Willie Mullins has sounded a few warning notes on RSA Chase contender Boston Bob.
The Graham Wylie-owned eight-year-old is unbeaten in two starts over fences - but has just those appearances under his belt since finishing second in the Albert Bartlett Novices' Hurdle at last year's Festival.
His most recent run came in the Dr P.J Moriarty Chase at Leopardstown, where he finished best of all to snatch the spoils by a nose from Texas Jack.
Mullins told the Daily Mail: "Like Hurricane Fly last season, Boston Bob has never pleased me all year.
"He's improving all the time and doing all right but I just hope I've done enough with him early on in the season to take on the sort of horse he'll meet in the RSA."
