Aidan O'Brien: my team for the Prix de Diane

"Since she won the French Guineas, everything has went well. I've been very happy with her. The plan was always, if everything went well in the Guineas, to come back here. Everything has been very good since her last victory. I think she’s even better on better ground.

"Obviously, she won nicely the last time and it's her second run of the year. We were delighted. So if she did that again, obviously, we'd be over the moon. But everything has went well and we've been very happy with her since. And we always thought a mile and a quarter shouldn't be a problem to her.

"We're going to learn more on Sunday. And you're never sure what to do, but we always thought this distance wouldn't be any problem. She's good, very straightforward. She's well balanced. She's a medium-sized filly and usually travels well in her races.

"She's very like her sire St. Mark's Basilica. When he went up to a mile and a quarter, he improved again and everything she does is very like him, really. 

"The Diane is a very prestigious race, very important for a filly... it's a tough race to win.

"So you need a very good filly to do it, really, we always think.

“It's possible [she will stay 12 furlongs at some point]. You obviously couldn't be sure until you do it, but it definitely is possible, especially being by St. Mark's and on her dam side as well.”

“She ran in the Musidora the last time, the Oaks trial at York. It went a little bit steady for her, but she ran okay. So she was a possible for the Oaks.

"She had a couple of choices: the Epsom Oaks, Ascot for the Ribblesdale and Chantilly. So we're thinking at the moment she might go to the Diane. We think there's more improvement to come from her, and we think she'd like the trip, and we think she'd like the track as well.

"I think she'd like light and nice ground. I don't think she'd be mad about soft ground. She's a very good mover."

"We go through every furlong, as much as we do. We go on the grass on the track and try to prepare as well as we can for all different kinds of scenarios, and we speak and talk and communicate a lot as we go along, and we see where the best ground is.

"I think it's everything, really. It's talk and walk and just prepare as well as we can."

“I don't think so, it's always straightforward and I think it suits everybody when there's an even pace. I don't think it's ever about tactics. All we ever want is an evenly run race and then everybody finds out where they stand afterwards and whether their horse gets the trip or doesn't get the trip.

"And when the pace is like that, people and horses aren't on top of each other. That's the only reason ever. And I think everybody kind of knows where they stand when there's an evenly run race.”
