The Gers are 2-0 down to Union Saint-Gilliose after a poor display last week in Belgium, but at home, they are a different prospect.
Last season, the likes of RB Leipzig and Borussia Dortmund were dispatched by Rangers on their patch, and they must do it again.
If they can overcome the deficit, they will face Monaco or PSV in the next round.
But first, they must play a lot better than last week and try to keep the Champions League dream alive by pulling off another magical Ibrox night.
They have done it so many times before and must now do so again or the Europa League will await once more.

The big news for Rangers is that Ryan Kent is fit and available.
The 25-year-old missed the first leg last week but could come straight into the starting XI.
Fashion Sakala and Alfredo Morelos are also regaining match sharpness and could be thrown in by Giovanni van Bronckhorst.
However, the hosts will be without Ianis Hagi, Kemar Roofe and Nnamdi Ofoborh.
Hagi is recovering from knee surgery, Roofe has a knock and Ofoborh has been out for a year due to a heart condition.
Rangers v Union Saint-Gilliose: What has been said?
Rangers boss Giovanni van Bronckhorst: "We want to stay in the Champions League.
"The first game wasn't the result we wanted but we have a home game tomorrow that we can change the result.
"My objective and desire is to be in the Champions League again next week. Last week is not our normal level in Europe, our standards and performance have to be on a high level tomorrow.
