Matt Hill was keen to remain positive after Tuesday's 1-1 draw with Walsall.
United's experienced defender feels the Blades are progressing well under Nigel Clough, but admits it is a 'slowly but surely' progression.
He remarked: "It was a point in the right direction and we continue our unbeaten run, they are the two main positives.
"We controlled the game in parts and defended well, but one slip and we have conceded just after half-time again. We have to keep believing we will get out of trouble and are making positive small step forward.
"We are building confidence and the Gaffer wants us to be tough to best, first and foremost.
"Hopefully we can start to add that bit of quality going forward, but we have begun to lay some solid foundations."
On his recall to the starting line-up, in place of the suspended Harry Maguire, Hill added: "My strength is defending; I believe I am a good defender and I enjoying defending.
"As a centre-half all you have to worry about is defending, not getting forward and contributing down the flank. Defending constantly might sound tough but I relish the battle and challenge against a striker.
"I am a positive person, I have been in and out of the side for most of the season, but all I want to do is play regularly and impress the manager.
"We are all effectively on trial, the new manager has his own ideas and will want to integrate his own players into the team, but all I can do is try my best and give it my all as I always do."
