Rangers have been shown that a Europa League upset against Borussia Dortmund is certainly not impossible as the Bundesliga side slip to a disappointing defeat at the hands of Hertha Berlin.
Currently second in the German top flight, the talent-strewn squad fell to their fifth defeat in 17 league games this season by succumbing to a 3-2 loss in Germany’s capital.
The result leaves them nine points off league leaders Bayern Munich, who sent an emphatic title message by humbling Wolfsburg 4-0 earlier in the weekend.
Rangers are set to visit Dortmund in February and fans can look forward to welcoming the club to Ibrox for the second leg in a Europa League Knockout Round tie to savour.
But despite the potential of Erling Braut Haaland, Axel Witsel, Marco Reus and co visiting Glasgow, results such as this prove that the Champions League drop-outs are anything but invincible.
Rangers watch on as Borussia Dortmund fall to Hertha Berlin defeat
BVB would eventually succumb to defeat against Hertha Berlin despite taking the lead in the first half through German international Julian Brandt.
The attacking midfielder deftly lifted the ball over the top of the Hertha goalkeeper after both sides had missed a host of chances and Berlin even had a goal controversially ruled out for offside.
Dortmund would take the lead into halftime but the match would flip completely in the second, Ishak Belfodil rolling the ball under the keeper after a powerful run to draw Hertha level.
Only six minutes later Marco Richter had Hertha in front with his first goal of the game, a lovely dug-out effort which sailed in the top corner past Marwin Hitz from the edge of the Dortmund box.
The forward would then hammer home his second with a rifled effort Dortmund played themselves into trouble and the ball rebounded out from keeper Hitz initial save.
Substitute striker Steffen Tigges would then nod in a powerful header with seven minutes to play but Hertha Berlin held on to secure the victory.
Rangers will have one eye on everything Hertha Berlin did to nullify Borussia Dortmund and can take optimism from the imperfect and often inconsistent performances of the German giants.
Rangers manager Giovanni van Bronckhorst has also been talking about a potential reunion with a £100m-rated Dortmund wonderkid.
