Winter could be joined by stablemates Hydrangea and Rain Goddess.
So Mi Dar is in line to make her first appearance since October when she lost her 100 per cent record when third in the Prix de l'Opera at Chantilly.

Charlie Appleby is double-handed at this stage with Sobetsu and Falmouth Stakes runner-up Wuheida, who was taken out of the Prix Rothschild at Deauville on Sunday but is set to take her chance at Goodwood.
Appleby said: "Wuheida will go to the Nassau.
"I couldn't be any happier with how she came out of the Falmouth.
"She put in a nice bit of work in midweek and we will take a look at her again on Saturday."
Roger Varian has left in impressive Pretty Polly Stakes scorer Nezwaah, while Aim To Please, Blond Me and Queen's Trust complete the list.
