Dual Arc winner Treve is the headline attraction among the 13 names left in the Grand Prix de Saint-Cloud.
The five-year-old returned to action in the Prix Corrida at the Parisian track last month against her own sex, proving a cut above the opposition when she cruised to victory in the hands of Thierry Jarnet.
Trainer Criquette Head-Maarek may also run Altaira in the same Al Shaqab Racing colours as her stable star on Sunday.
“Touch wood, Treve is in tremendous form and Criquette is very pleased with her,” Harry Herbert, racing manager to Al Shaqab, said.
“There is a bit of rain around and we would like some of that. You saw in her last race she seems to be better than ever and hopefully she will put up a bold performance and take another step in the right direction before a shot at a third Arc.
“It is lovely to see her come out of a race so well. We go into Sunday full of hope.”
Andre Fabre, chasing an eighth victory in the race, can call on Manatee, Feodora and Hong Kong Vase winner Flintshire.
“He’s going for the Grand Prix de Saint-Cloud and he’s going to run a good race,” Fabre said of Flintshire.
“The ground will suit him probably and we’ll see. He’s always been a consistent horse.”
