Back in November 2015 while he was in charge of Northampton Town, Wilder spoke his mindÂ in a post-match interview that will live long in the memory.
Following a 2-1 win over League Two rivals Notts County, the then-Cobblers boss didn't hold back when journalists asked him about off-pitch problems as the clubÂ wasÂ in desperate need of a takeover to save it from extinction.
In an incredible ten minute rant, Wilder pleaded with then-chairman David Cordoza to agree a takeover deal as Northampton faced a winding up order for an unpaid tax bill of Â£166,000.
Just the season beforeÂ Wilder and co. had escaped loomingÂ relegation and,Â despite staff not being paid, made it to mid-table safety in League Two.
Following his impassioned speech, the 51-year-old went on to work a miracle that Blades fans will know well, as he led Northampton to 99 points andÂ the League Two title.
At the end of the 2015/16 season, Wilder joined his beloved United but didn't stop wearing his heart on his sleeve, as anyone that remembers his well documented rant about Norwich City in September 2017 can testify.
