Rangers boss Walter Smith has admitted he faces a tough task to replace Dado Prso at Ibrox.
Prso looks set to leave Rangers at the end of the season because of a long-standing knee problem.
Smith is already drawing up a list of targets to replace Prso, but he accepts it will be hard for anyone to fill the Croatian's boots in Glasgow.
"It's going to be difficult to replace him," said Smith.
"We would have liked him to carry on, which is a measure of how highly we regard him.
"Front players are not easy to find. We will have to search for that.
"We just have to get on with it and hope that we can fill the gap left by Dado.
"I've only been here for a few months but, having seen him play previously, I could see that he was a good player.
"First and foremost, he is an exceptionally good player and I think everyone appreciates that.
"He also has a terrific character and handles himself very well within the dressing room.
"It's not always easy for foreign players to come and impose themselves on a dressing room but he has handled that right from the very start.
"He's got a great personality and is very lively and he has a great willingness to win and that's the thing that has made him popular with everyone.
"Supporters see that every time he goes out onto the pitch, he gives everything he's got.
"He has shown that especially this season when he has been toiling with a knee injury. A lot of players probably wouldn't have put themselves up for selection if they had that injury."
Northern Ireland and Leeds striker David Healy has been linked with a possible move to Rangers, but Smith was remaining coy on his transfer targets.
"It's always interesting to read the speculation," added Smith.
"You go to a game and you're linked with one player or another.
"We need a few players, there's no doubt about that, and everybody is free to speculate on who those players are going to be."
