Marcialis said: “He’s a fantastic horse. When I started training in France, I only had two horses and he was one of them.
“He went close many times in the past, but now he has finally won a Group One.
“He was second over 10 furlongs last time, but today was his best performance.
“I changed the way we work him in the morning. I know him very well, I haven’t changed a lot, but he’s a champion horse.
“I think he’ll have a break now as he’s had three races in one month, then we’ll build him up for the Arc.”
Andre Fabre registered the 800th Group-race success of his long and illustrious career when Persian King returned to winning ways in the Prix du Muguet.
Winner of the French 2000 Guineas last season, he only ran once more when second to Sottsass in the French Derby.
Surprisingly beaten by stablemate Magny Cours on his return two weeks ago, he improved for that run and left the impression there was even more to come going up in trip.
Boudot was on board and told Sky Sports Racing: “He did very well today and it was nice to get another win on him.
“He was good at three and now he’s won at four.
“(Pretreville) came up on my outside, but my horse showed good stamina in the last furlong.
“There’s still more to come from him. He improved from his first run today.
“I don’t know about a mile and a half, it’s difficult to say, but maybe his next target will be the Prix d’Ispahan where one furlong more will be OK for him.”
