Nicky Henderson believes it would be dangerous to underestimate Jonbon in the Arkle Trophy at next month's Cheltenham Festival following his workmanlike success at Warwick on Saturday.

Best of the rest behind his brilliant stablemate Constitution Hill in the Supreme Novices' Hurdle last season, the JP McManus-owned seven-year-old pursued a career over fences this term and was hugely impressive in winning on his debut at Warwick and in landing the Henry VIII Novices' Chase at Sandown.
