Steven Davis believes Rangers need at least four points from their UEFA Champions League double-header with Unirea Urziceni if they are to reach the last-16.
The Gers have picked up just one point from their opening two European games and know they must beat Dan Petrescu's men at Ibrox on Tuesday if they are to keep their Champions League dream alive.
The Scottish champions were outclassed 4-1 by Sevilla at home last time out but Davis knows three points against Urziceni, who also have one point from their two games so far, puts them right back into the mix.
Walter Smith takes his side to Bucharest next month before welcoming Stuttgart to Glasgow and finishing the group with a trip to Sevilla.
"We need four minimum if we are looking to progress. The home games are vitally important in this competition," Davis said.
"And, if you are going to progress, you need to pick up results on the road as well. We didn't beat Sevilla and that makes the game tomorrow night all the more important for us."
Despite their low points return Rangers have reserved some of their best football for the Champions League this term with a strong second-half showing at Stuttgart and a decent opening 30 minutes against Sevilla.
Davis acknowledges this and admits that the players look forward to Champions League games with excitement rather than apprehension.
"There is a lot more to come from us this season," he added.
"We haven't been playing to the best of our ability. The European games are ones the boys have been up for and looking forward to and we have played some of our best football of the season so far in this competition.
"They are great nights to play in and all the boys look forward to the European games especially at home when the fans get behind us.
"We want to stay in this competition for as long as possible and get as many games under our belt as possible."
Rangers will be boosted by the return of arguably their most impressive performer in Europe this season, Madjid Bougherra, after he missed the game with St Johnstone at the weekend having returned late from international duty with Algeria.
"Madjid has been a big player for us this season and has put in a couple a good performances in the Champions League so far and he looks forward to the games. We are delighted to have him back," the midfielder enthused.
