United's rewards for edging past Hartlepool on penalties in midweek is a trip to Merseyside to face David Moyes's men.
The draw, which was made by Trevor Francis and Lawrie Sanchez last night, saw United being paired against a team who has Bramall Lane legend Phil Jagielka in their ranks.
United were an unseeded team in the draw, and were strangely already down to play away from home.

However, season ticket holders are able to gain a 20% discount on prices, with tickets priced £13 Adults, £10 Seniors and £6.50 Juniors.
