Celtic vs Rangers VAR watch as John Lundstram red card takes centre stage on derby day
This game had just about everything.
Celtic moved another few points towards the Premiership title with a 2-1 victory over rivals Rangers at Parkhead in front of a packed house of 60,000 punters. Matt O'Riley opened the scoring with a drilled effort on 35 minutes before John Lundstram had the misfortune of lazily sticking a leg out towards a Daizen Maeda cross to nudge the ball into his own net to make it 2-0. But when Gers looked like capitulating, Cyriel Dessers came up big and headed a Dujon Sterling assist into the back of Joe Hart's net to keep his side in the game.
Still, Gers weren't about to make things any easier for themselves and Lundstram compounded his og misery by getting himself sent off for a challenge on Alistair Johnston.
Referee Willie Collum had a very busy afternoon as did Steven MacLean and his assistant on VAR.

Lundstram red
The midfielder had already been the villain of the piece among his own supporters for his own goal but he may now have played his last game for the club and ended it in disastrous fashion. With the ball midway into Celtic's half, and Alistair Johnston in relative comfort in possession, Lundstram came steaming in and scythed down the defender. On an initial viewing it was a yellow card brandished by Collum but he was called to the monitor.
On second and third viewing, Lundstram caught the Canadian on the ankle with his studs and the booking was upgraded to a red. It looked like a clear sending off, but not everyone agreed. Kenny Miller, on Sky Sports commentary duties, said: "He's going to win the ball. Johnston plants his leg and he catches him. Every tackle like that cannot be a red card. See in real time, that's never a red card. Now look at the still.
"You know what, the way the game is going now. That is not a red card, there's no way. The still showing the contact. Every kick can't be a red card.
"Alistair Johnston plants his foot in the way of where Lundstram is going. Incredible."
O'Riley penalty
O'Riley was excellent for his side with the opening goal and he also had a number of chances to add to his tally. And he won a spot-kick in the second-half. The Denmark international went down after Mohamed Diomande caught him inside the area but the Rangers midfielder claimed he had simply stood his ground and that his opponent ran into his leg.
Collum immediately pointed to the spot before a lengthy check was called for. Unusually, the ref stuck with his own on-field decision and awarded the pen.
Either way, it was eventually saved by Jack Butland to keep the score down.
Quick check
Dujon Sterling was accused by Alistair Johnston of handling the ball inside his own area and it was officially checked out by officials only to be waved away.
Maeda disallowed goal
The Japanese forward thought he'd made it 3-1 late on as Celtic looked to consolidate their lead as he took the ball on his chest from a decent ball forward and slotted it home beyond Butland.
As it was, though, he'd strayed offside and it was chalked off. Right call.
