A former ref has brutally urged Willie Collum to "out of the limelight" after three hugely controversial calls in the match between Rangers and St Johnstone.

The whistler awarded Rangers a penalty for a handball, sent off Nicky Clark and then cautioned Ryan Jack for a possible sending off challenge.

And in the aftermath, ex-ref Des Roache has slammed Collum's performance at Ibrox, stating: "His (Collum's) best days are behind him."

Collum first pointed to the spot at Ibrox when James Brown was ruled to have handled in the area. The ball did appear to strike the full-back on the arm after a deflection off of Connor Goldson from close range.

Later in the first half, Clark was shown a straight red card for a tackle on Jack. After a delay, Collum brandished a red card to reduce St Johnstone to ten men before the break.

Further controversy ensued when minutes later Jack flew into a challenge on Adam Montgomery. Collum showed a yellow card before heading to the pitchside monitor to review the tackle.

After a second look, Collum decided to back his original decision and stick with a caution.

Roache insists all three decisions were incorrect and slated Collum as he insisted the official must be "held accountable".

He told Grosvenor Sport: "The penalty call was wrong in my view. James Brown couldn’t possibly get out of the way when the ball hit his arm.

"It was never a red card when Nicky Clark challenged Ryan Jack – and Jack should have been sent off for his challenge on Adam Montgomery. So there were three mistakes.

"Everyone can have a bad day at the office – a player or a referee – but when you continue to have bad days then what happens? Do the SFA continue to appoint him?

“I think it is time he’s held accountable, and that’s up to the SFA and the referee’s committee. They have to decide what games he gets now.

"If it was me, I would take myself out of the equation. His best days are behind him. As I say, if I was making as many highlighted errors, I would take myself out of the limelight."
