Aidan O'Brien will unveil more Classic hopefuls at Leopardstown on Sunday.

O'Brien has as many as 10 in the colts' trial with Century City, Della Francesca, Landseer, Maderno, Roar Of The Tiger, Sahara Desert, Salentino, Stonemason, Temple Of Artemis and Ursa Minor among the 16 preliminary entries.
Sophisticat, who was a seven-length second to Sagitta 1000 Guineas favourite Queens Logic in last year's Cheveley Park Stakes, heads O'Brien's list of five runners in the fillies' equivalent.
She is entered along with 1000 Guineas possibles Alstemeria and Pietra Dura and Rockfel Stakes second Lahinch.
Vodafone Oaks hope Maryinsky, who finished a two and a half length second to Luca Cumani's Gossamer in the Meon Stud Fillies' Mile at Ascot in September, may also take her place in the line-up.
O'Brien also has Racing Post Trophy winner High Chaparral and Sorcerous among seven possible runners in the Listed Ballysax Stakes over one mile and two furlongs on the same card.
