Danny Wilson is keeping a positive perspective on United's promotion prospects, despite admitting his frustration at the goal-less draw with Carlisle United on Easter Monday.
It is the third home game in succession that has ended 0-0 and Wilson feels his players are struggling to breakdown teams who come to Bramall Lane to defend.
The Gaffer commented: "It is obviously frustrating, but when you get the opportunities we got, especially given the way the opposition setup, then we should have capitalised.
"When you face a team who set out to frustrate you, it is crucial to make the most of the half-chances and we didn't do so again. If you breakdown the opposition the whole complexion of the game changes, but sadly we are finding it difficult to score at home.
"We have to do better, if it takes a scrappy 1-0 to win all three points then so be it."
Wilson felt the dismissal of Carlisle defender Sean O'Hanlon galvanised the Cumbrians rearguard and made it even harder for the Blades to find that elusive winner.
He continued: "The ten men got even tighter in the last 15 minutes, they didn't look to play out at all, they just cleared the ball and kept their shape.
"We didn't have that bit of luck in front of goal at times, but when the ball did bounce our way, we didn't take full advantage and that is the frustration.
"We remain in a strong position, though, and we must stay positive, why wouldn't we with the prize that remains within our sights?"
Looking ahead to Saturday's clash with play-off hopefuls Walsall, the Blades boss concluded: "It will be a tough game at Walsall on Saturday, especially with them having just put four goals past Coventry.
"It will be a really difficult match for us, but if we are at our best it is a game we are capable of winning.
"As we have been for several weeks now, barring the Stevenage blip, we don't give much away, but at the other end we must be more clinical."
