Indian coach Jose Brasa has said he feels that the video referral system which has been introduced for the first time in Hockey World Cup, need some fine-tuning with regard to its timing. He said the play should not be stopped for referrals when one team is in an advantageous position. Mr Brasa said India suffered against the mighty Australians on Tuesday because of the timing of the referrals by their rivals. Australian coach Ric Charlesworth also said the video referral system had made wrong decisions against his side in their 2-3 loss to England on Sunday. England captain Barry Middleton felt the referral system was affecting the flow of the game as the video umpire takes lot of time to come to a decision. South African captain Austin Smith had a similar view and hoped it will get better.
