Rhododendron is one of three fillies Aidan O’Brien has left in at the latest entry stage of the Prix De Diane at Chantilly this Sunday.

The Ballydoyle handler has left the race as an option for his 1,000 Guineas and Oaks runner-up although she is still unquoted in the antepost betting for the race with bookmakers.

O’Brien could also run Irish 1,000 Guineas runner-up Roly Poly and Pocketfullofdreams.

Other notable fillies left in the French classic are John Gosden’s Shutter Speed, Godolphin’s Saint-Alary winner Sobetsu and Freddy Head’s Terrakova. In all, 24 fillies have been left in the race.

Freddy Head has high hopes for the exceptionally bred Terrakova in Sunday's Group 1 heat, which is also known as the French Oaks.

By champion sire Galileo and out of Head's great race mare Goldikova, so far Terrakova is living up to her pedigree, winning a maiden on her only start at two before overcoming trouble in running to win the Group 3 Prix Cleopatre on her return at Saint-Cloud.

Head has always had this race in mind for his unbeaten filly, but feels she will stay further later in the campaign.

"I think she is very good," said the trainer.

"She's got a good cruising speed but also she can quicken. I know the family well, they are not too precocious so I didn't want to over-face her last season.

"For the moment 10 furlongs is her trip, but she finished off her last race very strongly and I'm confident she'll stay a mile and a half. She didn't have the clearest of runs that day but she found another gear, she's smart.

"I've also left another filly in, Listen In, but I'm not sure she'll run. I just want to see who else is running first."

Shutter Speed, winner of the Musidora at York last month, and stablemate to Epsom Oaks winner Enable, is likely to go off favourite in the race.
