'Ridiculous': VAR error costs Sydney FC goal in A-League decider

Sydney FC fans, look away now.

Coach Steve Corica was left fuming after VAR failed to come to his aid in Sunday's A-League grand final against Perth Glory.

The Sky Blues thought they had scored the opener in the 28th minute when Michael Zullo whipped the ball into the box and Glory defender Matthew Spiranovic accidentally knocked it into his own net.

But Sydney's cheers soon turned to despair when the players realised the linesman's flag had been raised for offside.

Referee Shaun Evans sent the decision to VAR, but the decision was upheld.

Zullo was the man deemed to be offside when Alex Brosque unleashed his pass.

Replays - aided by the yellow line - showed Zullo to be in line with Spiranovic when Brosque passed the ball.

Corica received a yellow card for his protests and people debated the decisision furiously on Twitter.

But technically VAR got it right - with the review system only able to overturn obvious errors.

This one was so line-ball that there was no scope for VAR to overturn it under the current guidelines.

Sydney fans weren’t the only ones outraged by the blunder, with several prominent voices in the Australian football community weighing in as well.

Scores were tied at 0-0 at the half, but it was Perth who had the run of the play for most of it.
