Former England coach Duncan Fletcher has backed the much-criticised Umpire referral system in Test cricket, saying the innovation will improve decision-making, if used judiciously.
The system is in spotlight after three LBW appeals were referred on day three of the fourth Test between England and the West Indies in Bridgetown on Saturday.
"This is the exact same system I came up with 12 or 13 years ago when I was coach of Western Province. This system will not currently give you 100 per cent correct decisions, but it is there to help umpires.
"If the people administering the system during the match are not up to it, don't blame the system," Fletcher, who is currently coaching in South Africa, told BBC Sports.
The 60-year-old coach feels the innovation has reduced umpiring errors in the Test cricket.
"All we have to ask though is 'are there more correct decisions than incorrect being made?' The answer is yes, so the system is an improvement.
"Adding hot-spot technology and Hawk-Eye will also be good," Fletcher stated.
