Henderson out to dethrone Kauto

Nicky Henderson feels it is his job to ’dethrone Kauto Star’ with Long Run in the William Hill King George VI Chase at Kempton on St Stephen's Day.

Long Run prevented Kauto Star from winning a fifth consecutive King George last season and when Paul Nicholls’ superstar trailed in third in both that race and the Gold Cup, and was then pulled up for the first time in his career at Punchestown, many feared the worst.
