Nigel Adkins says the Blades leave the January transfer window behind them with a 'positive mindset', despite admitting his frustrations at not being able to add the desired quality to his squad.
But, speaking prior to Saturday's Sky Bet League One encounter against promotion rivals Wigan Athletic at Bramall Lane, the Blades boss insists his existing players are in 'a good place' ahead of the final 18 games of the domestic campaign.
He remarked: "Prior to the window opening we monitored and tracked a few players and put money down on the table in a bid to secure them all permanently.
"Three were from a division above and that's because we only want to add players to the current group who can make an instant contribution, we weren't interested in adding major numbers because we are striving to clear a pathway for our own youngsters to progress.
"But, unfortunately, not because of a lack of endeavour, things didn't materialise as we had hoped. We had set our targets high, but in my opinion that's a good thing, we believed our targets were realistic and we had been following their progress for a number of weeks, although perhaps certain circumstances and changes went against us and by Monday teatime it became apparent that no matter what we bid, our offers were going to be knocked back."
The Gaffer added: "We could go two ways now, we could sit and moan and look to point the finger of blame or we can have a positive mindset and focus on the future, as we look to achieve promotion this season.
"Yes, we aren't in an ideal position, but there remains a possibility of success and from the players, to the fans, right through to the owners, it is in everyone's best interest that we win promotion now, this season.
"We will overcome our frustrations and if we are United together throughout the Club and strive to improve as we continually do then we can still achieve something we can all be proud of in the coming weeks and months."
