Jockey Aidan Coleman believes Katenko has the capability to make an impression in the Betfred Cheltenham Gold Cup.
On just his third outing since joining trainer Venetia Williams from France, Coleman helped the gelding to an impressive victory in a handicap chase at Sandown on 5 January.
He was entered in the abandoned Peter Marsh Chase at Haydock this weekend and Coleman believes he could appear at one of the forthcoming big Saturday cards instead.
"Hopefully I will be part of the Gold Cup, too," Coleman told his Racing UK blog.
"The owner of Katenko is keen to go that route and if he keeps improving the way he has so far in his three races in the UK, he could be a live outsider.
"I do genuinely think he could be a Grand National horse as he ticks all the boxes, so perhaps he might line up at Aintree next year, but there's a lot of water to pass under the bridge first.
"He was entered at Haydock, although was never going to run - even before it was called off - and I guess he might run at Cheltenham at the end of the month or Newbury in February - we'll have to see what Venetia has planned."
