Kenny Miller is convinced Rangers should have been awarded a penalty for a pull from Celtic hero Cameron Carter-Vickers.
The defender netted the crucial goal at Ibrox to send Ange Postecoglou's men six points clear at the top of the Premiership table.
However, it's another flashpoint involving the American international that caught the eye of Miller.
As James Tavernier whips the ball in from a corner, Connor Goldson is pulled by his shift by Carter-Vickers.
Miller told Sportscene the incident was worth of Willie Collum pointing to the spot, and insists VAR would have given the decision to Rangers.
He said: "This for me, if VAR is in, is a stonewall penalty, or if Willie Collum sees that.
"He's got a hold of him, a whole chunk of the jersey. Connor Goldson is trying to react and adjust to the flight of the ball, and his movement is impeded.
"If that is seen it's a penalty, but you will see that at every corner and every free-kick that is given. There is a bit of jostling, but I think that gets given next year if VAR is in."
Miller was slightly more lenient when it came to a handball incident involved Carter-Vickers.
Ryan Jack's cross struck the centre-back on his upper arm in the penalty box and whistler Collum waved away the claims.
Former Rangers and Celtic star Miller said: "I'm not even going to pretend to know what the handball rule is, but I do think on another day, or another ref might give it.
"It would be very, very harsh because I do think Carter-Vickers arms are by his side, but in recent weeks we have seen those types of things given."
Michael Stewart insisted there was no chance it was a spot-kick during his analysis.
Stewart said: “It does come off his arm, there is no doubt, but it’s not a penalty kick. His arm is in a completely natural position, and thankfully the laws have been changed to reflect that."
