Rangers won 4-2 at Borussia Dortmund on Thursday to take control of their Europa League knockout round playoff encounter.
In the 38th minute, Glasgow took the lead thanks to a penalty kick from James Tavernier.
Then, in the 41st minute, Colombian forward Alfredo Morelos extended their lead off a Joe Aribo pass.
This occurred when he touched in from close range an attempt by the Super Eagles player, following a well-worked corner-kick routine made simpler by Borussia Dortmund’s weak marking.
In the 49th minute, a thundering first-time goal from beyond the penalty area by John Lundstram placed Rangers in dreamland.
England midfielder Jude Bellingham quickly pulled a goal back in the 51st minute, smashing into the net from outside the box to give the hosts a foothold in the game.
Rangers took no time to respond, restoring their three-goal advantage three minutes later.
That was after an own goal from defender Dan-Axel Zagadou, who deflected a strike from the lively Morelos beyond the reach of goalkeeper Gregor Kobel.
Borussia Dortmund salvaged some hope for next week’s second leg at Ibrox with a piledriver from Raphael Guerreiro in the 82nd minute.
Defender Mats Hummels tried to pull another goal back deep in stoppage time but could only produce a wayward shot which flew over the bar.
A reduced capacity due to coronavirus restrictions made for a subdued atmosphere at the Signal Iduna Park.
Only 10,000 fans were present in the stadium where one stand is nicknamed the Yellow Wall due to the noise emanating from it.
Giovanni van Bronckhorst’s side made the most of the reduced home crowd and were utterly dominant against Borussia Dortmund, who are second in the Bundesliga.
The German side are usually very reliable at home, having won 12 of their 15 home games in the league and in Europe.
They were still missing injured top goalscorer Erling Haaland, who could return in time for the second leg.
That is where 50,000 fans are set to pile into a full-capacity Ibrox, hoping to see their side complete the job against one of Europe’s powerhouses.
