Nico de Boinville believes a loss of concentration was to blame for Might Bite's wayward performance in winning the RSA Chase at the Cheltenham Festival.The eight-year-old seemingly had therace won jumping the last, but he then veered across the track and almost pulled himself up to a walk before regaining his momentum when fellow Nicky Henderson inmate Whisper laid down a last-gasp challenge. De Boinville's mount eventually won by a nose, but the rider felt Might Bite's performance compared favourably with his 2015 Cheltenham Gold Cup victor Coneygree. The jockey told his 32Red blog:"Obviously, a lot of people have focused on what happened after the last but he actually tried to pull himself up going past the stands with a lap to go. "He gave himself a breather there, a good breather, and I had to ask him to go on again after the water jump. "He kicked on again in a manner very similar to Coneygree and he absolutely winged the second-last."I saw the same stride at the last but he lost concentration - he had one eye on the entrance - and put down on me."Some have suggested he emptied out on the run-in but to do what he did - to basically go from a standing start to galloping again in such a short space of time - is definitely not the sign of a tired horse."We have a horse of immense potential to look forward to now."
