Marengo in line for Donny battle
Battle Of Marengo leads Aidan O'Brien's assault on the Racing Post Trophy at Doncaster on October 27.
The Ballydoyle handler has a huge team left in - but not ante-post Derby favourite Mars.
A powerful Irish challenge is supplemented by the Andy Oliver-trained First Cornerstone and Jim Bolger's Trading Leather.
Thirty-five horses remain in contention, and Richard Hannon's Olympic Glory could bid for more Group One honours. The Choisir colt won the Prix Jean-Luc Lagardere at Longchamp on Sunday and his only defeat came at the hands of Bolger's Dawn Approach in the Coventry Stakes at Royal Ascot.
Hannon could also run Havana Gold and Montiridge, while Ashdan, Dundonnell, Steeler and the highly-regarded Telescope are others to note.
