Nigel Clough hopes that the disappointing performance at Crewe Alexandra last season will act as a motivational tool as the Blades head to the Alexandra Stadium on Saturday.
The Blades face Crewe with both sides in form, but Clough is hoping to draw on the memories of last season when United suffered a 3-0 defeat.
"We were rock bottom, everything had to change from then," said Clough of the defeat. "We don't want to go back to those times."
The defeat left the Blades in the relegation zone but it was the start of a tremendous run of clean sheets and an unbeaten 11-match spell.
"Most teams have the odd game when things don't go to plan and that was it, at Crewe last year," added Clough. "We got the lads together afterwards, put it behind us and moved on, three days later we beat Fulham in the FA Cup and things have progressed since then."
Clough, however, knows Crewe will be a tough test on Saturday, particularly as they have won their last three matches, against Coventry City, Walsall and Peterborough United.
"They have won three on the spin and should be held up as an example for Clubs with regards to sticking with your manager," added the United boss. "They have changed formation recently and are scrapping and fighting for each other. We catch them on a good spell but we have done well recently so it should be an interesting, and hopefully entertaining, game."
