The Sky Blues claimed a memorable win over the Blades towards the back end of the 2021/22 season.
City had fallen behind midway through the first half after United midfielder, Sander Berge fired Paul Heckingbottom's side in front.
However, that lead didn't last long, as just a few minutes later, Viktor Gyokeres drew City level after latching onto a Michael Rose ball over the top.
In the second half, the Sky Blues blew the visitors away with three goals in 15 minutes.
Callum O'Hare struck a brace and then Matty Godden added another in the 68th minute, which wrapped up all three points at the Coventry Building Society Arena.
