Gordon Elliott believes Don Cossack will have to raise his game if he is to claim victory in the Bar One Racing Drinmore Novice Chase at Fairyhouse tomorrow.
After three brilliant displays in the bumper sphere, the six-year-old was expected to take high rank in the novice hurdling division last term, but failed to make a significant impact.
The giant gelding was always likely to fair better over the larger obstacles, however, and after making a winning debut over fences at Galway, he pushed Morning Assembly all the way in a thrilling Grade Two prize at Punchestown a fortnight ago.
"He seems to have come out of his last run well. He just got touched off by a Grade One winner, so he hasn't done a lot wrong," said Elliott ahead of the Grade One Drinmore.
"I think he'll have to improve again to be winning on Sunday, so we'll see what happens. We're happy with him at home."
Gigginstown House Stud have a second runner in Road To Riches, who won his only start over fences at Naas.
His trainer Noel Meade said: "It looks a very good race and we just have to hope he's up to this level."
Sizing Rio has won his first two starts over fences, at Tipperary and Cork, and deserves the chance to test his powers at the highest level.
Trainer Henry de Bromhead said: "We're going up into a Grade One now, so we'll see where we stand. The ground is nice and we're happy to let him take his chance."
The six-runner field is completed by Art Of Logistics, Carlingford Lough and likely outsider Clar Na Mionn.
