With over 3,000 tickets already sold in advance and just over 2,000 available on the day, there is the possibility that there will be more away fans than home fans come 3 O'Clock in the afternoon.
There will be a pretty unusual sight at Gigg Lane, with Blades fans set to be situated behind BOTH GOALS and part of a side stand.
It is likely to be the Blades' biggest away following of the season, surpassing the 3,597 fans which travelled to Oldham on the first day.
Danny Wilson commented: "It will be a good occasion, we are taking plenty of fans and they will produce a tremendous atmosphere. We have been supported fantastically well this season and will need the backing of the fans on Saturday because it will be a tough test."
United will be looking to make it 11 wins out of their last 12 games at the weekend, and with neighbours Sheffield Wednesday facing table-toppers Charlton Athletic, the Blades are guaranteed to gain ground on the leaders, create a gap between third place, or even both if they were to do the business across The Pennines.
