New Delhi, March 11 (IANS) Defending the video referral introduced at this World Cup, International Hockey Federation (FIH) president Leandro Negre Thursday said it is the teams and the officials who need to know how to use the system judiciously.

The Spaniard said everyone on the field, including the coaching staff, used the the video-referral poorly.

'Everybody from the umpires, players and coaches have to learn about the video referral. I must say a lot of teams in this World Cup have used the referral system rather poorly. Teams have to be wise in choosing which referral can change the course of the match. Some teams called for the referral when it was absolutely not needed,' Negre said.

The FIH is likely to review the video referral system at its executive committee meeting here Monday.

The new video referral system has come under fire from top coaches like Australia's Ric Charlesworth and India's Jose Brasa.

Brasa was livid after the onfield umpires Ged Curran and Roel van Eert went for a video referral, disallowing his team's third goal against South Africa.
