Willie Collum was the man in the middle for Celtic vs Rangers today.

The experienced official faced the unenviable task of making most of the big calls on derby day in Glasgow.

He was supported by David McGeachie and Ross Macleod as his assistants, meanwhile, Steven McLean was on VAR duty with Graeme Stewart.

Here’s how we saw the major decisions made in the game…

John Lundstram red card

Just when we all thought the first half was going to pass without incident, the Rangers midfielder lunged in on Alistair Johnston at pace.

With his studs showing, he didn’t connect with any of the ball, and indeed, caught the Celtic defender’s calf, high above the ankle.

An initial booking was given, but after a VAR check, Collum was advised to check the pitchside monitor. Unsurprisingly, he changed his mind and brandished a red. It was a dangerous challenge.

As clear a sending-off as you’re likely to see, but credit to the officials for reviewing the footage and arriving at that conclusion.

Verdict: Correct decision

Celtic penalty

Mohamed Diomande appeared to catch Matt O’Riley as he looked to open up his body inside the box.

The Celtic goalscorer fell dramatically, and the initial decision was to point to the spot.

On the face of things, this looked to be the right call, however, a lengthy VAR check was carried out with the view from Steven McLean that it was actually O’Riley who kicked into Diomande. It’s hard to argue this wasn’t the case.

Collum checked the incident on the monitor again and he stuck by his on-field decision. However, we feel he did get this one wrong, although it is important to recognise that it is debatable.

Verdict: Incorrect decision

Offside goals

Not really too much to add to these calls.

The attacking phase of play was carried out before the flag went up from the linesman, which then saw the goals chopped off. Collum and his officials enjoyed a great game on the whole, keeping control of the big occasion.

Verdict: Correct decisions
