Leeds United manager Simon Grayson says Fabian Delph 'fits the bill' but has refused to confirm whether he will rejoin the club.
The talented midfielder began his career with the Whites, making 46 league appearances, before joining Aston Villa in August 2009.
He was a regular for Villa in the first half of the season, but has not played since December and is thought to have been made available for loan by Alex McLeish.
Grayson has revealed the club are working towards up to two deals, although he is refusing to confirm who is on Leeds' radar.
"Fabian Delph is a good player who knows about Leeds United because he has been here before," he told the club's official website.
"His name is being bandied around as if he is available for loan. You're not going to draw me on whether we will do it or not, but he's a player, along with others, that would fit the bill.
"He fits the bill because he knows what this club is about and what it means to play here, but we're working towards one or two deals and I will refuse to name them."
The Elland Road boss knows it is difficult to do business in January, but has reiterated the club are working hard behind the scenes on bringing in fresh faces.
"It's always difficult at this time of year, but we're working extremely hard to achieve what we want to do," he continued.
"We've been linked with a lot of players over the past few days and weeks and we are looking to strengthen, but what you have to do is bring in someone who will make you better.
"There is no point in bringing in players who are going to sit on the bench and be around the squad - you want players who can come into the first team straight away.
"That's what we have to work at and if it means hanging on a few more days or a week I will do that."
A number of players have been linked with the Leeds exit door and Grayson is hoping to move on players who are not part of his long-term plans.
"We're looking to do things in that direction as well," he continued. "There's been enquiries and clubs will be like us in considering 'can they take so-and-so?'
"It changes from day to day. Teams might be looking for something one day then a completely different position the next depending on circumstances.
"We've got some who we wouldn't stand in their way, but anyone leaving the club will be on our terms and no one else's."
