The Blades started their FA Youth Cup trail in the third round; winning 4-1 away at Cheltenham Town before defeating Millwall (3-0) at the Lane.
In late January United completed a 3-1 victory over Blackpool; youngster Jordan Slew netting a brace in extra-time to see off the Seasiders.
United will be keen to land Middlesbrough in the two-legged semi-finals should they progress in the Midlands. The academy side beat Boro 4-1 on 12th February – Matt Harriott (brace), Jordan Slew and Callum McFadzean all scored for John Pemberton’s side.
They are likely to start with a forward line starting with England U-19 international Slew and Joe Ironside, the pair have progressed well in the reserves. George Long may start in goal whilst Spaniard Carlos Pomares, Ben Montgomery and Matt Harriott and Harry Maguire all continue in defence.
Leicester City also started their cup campaign in round three; they saw off Hartlepool United in a 2-1 home win before defeating Blackburn Rovers (3-1) at the Walkers Stadium in the fourth.
The Foxes made it a hat-trick of home victories when they saw off Preston North End (4-3) in a seven goal thriller over a week ago at the Walkers Stadium.
Expected Eleven: Long, Montgomery, Pomares, Harriott, Maguire, Kennedy, Gregory, Whitehouse, Slew, Ironside, McFadzean.
We wish our youngsters all the very best at the Walkers Stadium and that they come away with a victory – we know it will be a tough encounter.
