The Derby-winning handler is also planning to send Goodwood Group 2 winner Finjaan to Longchamp to take on Freddie Head's six-time Group 1 winner Goldikova in the Prix de la Foret on 3 October, while stablemate Askar Tau will be out to supplement his Doncaster Cup success with another in the Prix Du Cadran the following day.
"Askar Tau is in brilliant form," insisted Tregoning. "If you go there with a fresh horse at the end of the season, you usually have 10lb in hand and Askar Tau hasn't had too many races this season."
