Executive members and season ticket holders have until 08:00 tomorrow to apply for tickets to see United take on Aston Villa at Villa Park on February 10.
United have got approximately 2,315 tickets priced at £43 for adults, £30 for over 65s and £24 for under 16s.
On January 6, we predicted United would get 2,347 tickets for this game and got the prices spot on.
Last season, reds paid £35 for adults and £21 for over 65s and under 16s and the allocation was 2,800.
Liverpool got the same number last season and had it reduced by about 500 this season due, Aston Villa said "to persistent standing" in the Liverpool end.
Aston Villa have not yet responded to our request for them to clarify the reason for the reduction.
Apply online or by calling 0161 868 8000. Ballot results are expected to be out on January 27.
