United's 1-0 defeat to Derby in January's Carling Cup semi-final first leg was the only blot on an undefeated copybook stretching all the way back to November.
It was a below-par display from the Reds against an inspired Rams side, although a 4-2 win in the second leg at Old Trafford secured United's safe passage to the final.
Neverthless United will be determined to avoid a repeat performance at Pride Park in this weekend's FA Cup tie with Nigel Clough's men.
Reds assistant manager Mick Phelan told ManUtd.com: "We went into that game with a few players who'd had a small break, and we didn't perform to our capabilities on the day. I think the result showed that – they deserved the victory.
"But it was one of those cup competitions where you get two bites of the cherry. In a one-off FA Cup tie we can't afford to play like that."
United are set to field a near full-strength side for Sunday's fifth-round clash, providing those players on international duty in midweek return unscathed, and Phelan is looking forward to the encounter.
"All being well, we'll have a full squad available this weekend," he added. "I expect it to be as passionate and hard a game as it was in January, but I think we'll be in a better frame of mind to play in this one."
