Red Star Belgrade 2-1 Rangers (2-4 agg): Scottish champions through to first European quarter-final in 14 years

Ryan Kent's second-half finish restored Rangers' three-goal cushion in the last-16 tie

Rangers reached their first European quarter-final in 14 years after a resilient second-leg showing at Red Star Belgrade sealed a landmark Europa League aggregate victory.

But Ryan Kent's deflected second-half finish ended the tie as a contest after Allan McGregor made several key saves.

Ben Nabouhane grabbed a late Red Star consolation from the spot.

Rangers were rocked for spells with the aggregate scoreline at 3-1, but yet again their veteran keeper was on hand to deliver another outstanding performance in his 99th in European for the Scottish champions, ensuring their advantage was not reduced further.

The Ibrox side will discover their last-eight opponents in Friday's draw, the first time they have reached this stage since their journey to the Uefa Cup final in 2008.

• Reaction & as it happened

Prior to kick-off, only one team in Europa League history - Valencia against Basel - had overturned a deficit of three or more in the first leg of a knockout tie - and Rangers were in no mood to be the second victim.

In a cauldron of noise at Belgrade's 'Marakana', the Ibrox side were calm and composed in the early exchanges, with Alfredo Morelos first to test the goal with an ambitious strike from the right of the Red Star box.

But the hosts clicked into gear after 10 minutes and ordered Rangers to show a huge test of character when Ivanic drilled in an opener on the night.

Guelor Kanga delivered a short corner into the box and hesitant defending from the away side allowed the ball to bounce before the 28-year-old took one touch and hammered past McGregor.

Rangers' impressive early work quickly turned to panic as Red Star came close to adding a quickfire second when Ivanic struck across McGregor on the break, but the Rangers keeper's vital left hand tipped the goal-bound effort around the post.

Red Star boss Dejan Stankovic said his side would be "twice as strong" in the return leg, and Rangers were getting a taste of that as a raucous crowd roared on every home attack.

The visitors looked spooked, but the Serbian hosts' desperation for more goals provided space on the break for the Ibrox side to expose.

Morelos spurned a three-on-two opportunity when he failed to find Kent with a pass, and that was almost immediately punished when Ohi Omoijuanfo nodded a back-post header into the arms of McGregor straight up the other end.

Another opening for Morelos was dragged wide of the far post, with Red Star again seeing a chance fall their way in the aftermath.

The Rangers backline failed to deal with a long ball as Milan Pavkov was able to pick up the scraps, but the Red Star forward watched his finish trickle by the left-hand post when the forward ought to have found the net.

The Scottish champions have found themselves involved in basketball-like affairs in this season's knockout stage, but as the half progressed the game became stop-start, allowing Van Bronckhorst's men to take breath and slow the game down.

There was still time for McGregor to make a crucial first-half intervention when Cristiano Piccini's curling effort was tipped over by the 40-year-old - a crucial moment in the tie - and the Rangers stopper was again at full stretch to react to a Red Star corner early in the second period.

There was then a one-on-one opportunity for Omoijuanfo, who outmuscled Calvin Bassey but overhit a simple pass to Pavkov, who was lurking for a simple tap-in.

It was a sliding-doors moment for Red Star as Glen Kamara's pass in behind the home defence soon after saw Kent race clear and guide a deflected finish over Milan Borjan.

That goal sapped the energy out the home crowd, but their side continued to pepper the Rangers goal as Ivanic had an effort drag past the back post and a header parried to safety by McGregor in quick succession.

The resulting corner saw McGregor make a rare fumble from Kanga's long-range effort, but the keeper recovered to gather Nabouhane's rebounded effort which really should have burst the net.

Kemar Roofe, who came on for the injured Morelos, was denied a fifth for Rangers when the substitute forced Borjan down to his right.

But it would be Red Star who would have the last say when Kamara gave away a penalty for a step on the toe of Filippo Falco.

Nabouhane converted low to the left, sending McGregor the wrong way, but it was no more than a consolation as Rangers progressed on another memorable European night for this set of players.

Man of the match - Allan McGregor

The evergreen 40-year-old was absolutely crucial again for his side, making a string of stunning saves at vital times in the game

What did we learn?

Competition favourites Borussia Dortmund? Tick. Serbian champions Red Star? Tick. Who next?

Champions League calibre opposition in Barcelona, Atalanta and RB Leipzig potentially lie in wait for Van Bronckhorst's side - but would anyone fancy being paired with this Rangers side, who continue to shine on the European stage?

A two legged quarter-final adds more minutes and mileage to a season-defining April, but the Ibrox club must embrace a first last-eight venture in 14 years.

With Dortmund and Red Star side dispatched in empathic style, anyone with allegiances to Rangers deserves to dream.

What's next?

Rangers turn their focus to reclaiming their Scottish Premiership title on Sunday when they travel to bottom side Dundee (12:00 GMT).
