Kieffer Moore celebrates after scoring Wrexham's fourth goal in the clash with the Blades.
The Welsh international bagged a double as Wrexham produced a remarkable comeback from 3-1 down to defeat his old team Chris Wilder's men in a pulsating 5-3 Championship contest.
Patrick Bamford's sweetly-struck volley put United ahead, but the hosts equalised almost immediately thanks to a Tyler Bindon own goal.
A quickfire double from Bamford and a close-range header seemingly have handed United in command at 3-1, until the towering striker reduced the arrears with a thumping header of his own.
The winger's glancing effort early in the second half brought the scores level, paving the way for Moore to put Wrexham ahead for the first time with a quarter of an hour remaining.
Josh Windass' confident penalty in the closing stages sealed the win, ending a run of five games without a win for the Welsh club.
In their previous meeting in the FA Cup back in 2023, it ended in a epic six-goal stalemate.
This latest clash delivered another high-octane, dramatic installment in their recent history.
With the support of Hollywood owners, the club's meteoric rise through the leagues has brought them back to the Championship for the first time since the 1980s.
Coming into this fixture on the following a winless run, manager Phil Parkinson had called for a replication of the famous spirit from those past encounters.
The players certainly responded, overcoming a 3-1 deficit to claim a memorable comeback win that underscores their never-say-die character.
