Nigel Clough is optimistic about extending Conor Coady's loan spell with the Blades until the end of the season, after expressing his delight at recruiting Bob Harris on a permanent basis.
Coady's youth loan expires when the Liverpool midfielder turns 21 later this month and Clough, who was pleased with his January dealings, says an extension rests with his parent club.
The Gaffer remarked: "Conor (Coady) is a loan we will look at extending later this month, apart from Saturday he has improved with every game and done very well. Obviously we are keen to keep him around, but Liverpool will have the final say on his future.
"We are pleased that we have managed to get Bob on a deal until the end of the season and Billy (Paynter) is now just about up to speed in terms of match fitness and sharpness, whilst Stefan (Scougall) and John (Brayford) have impressed since arriving at the club."
The Blades boss, though, is cautious that certain targets might be put off by the current position in the League One relegation zone, adding: "We are continuing to make inquiries ahead of the loan window reopening, but obviously our league position can have a detrimental effect.
"It happened with Alan Judge, who chose Brentford over us, and given where we are and where they are you can't blame him."
