Although previously ruled out of the Prix de l’Arc de Triomphe, Prix Niel winner Fantastic Moon may be supplemented for Sunday’s race.

The German Derby winner, trained by Sarah Steinberg, has demonstrated a preference for a sounder surface and may receive his preferred ground conditions for the 'Arc' with an overall dry forecast for the week ahead.

Fantastic Moon was a comfortable winner of the traditional three-year-old trial race for the 'Arc', the Group 2 Prix Niel, which was run on good ground. He defeated a competitive field in ready fashion, beating Group 1 Grand Prix de Paris hero Feed The Flame by two-and-a-half lengths, with French 2000 Guineas winner Marhaba Ya Sanafi back in fourth.

"We discussed it yesterday, because the weather forecast is dry and the sun in shining in Paris, perhaps we will get good ground," said Liberty Racing's Lars-Wilhelm Baumgarten.

"We will decide as late as possible because every day is important for us. How the horse is, how is he looking and working.

"We have a few opportunities too with the Breeders' Cup and the Japan Cup and now we have the option of the Prix de l'Arc de Triomphe again.

"We will see – our vet will check him, he will gallop in Munich and then we will see what's going on and what the weather forecast will be in Paris.

"We decided two weeks ago that we would not run but the situation is new, the ground is better than we expected and the horse is better than we expected 14 days after the Prix Niel.

"It's new information and a lot of horses are out of the race, so we will see."
