She did not make her debut for Aidan O’Brien until last month, but ran a perfectly respectable race to chase home leading three-year-old filly Tarfasha in the Blandford Stakes.

O’Brien junior is expecting his big-race mount to improve for that outing fitness-wise, but admits she has plenty on her plate this weekend as she aims to overcome an extremely wide draw in stall 18.

Speaking from Dundalk on Friday evening, Ireland’s champion jockey said: “She had a very good run in the Blandford and it was a nice starting point after a long layoff.

“I think she was off for more than a year and the trip should improve her. The draw is far from ideal, though, and it’s hard to win from that draw.”

Chicquita is just one of three runners in Europe’s premier middle-distance contest for team Ballydoyle.

Yorkshire Oaks winner Tapestry has been supplemented at a cost of 120,000 euro and will be ridden by Ryan Moore, while last year’s Derby winner Ruler Of The World, the mount of Frankie Dettori, most recently claimed the Prix Foy over the Arc course and distance.

“You have to draw a line through Tapestry’s Matron run given the trip and the change of tactics,” said O’Brien jnr.

“She’s back up in trip and has a good draw (stall eight). She has to be ridden patiently. Three-year-old fillies have a great record in the race and she is well entitled to take her chance.

“He (Rule Of The World) won his trial nicely. He has worked nicely since then without obviously doing too much. He’s got a good draw (stall six).”

Moore feels Tapestry has place claims in a wide-open renewal, but has identified Japanese mare Harp Star as the horse he would most like to be riding.

“The first thing to say about this year’s Arc is it is one of the most open that I can remember,” Moore told Betfair.

“I genuinely went through the field and came up with a shortlist of 10, maybe more, and even then it wouldn’t be the greatest shock in the world if the winner wasn’t among them.

“Having ridden there a fair bit, I know the Japanese horses pretty well and I think the most talented horse in the race is undoubtedly Just A Way.

“But if I could pick any of the field to ride, it would probably be Harp Star. If you fancy Taghrooda, then I think that you have to fancy Tapestry at the prices. Taghrooda may have had an excuse that she was in season at York but, whichever way you cut it, my filly ran a great race there. The third horse, Tasaday, was seven lengths away in third and she ran a good second to Hillstar at Newbury subsequently.

“The step back to a mile didn’t work out in the Matron Stakes last time, but we know that a mile and a half on fast ground are her conditions and I am happy being drawn eight.

“I give her an each-way chance but this race will take some winning.”
