Birmingham boss Alex McLeish has admitted to holding an interest in Milan Jovanovic, but feels he is unlikely to land the striker.
The Serbia international is currently with Belgian champions Standard Liege.
Reports have suggested that the Blues will make their move during the January transfer window, but McLeish has been quick to curb expectations.
"I've always admired Jovanovic, but whether he's a player who can come here or not remains to be seen," said McLeish.
"I'm sure he has got many admirers and it's a shame that something like that has got around because we try to keep as much private as possible.
"I feel uncomfortable talking about players. From a fans' perspective, to see us linked with players like that is brilliant, but I have to respect the fans.
"I could name another six big names that would excite them but if we don't get them, they are disappointed.
"We have got to keep our business private and move forward, but we will see if something can be done there. I don't know though. It's doubtful."
