The main thing was to get through for Celtic. [The conceded goals] are something to work on for Martin O'Neill.

It's so important they keep scoring goals, Nygren is a fantastic player in that area.

Job done for Celtic.

Martin O'Neill's side are through to the Europa League knockout play-offs, where they will play for a place in the last 16.

I don't think Danny Rohl will be too dissatisfied with his side's performance on the whole.

They have been severely punished for some slipshod defending in the final 20 minutes of the first half.

Otherwise they've been quite neat and tidy but the familiar failing is a lack of cutting edge when it matters.

Three minutes added in the east end of Glasgow.

Kieran Tierney is off for Dane Murray.

That should be four for Porto and good night for Rangers.

Attacking on the counter, Borja Sainz flies up the left for the hosts. He cuts inside, dragging defenders with him, before laying off to Pepe.

There's not enough power on the pass and the winger has to take a touch, before firing a tame effort at Butland.

We've hit 87 minutes at Celtic Park.

Atmosphere isn't up to much, but the remaining fans at Parkhead are about to watch their team progress in the Europa League.

Vasilis Barkas is scrambling to claw away a Celtic cross and just about gets there at his back post.

A superb last-ditch block from Liam Scales denies Utrecht what looked like a certain third.

Jack Butland gets dispossessed in the box, but out wide. The ball comes in and John Souttar clears away, just a yard or two in front of his own line.

A bit of a dicey moment for Rangers.

This still doesn't feel entirely comfortable for Celtic. There isn't total control there.

Utrecht actually do quite well to get to Celtic's third, but attacks just fizzle out so easily.

Rangers enjoying a spell here. A cross from the right picks out Max Aarons at the back post.

He heads it into Bojan Miovski, who heads into the air again, and Diogo Costa is out to punch clear.

It just wouldn't sit nicely.

This game at Parkhead seems to have calmed down a bit, which will suit Celtic with 15 minutes remaining.

As long as they win, they're through.

Double change for Rangers now, making their final changes of the night.

Thelo Aasgaard and Mikey Moore are on, with Youssef Chermiti and Findlay Curtis off.

Curtis has probably had Rangers' best moment tonight. Another impact from the youngster.

Utrecht are after a third, but Gjivai Zechiel slices well wide of the near post.

James Forrest and Kelechi Iheanacho are both on for Celtic, with Sebastian Tounekti and Daizen Maeda making way

Rangers have had plenty of the ball in the second half but unfortunately when they've got into good areas it's been Max Aarons in the inside left position and frankly that's not his strong suit.

Danny Rohl has made a few changes and Rangers are now four at the back. No doubt he has Sunday's game against Hibernian in mind with some of the players he's replaced.

Nico Raskin tries from distance, but Diogo Costa manages to palm behind.

A rare foray forward from the visitors.

Bojan Miovski and Oliver Antman are on for Rangers, with Emmanuel Fernandez and Djeidi Gassama off.

Wonder how that'll change the formation...
