Maurice Edu insists Rangers have already shown they can survive the loss of a top goalscorer and still deliver the goods.
And the midfielder believes that will be the case again if Kenny Miller opts to quit the Scottish champions, either this month or when his contract expires in the summer.
Rangers have accepted an offer from Birmingham and the striker is holding talks with the Midlands club, as well as Italian outfit Fiorentina, with a departure appearing increasingly likely.
Miller has successfully filled the void left by star striker Kris Boyd's exit in the summer by netting 22 goals so far for Rangers, and Edu claims life will go on without him too.
He said: “People were questioning what would happen to the team last season when guys like Kris Boyd left after scoring so many goals for us.
“This is a similar situation, when the team has to come together and be able to put together complete performances. Kenny has been a big player for us. He has scored a lot of goals for us so far and he has been our go-to guy in terms of scoring goals.
“Like any situation, whether a player leaves or gets injured, whatever the case may be, it's an opportunity for another player to step in and try to fill that void and step up to the plate and show what he's worth to the team.
“I don't know what the situation is right now but if Kenny does leave, it's an opportunity for another guy to come in.”
Miller was left out of the squad for Monday night's 3-0 Scottish Cup win against Kilmarnock, with the goals shared between Lee McCulloch, Kyle Lafferty and Steven Whittaker.
And Edu is confident the current squad is good enough to chip in with more goals if Rangers are unable to recruit a replacement should Miller seal a January move away from Ibrox.
He added: “I think we have the personnel where there are guys who can step in and score goals.
“Kenny would obviously be a big, big loss for us because he has scored quite a few goals for us already this season and he has been our target man.”
Rangers have been rewarded for their efforts against Kilmarnock with a mouth-watering fifth-round tie against Celtic at Ibrox.
