Rosdhu Queen tops 16 entries for Saturday's Dubai Duty Free Stakes, better known as the Fed Darling Stake, at Newbury.
William Haggas' charge ended last year unbeaten in four starts, culminating in victory in the Cheveley Park Stakes at Newmarket.
Richard Hannon has three in the running at this stage, although Sky Lantern is set to contest the Nell Gwyn Stakes at Newmarket on Wednesday instead.
She was initially due to run at Newbury but the likelihood of soft ground has seen the Hannon team switch their runners over.
"Maureen is proven on soft ground and the going can't really be anything but soft at Newbury at the weekend," said assistant trainer Richard Hannon jnr.
"We know she handles soft ground and has won at the track before so this seemed an obvious choice."
Hannon has also entered last Saturday's Kempton winner Zurigha and City Image.
The Gold Cheongsam was last seen finishing fifth at the Breeders' Cup meeting and she represents Jeremy Noseda while Ralph Beckett's Waterway Run finished one place behind that day and could reoppose.
Agent Allison, Annie's Fortune, Califante, Desert Image, Melbourne Memories, Tipping Over, Mystical Sapphire, Valais Girl and Ghanian are the other possibles.
