David Wachman is looking forward to Legatissimo having a stiffer stamina test when she bids to add the Investec Oaks to her Qipco 1000 Guineas success at Epsom on June 5.
The daughter of Danehill Dancer aims to become the first filly since Kazzia in 2002 to complete the 1000 Guineas-Oaks double and Wachman believes it was her staying qualities that helped her win the day at Newmarket.
Speaking at the Breakfast With The Stars morning at the Surrey course, the County Tipperary-based handler said: "She seems very well and we are happy with her as she has done nothing wrong. She has only done two or three bits of work and we are very happy with her."
He added: "A mile is a short as she would ever go as a true-run mile sees her stamina come into it.
"We have always liked her a lot. Last year she was quite big and tall and we hoped she would maybe turn into a nice filly.
"She has definitely got stronger since her win at Newmarket."
Legatissimo is ante-post favourite and her main market rival is Crystal Zvezda, who has attracted plenty of support since running out an impressive winner of a Listed contest at Newbury.
Trainer Sir Michael Stoute hopes to have a jockey booked for her as Ryan Moore, who won on her at Newbury, will be aboard Legatissimo at Epsom.
"We had a look at Crystal Zvezda after Newbury and we are happy with her so she will go for the Oaks," said the Newmarket trainer.
"She has taken a long time to come to hand this spring, but a week before the race at Newbury she showed a real sparkle.
"We have always liked her and she is a wonderful specimen. We are now going to work on getting her a rider and hopefully have that organised in the next day or two."
John Gosden was pleased with his two Oaks hopefuls, Musidora scorer Star Of Seville and Jazzi Top, winner of Newmarket's Pretty Polly Stakes, after they worked on the track.
"Star Of Seville I think did idle in the Musidora," said the Newmarket trainer.
"Although there is nothing in her pedigree that says she will stay a mile and a half, she is a big, strapping filly and we were very happy with her today.
"She does not have to lead, she can sit second, third or fourth, just as long as there is a good gallop she will be fine - she just doesn't want it to turn into a sprint.
"Jazzi Top is the same on pedigree and that last furlong here they go up hill, but she is a real streetfighter. Both fillies looked good together this morning and they are two lovely fillies to bring here."
French trainer Andre Fabre was delighted with Al Naamah after the filly was put through her paces over the Epsom undulations.
"She is a fantastic looking filly with a great pedigree and is exactly what we expected her to be," he said.
"She is still big and backwards, but I think she is ready for the Oaks.
"Bringing the horses over here for this is a great addition to their training as these horses don't see the bend downhill at home and it also makes a big difference for the jockey as well."
Though Found is the shortest priced of Aidan O'Brien's Oaks entries, she could be switched to the Investec Derby as the Ballydoyle team have at least two leading contenders for the fillies' Classic in Cheshire Oaks winner Diamondsandrubies and Together Forever, who was just touched off by Star Of Seville in the Musidora.
"Diamondsandrubies is a tough filly who really showed her tenacity in the Cheshire Oaks," said Coolmore's UK representative Kevin Buckley.
"When she came the round the bend she got a real slap in the face, but she kicked on and gave even more.
"Together Forever was stepping up from (winning) the Fillies' Mile (at Newmarket in October) and we wanted to establish that she would stay the trip and there was not a question about her stamina.
"Nothing fazes her and she has a lot of quality."
