Wolves boss Nuno Espirito Santo says the club will only sign a "special" player during the winter transfer window.
And Nuno says he will only bring in somebody who can dramatically change his team.
"When you bring someone, you have to be careful what you bring," he said.
"It has to be something we don't have already.
"If someone comes, they have to bring something really, really special, because we already have something good."
