Corine Barande-Barbe believes Cirrus Des Aigles will need the run when he makes return in Saturday's Qatar Prix Dollar at Longchamp.
While the main action from Paris is on Sunday, there are plenty of quality Pattern contests to be enjoyed a day earlier, with Barande-Barbe's stable star undoubtedly taking top billing.
The three-time Group One winner has not been seen since passing the post in second in Prix d'Ispahan in May, a race he was subsequently disqualified from after a prohibited substance was found in his sample.
Barande-Barbe has since appealed and the case is ongoing.
The six-year-old's main target is the defence of his crown in the Qipco Champion Stakes at Ascot on October 20, where he is set to come up against the world's highest-rated racehorse, Frankel.
"He is running on Saturday and he is well, but he will need the race to get him ready for Ascot," said Barande-Barbe.
"I am not worried about the ground as he goes on all different types of going. I think he will love the ground.
"I am happy with him at home. He will need the race but I still think he will run very well."
Cirrus Des Aigles will face eight rivals, including Godolphin's Hunter's Light, the John Gosden-trained Colombian and progressive four-year-old Maxios.
Gosden's Shantaram returns to the track in the Qatar Prix Chaudenay, run over a mile and seven furlongs.
The three-year-old has not been seen since winning Newmarket's Bahrain Trophy in July, missing the Great Voltigeur Stakes at York and subsequently the St Leger at Doncaster after suffering a setback.
Hugo Lascelles, racing manager for owner Lady Bamford, is hoping conditions in Paris are not too testing this weekend.
Lascelles said: "He's back in good form now so we'll give it a go and see what happens.
"They've had a bit of rain, which won't help, but we'll definitely let him run and see how he gets on.
"He stays in training next year."
Shantaram is joined by Andrew Balding's Mysterious Man and Pale Mimosa from the Irish yard of Dermot Weld in an 11-runner field.
There is also British interest in the Qatar Prix Daniel Wildenstein, with Balding's supplemented Highland Knight taking on seven opponents over a mile.
East Ilsley trainer Hughie Morrison saddles star fillies Shirocco Star and Coquet in the Qatar Prix De Royallieu.
Shirocco Star has been placed in the English and Irish Oaks as well as the Ribblesdale Stakes at Royal Ascot.
She is fitted with blinkers on her first start since finishing fourth in the Yorkshire Oaks.
Morrison said: "We're just putting the blinkers on to help her concentrate really. We don't think she's ungenuine, she just seems to think she's done enough once she's hit the front.
"I haven't had chance to properly analyse the race yet, but obviously it's a drop in class as it's not a Group One.
"She goes on any ground, so hopefully she'll run very well."
Of her stablemate, the trainer said: "The ground is probably against Coquet but at this stage of the season, there aren't many options left.
"If it wasn't October, we probably wouldn't be running and we'd wait for the better ground, but I don't think we're going to get that now so we'll let her take her chance."
