Wolves boss Mick McCarthy has admitted he is concerned over the long-term future of goalkeeper Matt Murray.
The 25-year-old custodian has 18 months left on his current deal, but is stalling on signing a new contract at Molineux, which could prompt McCarthy to cash in on the former England Under-21 international.
"There isn't a better goalkeeper in our league than Matt," McCarthy told the Birmingham Mail. "If he had to play in the Premier League he would comfortably.
"Matt is under contract for another 18 months so it's not a big issue at the moment. I've had a discussion with him and he has not refused to sign another contract.
"There's no bone of contention with me and Matt. But if, in six months' time, he has not signed a contract, there's no way we will let it run out.
"And, of course, if he doesn't want to sign it then he'll be sold. That's the football world, I'm afraid."
