Holloway knows all about winning at Old Trafford - he did it as a player with QPR.
He insisted: "It just sums everything up about our overall story that we have to go to the home of the champions and win, and, for me, that's better than having to do it at somewhere like Wigan.
"I'd rather have this scenario, no matter how good United are, because it's the ultimate place to go and I want my lads to savour the moment. It's just wonderful, absolutely wonderful.
"I've been there as a player and won 4-1 (with Queens Park Rangers in 1992). We were 2-0 up before I'd had a touch. Dennis Bailey was on fire and finished with a hat-trick. We may need something similar but the main thing is, I want my lads to try and perform in front of an immense crowd."
