Plans are fluid for Jealous Again, one of the latest high-profile recruits for the Godolphin team.
Formerly trained by American Wesley Ward, the juvenile filly posted one of the most impressive performances at Royal Ascot when bolting up by five lengths in the Queen Mary, and was subsequently bought by Sheikh Mohammed.
"The filly is not in our stable at the moment and we are not sure when she is likely to arrive. She will be really interesting, but I can't tell you where you are likely to see her because I don't know," racing manager Simon Crisford told At The Races.
The Ascot form was boosted by the impressive success of Queen Mary runner-up Misheer in Wednesday's Cherry Hinton and Crisford added: "We were delighted with the result."
Crisford also had news of Rio De La Plata, last seen finishing third behind Tamayuz 12 months ago in the Prix Jean Prat.
"Rio De La Plata had a setback in the spring, which meant he had to have time out of training, but he's back in full training now," he said.
"He had a respiratory problem and could be back in the second half of the season. Obviously we've got to get him fit enough to go for a race.
"I wouldn't have thought he'd run in the International at York first time out, but hopefully we can go forward and have a really good campaign with him."
