Rangers boss Giovanni van Bronckhorst saluted his players as they sent Borussia Dortmund crashing out of the Europa League, describing the 6-4 aggregate victory as "a big moment for the club."

Leading 4-2 after a stunning first-leg performance at Signal Iduna Park, the reigning Scottish Premiership champions endured a tense second leg at Ibrox.

Despite James Tavernier's first-half penalty, Jude Bellingham and Donyell Malen reduced the aggregate deficit to a single goal before the break.

Indeed, Malen might have dragged Dortmund level in the tie, but Tavernier drilled in his second just before the hour mark, ultimately booking the hosts' place in the last-16 draw despite Rangers having a third disallowed after a VAR check.

"It is a big moment for the club, we can make a lot of people proud as it was a difficult game again," Van Bronckhorst told BT Sport.

"We were very unfortunate in some moments where we could have cleared the ball. We had to change something to be more defensively solid.

"[Alfredo] Morelos was much stronger in the second half, and we had many more dangerous moments.

"We trained with three different plans for today. We needed to have scenarios in place to be executed, and I'm glad we did.

"We had a great performance; we played them twice and got four points – it’s a great performance. 

"The last 16 is only top teams; we wait for them, and we look forward to the draw."

Dortmund star Bellingham suggested he and his team-mates only had themselves to blame.

"It was brilliant to play in. A good team, a good test," the England international told BT Sport, having created a joint team-high three chances.

"We didn't have the bite we had in the first half. It's just one of those nights, we didn't take all our chances and they took theirs, fair play to them.

"We've let the fans, the staff and ourselves down. If we look at ourselves in the mirror, we'll realise we could've done more."

Bellingham is not wrong. Dortmund finished with a higher expected goals (xG) than Rangers (2.97 to 2.26).

Two-goal Tavernier, meanwhile, revealed that a tactical reshuffle at the break proved instrumental for Rangers.

"We really stepped up in the second half after we changed tactically, it allowed us to progress," Rangers' captain explained.

"The manager told us that we have to follow the runners and tighten it up a bit; that’s what we do in our back five system, and it works for us.

"We are really impressive, the result was pleasing. I always try to get to back post, and I got the goal today.

"This game shows the character that we have in the squad; we have a great squad that can push through."

Rangers have qualified for the round of 16 in the Europa League for a third consecutive season, which is their longest streak of reaching at least this stage in a major European competition since a run of three between 2005-06 and 2007-08 – they reached the final of the UEFA Cup in the last season of that previous run.

Dortmund, meanwhile, have been eliminated in three of their past four two-legged ties in the knockout stages of the Europa League, losing against Liverpool in the 2015-16 quarter-finals, Salzburg in the 2017-18 round of 16 and Rangers this season.

James Tavernier scored twice as Rangers booked their place in the Europa League last 16 with a 2-2 draw against Borussia Dortmund, which sealed a 6-4 aggregate win.

A week on from their brilliant 4-2 triumph at Signal Iduna Park, Rangers had their captain to thank as they secured progression on a frantic night in Glasgow.

Tavernier opened the scoring from the spot in the 22nd minute, but the excellent Jude Bellingham equalised for Dortmund before Donyell Malen put the visitors ahead.

Rangers' resolve returned in the second half, though, with Tavernier drilling in his second just before the hour to end BVB's Europa League hopes.

Bellingham had hit the post as Dortmund looked to deflate the raucous atmosphere at Ibrox, but having withstood the early pressure Rangers went ahead – Tavernier slamming a penalty down the middle after Julian Brandt fouled Ryan Kent.

Brandt wasted a chance to make immediate amends, but Bellingham restored parity when he slotted in after pouncing onto Connor Goldson's poor touch.

Scott Arfield and Alberto Morelos went close for Rangers before Allan McGregor brilliantly denied Malen at the other end in the space of a minute.

McGregor had no chance when Malen prodded past him in the 42nd minute to put Dortmund ahead, however.

Gregor Kobel got down to Morelos' goal-bound shot after the restart, but BVB were made to pay for more dismal defending when Tavernier lashed in at the back post from Joe Aribo's cross.

Dortmund seemed set to regain their lead when Marco Reus rounded McGregor but sliced into the side-netting.

Instead, Rangers were in delirium when Morelos raced through and squared for Kent to tuck in, only for referee Antonio Mateu Lahoz to harshly disallow the goal for a foul on Emre Can after a VAR check, although it ultimately mattered not.
