VAR should be used like in tennis, says Australia coach Bert Van Marwijk

The Australian boss gave this thoughts after a controversial VAR decision marred the A-League grand final

Socceroos coach Bert Van Marwijk believes the Video Assistant Referee system should be implemented like its tennis challenge countepart, in the wake of the controversial decision in the A-League grand final.

Kosta Barbarouses' ninth minute winner for Melbourne Victory was assisted by an offside James Donachie, with the FFA admitting the decision couldn't be reviewed by VAR because of a server error.

Van Marwijk says a system that relies on players selecting a certain amount of incidents to review, such as in tennis grand slams, will function better than VAR's choosing what they see themselves.

"I saw the goal but I didn’t really see it that well from my position. Later on I heard that it was offside," Van Marwijk said at a press conference to name the preliminary 32-man Socceroos squad for June's World Cup in .

"In tennis the players can decide when they use the video referee. Maybe we can think about giving both teams one or two or maybe three possibilities to ask the video referee.

"Maybe that’s better and more honest because now everybody is depending on what the video referee thinks and sees [when it comes to flagging decisions]."

With VAR decisions interrupting games for up to four minutes, Van Marwijk was adamant the processing time of decisions has to improve, while also pointing out crowds were often in the dark during the process.

"I understand that you try to change the rules to make football better. A camera on the goal - I understand that. A video referee - I understand that," he said.

"But I already have seen games with video referees where nobody has seen the incident in which the VAR is flagging.

"The on-field referee had already made the decision earlier but is forced to take minutes over on the sidelines reviewing the incident, while everyone in the stadium doesn’t know what is happening.

"[The process] has to be quicker and faster to make decisions."

The controversial VAR system will be used at the World Cup despite its results in Australia being mixed over a two year trial.
