Six time winner Andre Fabre brings Wind Chimes and Plumatic to represent him this year.
Wind Chimes was simply unlucky to have lost out to Teppal in the Poule d'Essai des Pouliches on her second outing this year.
She has also won the Gr.3 Prix de Lieurey at Deauville last time by three and a half lengths from subsequent listed winner Poetic Charm.
Plumatic also shows great potential.
They go head to head with Recoletos, who won four of his seven starts last season, including beating Plumatic by a nose in a Group Three feature at Maisons-Laffitte a year ago.
Recoletos was beaten by just two and a half lengths by superstar filly Alpha Centauri in the Prix Jacques le Marois at Deauville last time. With stablemate Oriental likely to help force a strong pace which will suit, a bold bid looks assured.
This year's challenge is led by Lightning Spear who renews rivalry with Sussex Stakes runner-up Expert Eye. He is yet to win over this trip
Intellogent was sixth in the Jacques le Marois, failing to reproduce the level of form he'd shown when winning the Prix Jean Prat on his previous start. Wootton also needs to bounce back, but he ran too badly to be true in the Prix Maurice de Gheest at Deauville last time. He's better judged on his previous form, which includes a close-up fourth in the Poule d'Essai des Poulains and an unlucky-in-running third to Without Parole in the St James's Palace at Royal Ascot. Better is expected from the Godolphin runner.
The lightly-raced three-year-old filly Homerique was a neck third to Laurens after being supplemented for the Prix de Diane at Chantilly in June, and didn't need to be at her best to gain a deserved win in a modest Group 3 at Deauville last time. She'll need to improve to feature here, especially now dropped back in trip.
Without Parole and Hey Gaman are other smart challengers who make this field a very interesting one.
Recoletos seems to be the best in-form horse in this field. He was an impressive winner of the Prix d'Ispahan the last time he teamed up with his pacemaker Oriental.
