Ex-Prem referee and now PGMOL representative Chris Foy has confirmed Brentford's equaliser at Arsenal stood because of a human error mistake on VAR.
Lee Mason appeared to forget to draw the lines as explained by Foy.
He said: "Ivan Toney puts the ball in the net and VAR Lee Mason obviously runs through the checks.
"VAR was looking to see if there was an offside and whether Ethan Pinnock had blocked off Gabriel in the build-up.
"He looked at the possible foul and decided there hadn't been one and therefore referee Peter Bankes hadn't made a clear and obvious error.
"However, in the build-up to the goal, Christian Norgaard whose cross it is that Toney heads in, is in an offside position"
"However, the truth is that VAR didn't fully investigate with the lines. The lines, simply, didn't go down. And that counts as human error.
"Had the lines gone down the goal would have been disallowed for offside."
