But John Souttar knows his side will again find themselves slumping from heroes to zeroes if they fail to build on this latest period of promise.
It’s been a campaign of false dawns for the Ibrox outfit with big European performances repeatedly followed by deflating, devastating domestic results.
They have now beaten Celtic for the second-successive derby, yet remain 13 points behind their Treble-chasing foes.
But Souttar is hoping yesterday's sensational show at Celtic Park will finally prove to be the turning point.
The Old Firm triumph comes on the back of their gruelling two-game shootout with Fenerbahce.
They were forced to go the distance on Thursday night as Jose Mourinho's Turks overturned the 3-1 win Rangers had sauntered to in Istanbul, surviving a test of nerve to progress on penalties.
But with just a couple of days to rest their weary legs, Barry Ferguson's men found the energy to go wire to wire again, with Hamza Igamane’s 88th-minute winner sparking bedlam in the newly restored away section.
Rangers will now have a chance to rest up over the international break and Souttar hopes that winning feeling will linger a little longer this time.
He said: "Over the last week and a half we've had three big results but that's all it is really.
"We have to find consistency throughout the season. There's no point dwelling on today and getting too far ahead of ourselves. We have to enjoy today because we deserve it but that's as far as it goes.
"It was a good feeling. It was obviously frustrating losing two goals having been two up.
"But it’s always nice to get a win late on, especially with the fans back in, so it’s a good feeling.
"This season has brought a lot of frustration but that means we won't get carried away with this one result because there's no point in doing it on a one-off. You need to keep doing it through the season.
"That's what the gaffer's been drilling in to us, how important league games are. We have a lot to prove domestically.
"We need to keep that consistency. We've had big results before in the league and we've not backed it up.
"In Europe, it's a great opportunity for us. Thursday kept the season going and you saw how Ibrox was, so the more nights we can have like that the better." The more of these results Ferguson manages, the more likely the caretaker gaffer is to be talked up for the job on a permanent basis.
He's refusing to get involved in that chat and so is Souttar.
But the Scotland defender has certainly been impressed by the way the former Ibrox skipper has performed since taking over from Philippe Clement.
He said: "The gaffer is big on character...
