Henry de Bromhead expects Petit Mouchoir to "improve plenty" after his recent comeback, in which he finished second to Footpad at Leopardstown.
But the County Waterford-based handler admits only time will tell if that will be enough to turn the tables on his Willie Mullins-trained rival in the Racing Post Arkle Trophy at Cheltenham next month.
De Bromhead said: "I think he'll come on a lot for the run. He obviously had the setback after his first run this season, we got him to Leopardstown but I think that he'll improve plenty for it.
"Whether he'll improve enough to beat Footpad, who was hugely impressive on the day and has been all season, I don't know. But I think we should definitely come on for the run."
