Rangers' players should have gone 'berserk' to pressure VAR amid their strong shout for a penalty in extra-time in their Scottish League Cup final loss to Celtic.
That's the viewpoint of pundit Neil McCann.
Liam Scales blatantly pulled back Vaclav Cerny after the Rangers attacker nicked the ball off the defender and looked to cut inside towards Kasper Schmeichel's goal.
John Beaton - the on-field referee - awarded a free kick and booked the Irish centre-back for the foul, however, replays clearly showed that Cerny's foot was just inside the Celtic box, and therefore by the letter of the law, a penalty should've been given.
VAR did not intervene though, and James Tavernier's resultant free-kick sailed over the bar.
"We said it at the time," the former Gers and Hearts winger told BBC Sportscene. "If you are on the line you are inside the box.
"Watch Cerny's foot - Scales has taken a horrible touch from Scales and look at the jersey pull.
"Cerny's right foot is on the line. He (Scales) absolutely panics. The foot is on the line and he is tugging him down - that is what brings him down.
"His foot is on the line and he is in the box and therefore it should be a penalty.
"I'm amazed that the Rangers players are not going berserk there and putting pressure on VAR to take a look at that.
"Maybe they have and they have just said to John Beaton there is 'nothing to see here' - there is plenty to see here, that should've been a penalty."

Fellow pundit Scott Allan, formerly of the Hoops, added: "It's a huge talking point and for me it's a penalty. We have touched on the foot on the line and the pull.
"For me the big thing is, if I was a player on the side there - it's the reaction of the Rangers players.
"They didn't really put any pressure on the referee to look at it.
"Cerny himself wasn't making much noise about it but for me it's a stick-on penalty."
