Leeds United will need to strengthen if they are to challenge for promotion this season.
Whites boss Thomas Christiansen has his work cut-out at Elland Road, with his side currently in the midst of a woeful run of form that has seen them lose four of their last five Championship outings.
Leeds made a superb start to their 2017/18 campaign, and were sitting comfortably at the top of the table just last month, before they embarked on their miserable run.
And Christiansen will surely be looking to bolster his options during the January transfer window.
The problem for the Whites boss is that it is debatable whether he will be backed with adequate funds from the west Yorkshire outfit's owners, so he might just have to be thrifty in the transfer market.
Here are three potential free transfers he should consider signing...
The 34-year-old Frenchman has been without a club since his release from Manchester City in the summer, but he still has a lot to offer at the highest level.
Sagna has maintained impressive fitness levels during his hiatus, and his wealth of experience could prove to be vital for Leeds, during what will be a long and arduous campaign ahead.
The 30-year-old defensive midfielder would provide the Whites with a certain level of physicality that they are currently bereft of in the engine room.
The Congolese ace has been without a club since being released by Norwich City in the summer, but would be a useful option for Christiansen to consider.
Kris Commons in action
The talented attacking midfielder has been without a club since his release from Celtic in the summer, but the 34-year-old could make a real difference to Leeds' play in the final third.
The Scot possesses impeccable technique, and despite his advancing years, he still has a lot to offer at the highest level, and could prove to be a real asset for the Whites.
