Ruby Walsh has not ruled out Un De Sceaux making a return to trip to Britain on his next start to defend his crown in the Sodexo Clarence House Chase.
The Willie Mullins-trained eight-year-old got his career over fences back on track on after gaining a fifth Grade One success with victory in the Tingle Creek at Sandown.
Although the Closutton-handler earmarked the Paddy Power Cashcard Chase at Leopardstown later this month as the most likely target for Un De Sceaux, Walsh feels that a trip to Ascot to contest the Grade One prize on January 21 could be a more suitable option.
Walsh said on Racing UK: "I'm sure he is entered at Christmas. He had a plenty hard enough race for his first run of the season and whether he turns out that quick only time will tell.
"He won at Ascot last year and I'm sure going back there wouldn't be out of the question.
"We know he gets further so stepping up in trip won't be a problem but ground will be the deciding factor in that."
