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.

More changes as Mehdi Merghem comes off the United bench and Haissem Hassan is on for his Celtic debut.

Jesse Randall and Sebastian Tounekti are men making way.

Just on the park, Yoro gets a yellow card for a late challenge before Celtic follow suit with three changes.

Forrest, McCowan and Murray are on, replacing Hogh, Nygren and Trusty.

A triple change for deflated Dundee United, with Metsoko, Yoro and Bennie on for Eskesen, Sapsford and Rose.
