Skysports.com understands Sheffield United are chasing defensive duo Alex Pearce and Dan Seaborne.
New Blades boss Micky Adams is in the market for defensive reinforcements with a new centre-back and left-back top of his wanted list.
Regular left-back Andy Taylor is facing a lenghty spell on the sidelines and Adams is keen to bring in a replacement in this month's transfer window
Adams is also keen to bring in a dominant central defender to help bolster his defence and he has Reading stopper Pearce and Southampton man Seaborne on his wanted list.
However, it remains to be seen if either Reading or Southampton would be willing to offload either player.
