First booking of the night as Aleksander Dragovic brings down Alfredo Morelos then aims a volley of abuse at the referee.

Quote MessageGreat run and pass, and then it's just one trick too many. How Red Star haven't scored more is beyond me. Rangers have ridden their luck so much tonight.

More work for Allan McGregor as he gathers a header from Milan Gajic.
The 40-year-old might need an ice bath to ease his aching muscles after this one. Or maybe he'll make do with a cold beer.

Ryan Jack and Joe Aribo are withdrawn, with James Sands and Scott Arfield on to bolster the Rangers midfield.

One for the cameras as Allan McGregor pushes the ball behind theatrically. It almost backfires as he has to make two more saves in quick succession, the second of which is a smothered stop on the line from El Faroud Ben, who really should have burst the net after meeting a rebound six yards out.

It looks like Milan Ivanic uses an arm to control a pass over the top before drilling just wide of the far post.
I think the VAR lads would have ruled that out if it had sneaked in.

Ohi Omoijuanfo has looked a bit cumbersome in attack for the home side this evening and the big Norwegian is now replaced by El Fardou Ben, who was lively as a sub in the first leg.

The away end goes bonkers as Ryan Kent grabs the goal they clearly believe takes them into the last eight. All of a sudden, a few hundred Rangers fans are making themselves heard over the 50,000 home supporters.
That goal looks to have deflated the Red Star players.

Just after that Ryan Kent goal, the home side replaced right-back Cristiano Piccini with Milan Gajic.
It looked like Piccini pulled something when trying to catch up with Kent.

Connor Goldson heads a cross straight into Ohi Omoijuanfo but the Red Star striker can only slash wide with his first-time effort.

Quote MessageThat's the first time we've seen Kent in open territory. He sucks the defender in, and then gets a little bit fortunate with the deflection. It comes at a great time for Rangers, because they were under huge pressure.
Ryan Kent
What was that about Ryan Kent having an off night?
Glen Kamara sets the winger off and running and a stretched home defence can't cope as he cuts into the penalty box and his deflected shot loops over the keeper.
Red Star Belgrade 1-0 Rangers (1-3)
Ohi Omoijuanfo has a swing at a shot inside the Rangers penalty box and it takes a slight deflection off Connor Goldson, but Allan McGregor watches it all the way.
Red Star Belgrade 1-0 Rangers (1-3)
Rangers need to get hold of the ball to alleviate this pressure but too many passes are going astray and Ryan Kent, so often a great outlet in attack, is having a bit of an off night.
Red Star Belgrade 1-0 Rangers (1-3)
Rangers are hanging on here...
Ohi Omoijuanfo races in behind but Calvin Bassey does well to catch up and knock the striker out of his stride in the penalty area.
Mirko Ivanic is there for company with an open goal at his mercy, but an off-balance Omoijuanfo can't find him with his pass.
A huge let-off for the visitors.

Quote MessageI think this might be the best save of the night - it comes at him so quick. It might not be going in, but if he doesn't get a touch, then there's a Red Star player waiting to tap it in.

Another fabulous stop from Allan McGregor!
The visitors are shaky at a corner again and a near post flick is creeping in before the goalkeeper gets fingertips to the ball.
Red Star Belgrade 1-0 Rangers (1-3)
Rangers off the hook as the ball bounces up off the arm of Leon Balogun and the referee gives a foul the other way. Just a yard or two outside the penalty area.

Here we go again.
No changes for either side.
