Michael Doyle felt the Blades were good value for the 3-1 victory at Carlisle United on Saturday, but he is urging his team-mates to become more 'ruthless'.
Goals from Ryan Flynn and Nick Blackman gave the Blades a two-goal cushion at the break, but United weren't as dominant after half time and subsequently Danny Livesey netted to give the hosts hope before the Blades added a third goal in the closing stages.
On the three points, the skipper commented: "The frustrating thing was that everything we did so well to begin with, we didn't do after the re-start. It was almost like we thought 'let's have a look at what Carlisle can do' and that gave them a lift.
"I don't think any of the lads were happy with how difficult we ended up making it for ourselves and we've got to get more ruthless.
"At the end of the day, though, this was a really good result because Carlisle is always such a difficult place for anyone to come. It doesn't matter who or where you are, you always know that you're going to have to work for a result at Brunton Park."
Neill Collins was credited with United's decisive third, but the skipper is adamant the ball was already over the line when Collins intervened.
Doyle concluded: "We've looked back on the video with the analyst and the ball was definitely over the line when Neill got at it.
"If it wasn't then I'd gladly let him have it but it was and I'm claiming that one... 100 per cent!
"The most important thing was that it made sure of the result for us. It wasn't the prettiest of goals you'll see but they all count."
