Maybe and La Collina are again set to lock horns in Sunday's Moyglare Stud Stakes at the Curragh and spearhead 18 entries for the fillies' Group One contest.
Aidan O'Brien's Maybe is unbeaten in four starts including the Chesham Stakes, the Silver Flash - in which she beat La Collina by a neck - and the Debutante Stakes. Sunday's run will be her first in top company, however.
Kevin Prendergast's La Collina bounced back from her sole defeat to beat the colts in the Group One Phoenix Stakes last time.
O'Brien has six other entries with After, Ahimsa, Chieftess, Devotion, Homecoming Queen and Soon all possibles.
Mick Channon's Samitar, impressive when winning the Albany Stakes, is set to have her first run since that day in June and is the sole entry from England.
Jim Bolger's Teolane is looking to bounce back from a couple of disappointing runs, while John Oxx's Rubina has ground to make up on Maybe from the Debutante Stakes.
David Wachman's Fire Lily and Dermot Weld's Yellow Rosebud are others of note.
