“Magna Grecia, Hermosa and Magical are all well and on target for the Curragh next weekend,” said O’Brien.
“Everything has gone to plan so far.
“We mapped out the three runs for Magical, with the Tattersalls Gold Cup as her first main target this season.
“It’s possible we will have a few more runners in both Guineas. The ones that will be left in are possibles.”
O’Brien had a change of heart with Newmarket Classic winner Hermosa.
“We were thinking originally of going for the Oaks with Hermosa – but it’s less than a week between the Irish Guineas and the Oaks,” he said.
“We decided we’d go to the Irish Guineas, and from there on to the French Oaks.
“The French Oaks is worth nearly twice what the English Oaks is worth, and we thought it would be a nice stepping stone to go from a mile up to a mile and a quarter.
“Fairyland will be left in and is a possible, but could go back in distance.”
