Dundee United boss Craig Levein fears losing Barry Robson.
The Scotland international, who has been linked with a move to Celtic, fired home his ninth goal of the season when there appeared to be little danger to give the Terrors a 1-0 Scottish Cup victory over Clyde on Wednesday.
And Levein worries the Bhoys will firm up their reported interest in Robson.
He said: "Of course I do.
"I'm the manager of the team and he is the best player. But nobody has made any offers and we'll cross that bridge when we come to it."
