Christophe Clement is reluctant to run Arlington Million winner Gio Ponti in the Prix de l'Arc de Triomphe.
The Longchamp autumn highlight had been considered as a mouthwatering target for the four-year-old, who was winning his fourth consecutive Grade One on Saturday.
But Clement, a former assistant to Luca Cumani, is now cool on the idea of sending his headline act to France.
"We must sit down to think about plans, but I am not sure about the Arc," revealed the American-based handler.
"I must speak to my owners, but why would you compromise his career by shipping him all the way to France?
"The Arc would not be in my thoughts."
Clement instead plans to run Gio Ponti at the Breeders' Cup meeting in November.
Although the colt is in the frame for a clutch of races at Santa Anita, the Chantilly-born trainer could go for the jackpot in the Breeders' Cup Classic.
Clement added: "He is very versatile horse - he can go on any sort of ground - but I believe he is best over a mile and a quarter.
"We will keep our options open, but there is the Breeders' Cup Classic to think about.
"He's a wonderful, wonderful horse and we are so lucky to have him in our barn.
"He was a very good three-year-old but we've been patient with him and have now been rewarded.
"It is not easy winning four Grade Ones but he has done that now and we are very proud."
