Lyon's Karim Benzema is expecting to face a Rangers defensive wall at Ibrox on Wednesday night.
The two teams go into the game level on seven points each, but Rangers know that a draw will be enough to send them through as they have the better head-to-head record after beating the French champions 3-0 earlier in the campaign.
Rangers also have the added bonus of having had the weekend off, whilst Lyon were beaten 1-0 by Caen on Saturday.
However, French international striker Benzema believes that this result will have no bearing on the UEFA Champions League game, and that Lyon are confident of getting the result they need.
"We have a big match to play at Glasgow. It's a final and we will do all we can to qualify," he told Lyon's official website.
"We received a warning in the home game and now it's down to us to go and win this match."
Lyon president Jean-Michel Aulas shares Benzema's confidence and is convinced that his side will be too strong for Rangers.
"Personally I am convinced we will do what we have to do," he said.
"Scotland lost to Italy at home and I am sure that incident will have an impact on them (Rangers)."
Aulas admitted though that preparations for the game had not exactly gone according to plan after the surprising defeat at the weekend.
"We wanted to prepare the team for Glasgow by rotating it, but it (the Caen game) did not end as we wanted it to.
"We had no injuries and that's important because the most crucial game is the Glasgow game."
