Nigel Twiston-Davies said: "He's a proper racehorse. The sort of horse we dream about.
"We've everything covered, but, at the moment, I think we are (heading for the) Champion Hurdle.
"It's worth another go, I'd have thought."
Twiston-Davies snr continued: "I don't think he stays (three miles). He was outstayed at Kempton by Yanworth, but he won't run again before Cheltenham so we've got a lot of time to think."
Sam Twiston-Davies would rather The New One stepped up in trip for the Stayers' Hurdle at the Cheltenham Festival.
He said: "Every time he comes here he wins ugly, but always comes out on top, which is great - his record here is exceptional.
"He's one of those horses that deals with conditions on the day and does what he has to do.
"As a jockey you want winners, so I'd love to have a go at the Stayers' Hurdle. I think he'd be running round in second gear and if he had anything left at the last he'd go close. He does have a lot of class."
Nicky Henderson said of the vanquished L'Ami Serge: "We haven't learned a lot, other than he's probably not a Champion Hurdle horse. He might go back over fences."
