Fuming Rangers boss Gio van Bronckhorst felt VAR could have changed the game for his side as they saw two penalty appeals waved away in the Dundee United draw.
The visitors were screaming for a penalty in the first half at Tannadice when the ball struck Ross Graham's arm but referee Bobby Madden waved away their protests.
After the break Fashion Sakala appeared to be pulled back as he went to make contact from close range but once again the Rangers protests fell on deaf ears.
A Joe Aribo equaliser saved a point but title rivals Celtic can now pull clear and the Gers boss was asked about the incidents after the final whistle.
Van Bronckhorst told Sky Sports: "You know my standpoint: VAR will make it easier for these decisions which can be turning points.
"They can change games, but there's no VAR so end of discussion.
"What can we do? There's no VAR so every decision that the referee will make cannot be overturned.
"So we have to respect the decision he made.
"We see last Thursday where VAR decisions can change the game for us, today maybe as well.
"We can talk for hours here but the discussion ends because there's no VAR."
Rangers peppered Benji Siegrist's goal with shots in the second half but couldn't find a way to win, and Van Bronckhorst lamented their missed chances.
He continued: "With the chances we created - I think we had, I don't know, 29 chances today? - it was well enough to win against Dundee United here in their own ground.
"But we didn't, and that's why we lost points."
