Gordon Elliott believes that Don Cossack can develop into a top-class performer after his extraordinary victory at Navan on Sunday.
Having oozed class when winning at Naas in October, he was sent off at odds-on to confirm that impression but appeared to have a mountain to climb turning into the straight.
The free-wheeling Rory O'Moore was nearly half a furlong in front at one stage but Nina Carberry took the bold decision to set off in pursuit and prevailed by a length and a half at the finish.
"He's a good horse. He's only four but he's 17 hands so he's going to be a smasher down the road," said Elliott.
"We won't do too much this year, we're going to look after him.
Be All And End All
"The leader must have been half a furlong in front and the boys had gone to sleep a bit. If Nina got beat it might not have been her finest hour, but it worked out great.
"The other horse is no slouch and is two years older, he's a fair horse in his own right.
"We all want winners at Cheltenham but I don't think that bumper is the be-all-and-end-all for him. A couple of years down the road he could be anything so we're going to mind him.
"The Rockview Bumper at the Curragh (in May) could be his next run, it's very valuable, and then he'll go novice hurdling next season - he won't jump a hurdle in public this year.
"He's schooled well at home and jumps very well but we'll keep him as a novice for next year," he told At The Races.
