Ally McCoist believes the 4-0 win over Hibernian proves Rangers can survive even if Nikica Jelavic leaves the club.
The striker, who missed Saturday's game at Ibrox with illness, has attracted the interest of a number of clubs during the January transfer window.
With Jelavic missing David Healy seized his chance in the starting line-up, as did fellow striker Sone Aluko. New skipper Steven Davis netted the other two goals.
McCoist does not want to lose his top goalscorer, but given Rangers financial situation he knows it could be out of his hands.
He said: "There's not just life beyond Nikica, there's life beyond us all.
"There are bigger players who have left this club and the club always goes on. That's the most important thing because the club is the most important thing.
"Nikica, if he went, would be a big loss. He's a fantastic player and he has been a great talent here.
"But, as you saw today, we scored some really good goals. Nikica also didn't play against Motherwell and equally we did very well. That's just two examples.
"I'd also like to tell you I wouldn't like to lose him. Of course I wouldn't because he's a good player.
"But I understand the economics of our club and I understand the economics of football.
"Sometimes they dictate and determine what happens rather than other things."
Rangers were reported to be interested in a move for Polish striker Pawel Brozek, but he is now thought to prefer a move to rivals Celtic.
The Ibrox boss said: "It's a disappointment but I would use the word 'target' a little bit carefully.
"He's a player we were looking at and - I won't lie to you - we were sort of interested in but there were no specific bids made and I didn't have any contact with the player or the agent.
"He's absolutely well within his rights to do what he thinks is best for himself. There's no doubt about that.
"It would take a lot more than that to really disappoint me to be honest."
Jorge Claros also looks unlikely to be joining Rangers, despite impressing on his trial spell at the club.
McCoist added: "Where we are at the moment with Claros is we are not in a position to offer him a contract yet.
"We will sit down again tomorrow and Monday to discuss the situation. He has done well and he has looked comfortable.
"Being 100% honest, we are slightly better covered in that position than we are in one or two positions.
"That's not to say that I wouldn't like him on board or I wouldn't take him.
"I do like him and wouldn't mind getting him on board but I think we do need to prioritise other areas of the park."
