The Whites have added Middlesbrough winger Mustapha Carayol to their squad this month, whilst Liam Bridcutt's loan from Sunderland has been extended until the end of the season.
Manager Steve Evans will be looking to make some more additions, and it's suggested that he could make a second move for Charlton's Tony Watt.
22-year-old Watt, who made his name with Celtic, hit eight goals in 36 games for Charlton before joining Cardiff on loan in November, where he notched two goals in nine appearances.
The Yorkshire Evening Post report that Leeds had actually agreed to sign Watt in November, but Cardiff swooped in and took him to South Wales, only for a permanent deal to fall through.
As reported by Sky Sports, Cardiff have been placed under a transfer embargo, meaning their £1m move for Watt has fallen through, although they are able to extend his loan stay - leaving the door open for Leeds to finally try and bring him to Elland Road.
Would Watt be a good signing for Leeds?
For £1m, Leeds may not manage to find many better Championship forwards than Watt. He is still young, he has handled the pressure of playing for a huge club like Celtic, and he has impressed at this level before.
Watt became a firm fan favourite at Charlton for his impressive dribbling ability and hold-up play with the ball at his feet, whilst he also showed his quality with his exploits in front of goal at The Valley.
With strength, skill and pace, Watt can lead the line or feed off a target man like Chris Wood, who has been lacking a real partner during his time at Elland Road this term.
Boyhood Celtic fan Evans will have seen Watt burst onto the scene with the Bhoys in 2012, scoring what proved to be the winning goal in a Champions League tie against Barcelona - and whether it's a loan deal or a permanent move, Watt could be just what Leeds have been missing up front.
