The owners of Prix de l'Arc de Triomphe favourite Sea The Moon plan to keep the unbeaten three-year-old in training next season.
Niko Lafrentz, whose family bred and own the son of Sea The Stars, has turned down numerous offers for the 11-length German Derby winner.
He is due to have his prep race for Longchamp in the Grosser Preis von Baden this weekend and speaking to www.GermanRacingReview.com, Lafrentz said the Markus Klug-trained colt would not be sold at any price.
"It's hard to find time to watch the Derby again because my phone will not stop ringing! People will not accept that Sea The Moon is a member of our family and is not for sale," he said.
"No amount of money will make us sell him. We keep rejecting bids and any additional amount of money offered will not make any difference; he is our horse.
"He will have three or four races next season. We would love to bring him to England. It would be a dream to have him run at Royal Ascot."
Sea The Moon is one of 11 declared for Sunday's Group One, with Lucky Lion an eyecatching contender following his recent victory over Noble Mission in a Munich Group One, although he was left toiling by Sea The Moon in the German Derby.
He is one of two runners for Andreas Lowe with Sirius, who recently triumphed at the highest level at Hoppegarten, also in the line-up.
The Klug-trained mare Berlin Berlin was second that day and reopposes along with third-placed Lucky Speed.
Terrubi beat Brown Panther in a Group Two at Longchamp on his most recent outing and he tries his luck again.
