Hibs manager Lee Johnson has been talking to Sportsound ahead of kick-off at Easter Road, where there is currently a problem with VAR.

"There's a bit of a technical issue in terms of reporting the pictures back to [the referee]," Johnson said.

"It's working here, it's working there, but that connection between the VAR centre and Easter Road isn't working at the moment. If that changes VAR will be on, if it doesn't then we'll continue without it.

"The law of averages says we'll get that bit of luck at some point, and hopefully it's today. We want to win this game properly, playing our way, nice and aggressive, on the front foot.

"We can play a five comfortably, and Ryan [Porteous] can step in, drop in, or roll out given his technical quality."

Well, that was entertaining.

Matty Kennedy's brilliant goal put Aberdeen in front, and they were in control despite not creating much more.

Then, a horrible touch from Anthony Stewart allowed Jonah Ayunga to nip in and tackle him, and then the Aberdeen captain pulled him to the deck.

Stewart was dismissed and Saints got a penalty after a VAR check. Mark O'Hara's penalty hit the post and came back off Kelle Roos and trickled into the net.

All square.

Reo Hatate got the festive fun underway at Celtic Park with a deflected strike from the edge of the box.

Kyogo Furuhashi's double, both from right in front of goal, were much neater moves.

Celtic fans will be driving home for Christmas very happy this afternoon if this level of performance continues in the second half.

For the visitors, they haven't had a lot to cheer about. Stevie May and Nicky Clark are a bit starved up top.

Credit to St Mirren who have clearly looked to unsettle Aberdeen's defence. They got there and are now in charge.

There's an obvious fragility with the Dons and again it has been exposed brutally.

Luck also plays a role and Jim Goodwin must wonder what he's done to deserve the complete lack of it he is currently experiencing.

Mark O'Hara's penalty diverted back off the post and into the net off Kelle Roos.

All of a sudden it's looking like a long afternoon for Aberdeen after taking the early initiative.

St Mirren should be in front here.

Curtis Main stands a ball up the back post, and Jonah Ayunga has a free header six yards out, but Kelle Roos gets across to push the ball over.

That's three goals for Kyogo in four days, and they're all identical. Just a run across at the front post, ball along the deck, clipped over the goalkeeper. They're really good finishes.

After a VAR check, Nick Walsh points to the spot. It turns out the foul from Stewart was inside the box!

Jonah Ayunga is upended on the edge of the box and the Aberdeen skipper is given his marching orders.

A Christmas nightmare for Aberdeen, with Duk on the deck following a late tackle from Ethan Erhahon?

The St Mirren midfielder is booked. Duk is limping heavily, his ankle looks in bother.

He's off for now. But after a few stretches, comes back on.

Reo Hatate hammered in the first, via a slight deflection.

A lovely near-post flick from Kyogo gave Celtic a 2-0 lead...

Celtic are looking sharp this afternoon, both goals proof of that. The first a quick break of play with Reo Hatate not hanging around in bursting forward, while Kyogo's awareness and movement for their second demonstrated a different kind of readiness. Celtic making this look very easy indeed.

Celtic are in cruise control with their two goal cushion.

Spraying the ball around with a fair bit of ease and zipping the ball into the wide areas when they sniff the opportunity to pounce.

St Mirren look a threat when they do get forward.

Curtis Main works space nicely and let's fly, but a white Aberdeen jersey gets a block in.

Aberdeen look unconvincing when the ball is launched in their box.

It's identical to Kyogo's goal against Livingston the other night, that run to the front post. A low cross and he just flicks it in.

Aberdeen have been in control since the goal.

Passing it about nicely, while St Mirren try to get the ball back. Early days, though.

That is exactly what Aberdeen needed.

Matty Kennedy had already fired a warning just prior to his thunderous opener. It was an absolute beauty.

For all that has happened this week, Aberdeen have scored some top quality goals in their last two games.

That's taken individual responsibility, confidence and belief to make something happen.

The next step is to build on that and not take a step back.
