Jonbon is the star attraction for the Sky Bet Supreme Trial Rossington Main Novices' Hurdle at Haydock on Saturday.
Snapped up for £570,000 by owner JP McManus after winning an Irish point-to-point, the full-brother to the legendary Douvan has been impeccable in three starts so far for Nicky Henderson.
The six-year-old made a successful debut in a Newbury bumper last spring and is two from two over hurdles, most recently running his rivals into the ground in a Grade 2 at Ascot.
Jonbon is second-favourite behind Seven Barrows stablemate Constitution Hill for the Supreme Novices' Hurdle at the Cheltenham Festival, with his odds sure to be trimmed with another victory this weekend.
His potential rivals on Merseyside include the Harry Fry-trained Might I, who was runner-up to Constitution Hill at Sandown in December, and the unbeaten Donny Boy from Nick Alexander.
Alexander said: "The Rossington Main is the plan. It's obviously a big step up in class and who knows what will happen, but we'll give it a go.
"We're very excited about him, we believe in him and hopefully he'll run well.
"It'll be fine if Jonbon scares everything else away!"
Donald McCain could send 27 length Sedgefield winner Richmond Lake, while Ballycoose is a potential raider from Northern Ireland for Stuart Crawford.
Meanwhile, jockey turned trainer Sam Thomas has entered No Risk At All, a progressive type, second to Jonbon at Newbury in November.
Nicky Richards' Nells Son hasn't finished outside the top two in seven career starts and could prove a lively outsider for the Cumbrian trainer.
