Danny Wilson is backing Jonathan Forte and Barry Robson to play an instrumental part in the Blades promotion push.
The duo, signed on transfer deadline day, impressed as second half substitutes in Friday's defeat to Coventry and Wilson believes both will be instrumental between now and the end of the season.
Speaking of the contribution of his aforementioned recruits against the Sky Blues, Wilson commented: "Jonathan (Forte) made a real impact from the moment he was introduced.
"Supporters will have noticed he has changed since the last time he played for the Blades and that comes through experience.
"He gives us exactly what we need, a threat in behind, genuine pace and his movement makes life tough for the opposition.
"Barry (Robson) is an old head and on the ball has real class. The fact he hasn't played for three months means we have to use him carefully initially to avoid him picking up a knock.
"His first touch was the pinpoint corner for the equaliser, so again he has plenty to offer us and gives us something a bit different to what we already have.
"Hopefully with Barry we can get him up to full speed within a week or two."
When questioned about his plans to enter the loan market when it re-opens later this week, Wilson added:
"If someone becomes available and we feel he would add something to the squad then we would look to bring him in, but at the moment that isn't the case.
"We have to know what is available to us elsewhere and if we can improve the squad then obviously we would look to do so."
