Rangers reached the Europa League last 32 for the second successive season, with a game to spare, after fighting back twice to defeat Standard Liege.
Steven Gerrardâ€™s side, so strong defensively this term, conceded from crosses on two occasions before the break when Maxime Lestienne, then Duje Cop, breached Allan McGregorâ€™s goal.
Connor Goldsonâ€™s header, then a James Tavernier penalty, had Rangers on terms at the interval, before Scott Arfieldâ€™s second-half strike ensured the win that keeps them top of the section.
Gerrardâ€™s team travel to Poland to face Lech next Thursday knowing they will win Group D if they match Benficaâ€™s result against Standard.
Only a win would do for the Belgian visitors, who travelled to Ibrox with two wins from their previous 10 games.
And they were rewarded for a positive start after Cop beat Goldson on the left before guiding a low cross into the box for Lestienne to finish neatly.
Rangers just could not get into the attacking flow that had been key in guiding them to a 23-match unbeaten start to the campaign, as Standard continued to press and pose a greater threat.
However, as the game approached the half-hour mark, the hosts began to show signs of finding their rhythm.
Both Ryan Kent and Alfredo Morelos tried their luck before Borna Barisicâ€™s outswinging corner was met by Goldson, who headed home superbly into Arnaud Bodartâ€™s top-right corner.
But just 46 seconds after getting themselves back into the game, Rangers found themselves behind again as Collins Faiâ€™s inch-perfect delivery from the right was bundled in by Cop, who clattered into the back post in the process.
The hosts responded well as Arfield lashed a volley over before Kemar Roofeâ€™s strike struck a hand in the Standard box, allowing Tavernier to convert his ninth spot-kick of the season just before the break.
Similar to the first period, the Belgian outfit were the brighter of the two in the opening stages of the second half as Allan McGregor - setting a new record of European appearances for Rangers - saved well from close range after Abdoul Tapsoba was slipped through on goal.
However, with the best move of the game, Rangers would take the lead for the first time as superb build-up resulted in Kent crossing low from the left to find Arfield steaming into the box to smash home from 12 yards.
The goal sparked the hosts into life, and they could have won the game by more if it not for some outstanding saves from Bodart in the Standard goal.
The goalkeeper was forced into a series of fantastic stops from free-kicks by Tavernier and Barisic, before saving another Goldson header and a close-range effort from Roofe.
The win extends the Ibrox clubâ€™s unbeaten run to 24 games and next Thursday they have the opportunity to top the group if they can match second-placed Benficaâ€™s result.
Man of the match - Scott Arfield
What did we learn?
Gerrardâ€™s side had only found themselves behind in two of their previous 23 games this campaign, so trailing twice to a bright and aggressive Standard side was a new test. However, despite looking disjointed in spells, the response from the hosts was ruthless as they yet again found a way to win.
Since his appointment, Gerrard has always been recognised as a success in Europe, but for the third consecutive year there has been improvement.
This is the first time he has guided his side to the knockout stage with a game to spare he has the chance to top the group next week, something he is yet to achieve.
- Rangers have lost just one of their last 22 home matches in Europe, including qualifiers (W15 D6).
- Standard have lost four of their five Europa League group stage games, having lost just four of their previous 16 (W6 D6 L4).
