have 100% records for trainer Mahmood Al Zarooni.
Discourse won the Sweet Solera Stakes on the second of her two starts while Lyric Of Light’s three successes included the May Hill Stakes at Doncaster and the Shadwell Fillies’ Mile at Newmarket.
Also among the home contingent are Diala, Gray Pearl, Laugh Out Loud, Lily’s Angel, Nayarra, Radio Gaga, Starscope, Sunday Times and The Fugue.
The list is completed by Moonstone Magic, who has been supplemented by trainer Ralph Beckett.
Meanwhile, Henry Cecil plans to take Frankel for a racecourse gallop at Newmarket on Sunday as he builds towards his seasonal return.
The world’s highest-rated Flat horse suffered a leg injury earlier this month and for a brief period there were real concerns about the four-year-old’s future racing career.
A subsequent scan revealed the unbeaten nine-time winner had suffered no serious damage though, and he is now back in full work ahead of his likely return in the JLT Lockinge Stakes at Newbury on May 19.
The clash everyone wants to see this summer is Frankel versus the world’s second highest-rated racehorse, Australian wonder-mare Black Caviar.
Peter Moody’s six-year-old stretched her unbeaten record to 20 last weekend and is on course to run in the Diamond Jubilee Stakes at Royal Ascot in June.
However, the Sussex Stakes at Glorious Goodwood seemingly the only conceivable contest in which the pair could meet.
It is a battle Cecil would relish.
“She’s a brilliant filly, obviously, and so consistent,” said the trainer.
“I’d love to meet her. I would look forward to it.”
French ace Dunaden is one of the star names among 12 remaining entries for the Qatar Bloodstock Jockey Club Stakes at Newmarket on Saturday.
The Mikel Delzangles-trained six-year-old enjoyed a spectacular end to last season, winning the Geelong Cup and the Melbourne Cup in Australia before dashing to Sha Tin to collect the Hong Kong Vase.
Possibly joining him on the trip across the Channel this weekend is Andre Fabre’s Grand Prix de Paris winner Meandre, last seen finishing sixth in the Prix de l’Arc de Triomphe.
Another horse who has been off since that Longchamp contest, Masked Marvel, is another major contender for Saturday’s mile and a half Group Two.
Fiorente showed some decent form last year and is an interesting player making his four-year-old debut for Michael Stoute.
Al Kazeem, Blue Bajan, Eternal Heart, Highland Castle, Modun, Quest For Peace, Ed Dunlop’s Melbourne Cup runner-up Red Cadeaux and Sadeek’s Song complete the field.
