He takes a drop back in trip now with his first three runs having been over seven furlongs.
O’Brien introduced a nice sort in Old Glory on the same card last year and looks to have some fascinating newcomers this time. Battle Of Liege makes his racecourse bow in the Irish Stallion Farms EBF Maiden over seven furlongs.
The War Front colt is a full-brother to Breeders Cup Juvenile winner Hit It A Bomb and Cheveley Park winner Brave Anna.

Opening the action is the Welcome Naas Mens Shed Claiming Race and Denis Hogan will be hoping to strike with Be Like The Bird having acquired her in a claiming maiden at Tipperary.
The Dandy Man filly drops back in trip now but had run well over a similar distance when fourth at Sligo.
Connections try her in cheek-pieces now and she bids to confirm form with Vormir who was behind her in fifth last time.
