New Tranmere boss Micky Adams has bolstered the clubs attacking options with Cardiff's Danny Johnson on a one-month loan.
Full-back Maynor Figueroa has returned to Wigan on a one-month loan deal from Hull.
Paul Lambert insists Aston Villa owner Randy Lerner remains fully committed to the midlands club ahead of Tuesday night's crucial Barclays Premier League relegation battle with visiting Newcastle.
Villa manager Lambert senses no waning of Lerner's interest despite limited funds available for new players during January - a stark contrast to the big sending of the Magpies.
Lerner has spent more than £250million in six-and-a-half years at Villa including £23million on new signings last summer.
There will be no spending along those lines during the current transfer window but Lambert was aware of the need to work within certain financial parameters when he replaced Alex McLeish.
When asked about the current limited transfer funds, Lambert said: "I don't know whether [it's because of] the outlay since Randy's been here, putting all that money into the club.
"But you can't spend something if it's not there. I think he has got money, or his own wealth, entirely his own wealth.
"I think what's happened is the club spent millions a couple of years back. It can't do that, there's absolutely no way it can do that.
"Finance dictates a lot of things. Finance will always dictate a lot of things."
Lambert added: "The one thing is he's not washed his hands of [the club].
"Anyone who puts that level of money in over the years...it's been an incredible amount of money.
"I think people are looking for things because he doesn't come [to all the games].
"If he has got other commitments, that's entirely up to himself, if he has got other things on. But he's definitely behind the club. He wouldn't have done what he's done if he wasn't committed to it."
Lerner has also reiterated his support for Lambert ahead and is convinced he can steer Villa through their current battle to avoid the drop.
He also has faith in the Scot to help Villa achieve their longer term goals of stability and being a competitive force.
Lerner said: "In the time that I've come to know Paul, what is clear above all else is his strength of character and belief in his approach to football.
"I would reiterate that Paul has achieved success at many levels of professional football and I believe, given support, he will continue to do so for us."
"Fortunes can shift quickly in this game and a sense that one has it right can become grave doubt in a matter of a few games.
"The Villa board knew that with Paul we would begin to address the club's multi-year lack of competitive stability by reshaping the squad with seven new signings in the summer.
"It has been rewarding at times this season although certainly frustrating as well, particularly recently."
