The Sky Blues, who have not won their last three league matches, are reportedly lining up a loan move for Barnsley striker Chris Dagnall.
Pressley has admitted that the side's recent form has heightened the need to bring in new faces.
"I might need to bring in a few players to freshen the group up. We have been working hard to try and do that," he told BBC Coventry & Warwickshire.
"These players have done extremely well thus far, but we need to look at bringing some bodies in to give the squad a boost and give us a hand.
"It looks like the last few games have caught up with them."
Coventry currently sit 13th in League One.
