Top cricket umpire Richard Kettleborough is urging football to press ahead with video reviews - and to encourage ex players into refereeing.
Kettleborough, the world's leading Test official, is a fan of DRS in cricket and a keen observer of the changes on the way in football.
Before taking up becoming an official, Richard was a first-class cricketer who appeared in 33 first-class matches for Yorkshire and Middlesex. He was appointed to the ECB list of first-class umpires in 2006, before steppingup further to the full International Panel of ICC Umpires in 2009. Since then he has won the David Shepherd Trophy for ICC Umpire of the year in 2013, 2014 and 2015.
