Corine Barande-Barbe believes Cirrus Des Aigles is "better than ever" after her pride and joy justified her confidence with a runaway victory in Saturday's Prix Dollar at Longchamp.
Winner of the Champion Stakes at Ascot in 2011 and second behind Frankel in the same race 12 months ago, the 10-furlong Group One has been top of Cirrus Des Aigles' agenda ever since the start of the season.
Many believed age had caught up with the seven-year-old when he was beaten on his first four starts of the campaign, but Barande-Barbe retained the faith and, as she predicted, the gelding looked more like his old self when scoring comfortably last weekend.
He looks set to return to Ascot on 19 October as a hot favourite and his trainer believes there is even more improvement to come.
Barande-Barbe said: "I'm very happy with him, he seems to have come out of the race in cracking form.
"I thought he was going to his top (form) from what I saw at home, I told everyone this before the race on Saturday and he confirmed it in the race.
"I think, at the moment, he is better than ever. I think he is still getting better and will be at his top level at Ascot, so we will see what happens.
"There is rain forecast. I don't think it is going to be very heavy, but hopefully the ground will be on the soft side and that will be fine for him."
On his last 14 starts, Cirrus Des Aigles has been ridden seven times by Christophe Soumillon and seven times by Olivier Peslier.
Soumillon was on board when he won the Champion Stakes and has also partnered him to his last two wins and Barande-Barbe hopes he will be available again on Champions Day.
"We are not sure yet. I think Christophe would like to ride him, but he has to see what other horses he has to ride," she said.
"When we know, we will confirm it and let everybody else know."
