Wolves boss Mick McCarthy has admitted he is struggling to bring in players who can make an instant impact in the Premier League.
Following Saturday's home defeat to Aston Villa, Wolves find themselves in the bottom three for the first time this season and are facing a battle to avoid the drop.
McCarthy has the backing of club owner Steve Morgan but is fully aware of the pitfalls of the January transfer window.
"If there was a player there for us to sign, and it's one we can do, then he (Morgan) would be supportive," said McCarthy.
"But it is difficult to get anyone - and particularly anyone who fits straight into the team.
"Trying to get someone in, who has been in and around the Premier League and understands it, is very hard.
"There is nothing imminent but we will keep on trying. It's got to be someone who will improve the team, not just to fill up the squad."
McCarthy also gave his support to Karl Henry, who is facing a three-game ban after being sent off for aiming a kick at Villa winger Marc Albrighton at the weekend.
McCarthy added: "There is no excuse for it and Karl gets a kick up the backside for doing it. He's apologised to me and the players.
"But he hasn't made many mistakes in the last five and a half years at Wolves and has been brilliant for this club. He gets my support for the next 13 games he will be available for."
