United coach Erik Ten Hag picked a completely different starting eleven from the ones that defeated Arsenal a few days before, as the team was stacked with teenagers.
Nathan Bishop, the United goalkeeper, was awarded a yellow card for an unlawful challenge on Wrexham player Paul Mullin, who had to be replaced as a result of the incident.
On the other hand, Lee's goal gave Wrexham the lead in the encounter in the 29th minute, giving the Welsh team the advantage.
Less than 7 minutes after the opening goal, Hayden rose highest to head the ball into the nett following a long throw-in that a young United defender headed into the far post.
In the sixth minute of first-period stoppage time, United cut the deficit in half thanks to a goal from 19-year-old Jurado, who was assisted by Alvaro Fernandez.
In order to have a fresh team during the second half, Wrexham manager Phil Parkinson made 10 substitutions.
United youngster Daniel Gore was sent off in the 47th minute of the encounter, leaving the English team with 10 men early in the second half.
The clubs fought hard in the second quarter, with United looking to equalize and restore parity and Wrexham looking to extend their advantage.
However, Dalby restored Wrexham's two-goal lead in the 69th minute, making the score 3-1. Parkinson's team performed well to hang on to the advantage and see the game through to secure a major win for the lowly side.">
