Just half way through the second round of the new A-League season the video ref has been the main talking point from at least three matches.

In the Sydney Derby at the SCG, the Sky Blues were two up when Roly Bonevacia clawed one back in the 58th minute only to have the goal scrubbed off.

It sparked an angry reaction from RBB fans in the 30,500 strong crowd and ended in a straight red to Wanderers coach Markus Babbel after he exploded on the sideline.

Post-match Beath stood by the decision. None of the match officials clocked the offence at the time which was picked up by the VAR but replays appeared to show a clash between Wanderers Jaushua Sotirio and Sydney FC left back Michael Zullo in the lead up.

Beath told Fox Sports: "So let’s make it very clear that the offence that we’ve given for is actually offside.

"The attacker is clearly in an offside position and his action impacts on the defender, on Zullo’s ability to play the ball."

The referee said he was comfortable with the decision: "From a technical point of view the offside is the correct decision."

But the decision caused a meltdown on social media and led to impassioned pleas from retired Socceroos Archie Thompson and Mark Bosnich to immediately halt or bin the use of the technology.
