We'll call it a day here, with Celtic, Aberdeen and Ross County joining Kilmarnock in the last eight of the Premier Sports Cup.

Join us for the four remaining matches on Sunday, along with the draw.

Enjoy your Saturday night.

There has been some kind of VAR briefing from SFA Towers, with the incident involving Kasper Hogh deemed accidental due to it being part of a natural action and then there's the rule book about the handball not coming from the scorer, which scuppers the wriggle room for common sense Jim Goodwin is asking for.

An exasperated Dundee United manager Jim Goodwin tells BBC Scotland: "It was a very similar type of game to last weekend at Tynecastle [another 4-0 defeat]. I don't think the scoreline is a fair reflection of our performance at all.

"The opening 15 minutes or so was very good as far as we’re concerned. The press was good at the top end of the pitch.

"We’re disappointed with how we defend the set piece [for first goal]. The delivery is excellent.

"The second goal is the one that really frustrates me, to be honest. "Don’t get me wrong, I’m disappointed in the fact that two Celtic players can run into our box unopposed, but I thought the whole point of VAR was to stop those type of incidents happening.

"There is no doubt about it, the ball strikes off the Celtic attacker’s hand and lands perfectly for his team-mate to go and tap it into the net.

"I know it wasn’t the guy who handballed it who put it into the net, but surely a bit of common sense needs to prevail there. The handball directly impacts on the goal."

Celtic manager Martin O'Neill is happy to be in the next round of the cup but not entirely satisfied despite the margin of victory.

"I thought Dundee United were in the game, they hit the post [twice] before we scored a goal," he tells BBC Scotland.

"Things like that can change the picture. Overall, I was pleased with a lot of the stuff they produced but there were moments where we were really casual.

"It's a good performance for us considering the last time we were here.

"We have two very difficult matches coming up now in terms of trying to get into the Champions League, the prestige, the finance, everything that goes along with it.

"We will try and be as ready as we possibly can. We are trying to get there, these are big, big games.

"It would be lovely to have had maybe another three games played before then, but it’s not the case. We’re ready for it, we’ll have to be.

"If the support is anything like what they gave in the split last season, it will be extraordinary."

Celtic's next mission is the first leg of their Champions League play-off at home to LASK.

The team from Linz are currently top of the Austrian Bundesliga with three wins from three.

On Friday, they beat SV Ried 4-1, so they are in good form and will have had a bit more rest.

For United, it's two successive 4-0 defeats.

Manager Jim Goodwin will be upset by aspects of his team's defensive work but the scoreline is definitely a harsh one on the balance of play.

The home side hit the woodwork on five occasions, had more shots than Celtic and earned more corners.

They started both halves strongly but were undone by clinical opponents.

That's nine goals in their last two games for Celtic.

It's already looking ominous for the rest...

A goal and two assists for Benjamin Nygren this afternoon.

The smiling Swede tells Premier Sports: "The energy is top and that was a big part in getting the double done last season. We need to keep on going."

Hearts and Hibs at home at the same time, during the Festival / Fringe? A busy old afternoon in store in Edinburgh...

We now know 50% of the teams in the hat for tomorrow's draw as Celtic join Aberdeen, Ross County and Kilmarnock in the last eight.

Sunday's games are as follows...

• Hearts v Inverness CT (14:00)
• Hibernian v Partick Thistle (14:00)
• Stenhousemuir v Motherwell (14:00)
• Rangers v St Mirren (16:00)

Celtic march into the last eight of the Premier Sports Cup.

Auston Trusty, Camilo Duran, Sebastian Tounekti and Benjamin Nygren got the goals for Martin O'Neill's men.

United made a big contribution to an absorbing game and might have to patch up their goalposts after clattering them five times.

Make that five, Mark.

A long-range effort from Mehdi Merghem kisses the junction of crossbar and post.

One of those days for United...

United haven't worked the goalie, they haven't forced a save out of him.

Yes, they've hit the bar and the post four times, but these are the things they need to start looking at.

If this keeps happening, it is going to be a long season.

Camilo Duran loses the ball inside the home penalty box then races like a demon to win it back near the halfway line, earning himself a huge cheer from the travelling fans.

United are taking no chances with a groggy Vicko Sevelj, who is replaced by Pan Camara for the final 10 minutes or so.

Dundee United 0-4 Celtic

Vicko Sevelj takes a sore one as Mika Baur arrives late in an aerial joust and clatters into his back.

United have had a lot of joy from their aggressive high press but another chance goes begging as Abdoulaye Yoro hammers a shot high over the top.

Dundee United forward Daniel Benne is left all alone at the front post from a corner but makes a mess of the free header.
