Personally I have no issue with the contact on Griezmann being a foul - heel clip like that is easily enough to make you fall.
However there were angles not viewed by the VAR (???) that showed Risdon did touch the ball before making contact with Griezmann. Why were these angles unavailable to the VAR? Ref clearly thought Risdon got the ball live.

Then a couple hours later Argentina is denied a clear cut pen which the VAR doesn't look at at all?
Consistency was, is and continues to be the biggest problem with it.

On another note, does anyone know if the "clear and obvious error" was an A-league memo, or is it also being used that way for the world cup too? I mean officially - has it been stated that that's how they will be using it?
