Sheffield United manager Kevin Blackwell has not ruled out the possibility of Kyle Naughton returning to Bramall Lane this month.
The 21-year-old moved to Tottenham Hotspur last August as part of the £10million deal that saw Kyle Walker move from United to Bramall Lane.
Walker has since returned to the Blades on loan while Naughton has made just three appearances for Harry Redknapp's side this term, with his only start coming in the Carling Cup win at Doncaster Rovers.
Blackwell told the Sheffield Star: "We're always interested in signing good players and Kyle Naughton's certainly one of those.
"But any decision about his future will be taken by Harry Redknapp and Spurs chairman Daniel Levy.
"I talk to Harry a lot because he likes to know how Kyle Walker's getting on and I'm interested in how Kyle Naughton is doing because he's one of us. We're two teams with obvious associations and who get on together well."
