Flintshire leads a possible field of 13 for Sunday's Qatar Prix Niel, one of the highlights of Arc trials day at Longchamp.
Andre Fabre's charge emerged as a leading candidate for the Prix de l'Arc de Triomphe after winning the Grand Prix de Paris back in July, supplementing an earlier win in a Chantilly Group Three.
He is one of five possibles for Fabre with Epsom Derby fifth Ocovango, Penglai Pavilion, Vancouverite and Triple Threat all still in the running.
Japanese Derby winner Kizuna is unbeaten in his last three starts but would seem likely to need the race having been off the track since his Classic success at the end of May.
Aidan O'Brien's Epsom winner Ruler Of The World is entered at this stage after managing to finish only fifth in the Irish Derby on his latest start.
Alain de Royer-Dupre is double-handed with Manndawi and Shirkapour while Pascal Bary also has a couple of contenders in Preempt and Spirit Jim.
Max Dynamite, and Bravodino also feature.
Last year's unlucky Arc second, the Japanese runner Orfevre, is set to get his European campaign rolling in the Prix Foy.
The Group Two race for older horses features Aidan O’Brien’s dual Derby winner Camelot, while 2011 Melbourne Cup winner Dunaden could represent Mikel Delzangles.
O'Brien also has Chamonix in the race, while Ed Dunlop could saddle Joshua Tree.
Mandour, Very Nice Name, Now We Can, Stellar Wind, Going Somewhere, Haya Land and Pirika also feature on the 12-strong list.
The Qatar Prix Vermeille counts this year's impressive French Oaks winner Treve among 16 contenders for Group One glory.
Silasol finished third that day and could try her luck again, while O'Brien's Irish and Yorkshire Oaks second Venus De Milo could have another shot at the highest level.
Jane Cecil's pair of Wild Coco and Hot Snap are among the possibles, although both hold alternate engagements, as does Michael Bell's The Lark.
Ralph Beckett has left in Epsom heroine Talent, although she could tackle the Ladbrokes St Leger 24 hours earlier.
German Oaks winner Penelopa is another eyecatching entry along with Fabre's Prix Jean Romanet winner Romantica.
