Godolphin’s Rio De La Plata, who was only beaten by New Approach in the best juvenile event of the season in the National Stakes, could possibly be seen again this season after confirming his star quality by running away with the Prix Jean-Luc Lagardere at Longchamp.
Frankie Dettori was travelling so well in the final furlong he could even take a pull before unleashing the 8-13 favourite to sprint well clear.
He now firmly re-enters the shake-up for the 2000 Guineas and could yet be seen again this autumn.
Godolphin racing manager Simon Crisford said: “We’ll see what Sheikh Mohammed wants to do.
“He is in the Dewhurst but that is only two weeks away so it might come a bit quick for him, but he takes his races so well we’ll reserve that judgement for a while.
“He’ll certainly get a mile and a quarter (next year) as he’s so switched off. Whether he stays any further we’ll have to see.”
Dettori added: “I maybe sat too far back on him in Ireland and should have been closer to the pace, but today he has won like he should.”
Declaration Of War was second and could be out again in the Racing Post Trophy.
On a great day for Newmarket trainers, Benbaun (13-2) led home a British dominated Prix de l’Abbaye.
Mark Wallace’s pride and joy had not won anywhere but the Curragh for over three years but rider Pat Smullen got first run on Kingsgate Native to power home by two lengths.
Wallace said: “We were worried about the ground but we walked the track and it wasn’t too soft so we thought we’d take our chance.
“I’ve been training four and a half years, this is my first Group One, so it’s a dream come true.”
John Best’s Kingsgate Native, who broke the mould by winning the Nunthorpe Stakes as a juvenile, proved the effort was no fluke with his run.
Zarkava (6-1) marked herself down as a potentially special filly in the Prix Marcel Boussac, quickening right away from her rivals.
Owner the Aga Khan said: “She could come back at a mile next year and we will then see if she gets further. It is too early to talk about targets for next year.”
Yeats was undone in a tactical Prix du Cadran, finishing third to Le Miracle (7-1), who occupied the same position behind him in the Ascot Gold Cup.
Aidan O’Brien, the trainer of Yeats, reported: “It was a slow-run race. That’s it for the season – let’s enjoy him next year.”
Jean de Rouaille’s Satwa Queen (3-1), runner-up to Mandesha in the Prix de l’Opera 12 months ago, gained her just reward in a thriller for the 2007 renewal, coming desperately late under Thierry Thulliez.
Oaks winner Light Shift was prominent to the turn but dropped away.
