Philippe Clement has demanded answers from the SFA over the failure of VAR to pick up a 'clear' penalty for Rangers in their 2-1 defeat to rivals Celtic.
Canadian full-back Alistair Johnston handled in the penalty area when tussling for the ball with Ibrox winger Abdallah Sima but Nick Walsh didn't see the incident with both players in front of him.
VAR Willie Collum halted play to look at the moment again but quickly suggested there was no issue with the initial call to play on.
This prompted widespread shock with all three Sky Sports panellists covering the game, Kris Boyd, James McFadden and Neil Lennon, saying there was a clear penalty kick missed.
Then in the second half, Sky informed viewers that an offside in the build-up to the incident was the reason it was not given as a penalty.
And the Belgian manager is adamant this was the VAR covering their tracks after an error.
He told the BBC: "I'm also really curious why this handball wasn't given because it's a really decisive moment in the game to come back to 1-1. I'm really curious about that. It's a clear handball so it's a penalty and I think everybody who sees that clear handball will say it's a penalty."
The BBC reporter suggests that VAR pictures showed an offside prior to the flashpoint.
Clement responded: "Yes, but after the game. In the second half. We never got this information in the first half so that was not in account at that moment. So it's strange we didn't get this information that there was an offside and that there was no clear signal that it was offside. It's not an offside situation given with the ball there in the position which he was offside. So it's an explanation afterwards to cover a decision that was wrong."
