As yet, there is nothing concrete suggesting there is any truth in this – but there is also some genuine concern.
Respected journalist Alan Biggs, who has covered the club for many years, says on Twitter he’s “worried” and there is “unusual silence” from his sources on the subject.
More information should emerge on whether the rumours are true or not in the coming days.
From the outside, it is easy to see why Wilder’s position might be questioned.
The Blades have made the worst start in English top flight history and are currently bottom of the table with just two points from 17 games.
Many who don’t know the club would wonder why Wilder hadn’t already left or been sacked.
However, that fails to understand the truly remarkable job the 53-year-old has done since taking charge in 2016.
During his first four years in charge, Wilder took United from the bottom of League One to the Premier League. He ended a six-year stay in the third tier and took his boyhood side back to the top flight for the first time in more than a decade.
In 2019/20, with a squad largely made up of players who had featured in the Championship and League One, Wilder’s team finished ninth.
It is not hyperbole to say he may be the greatest manager in the club’s history.
Why Wilder could quit
There is little to no chance of the Blades boss being sacked, with both the owner and chairman having publicly backed him.
Now it seems that he could do that if the same hierarchy that have shown him a public show of support, don’t back him with the players he wants.
Wilder knows the only chance United have of achieving what seems impossible and avoiding relegation is by signing some quality.
He needs new players who can walk straight into and improve the starting XI.
Wilder wants a left-sided defender and a creative midfielder. Failure to deliver on that could see him quit – according to Yorkshire Live.
“There is no point bringing them in if they are not going to play,” said Wilder.
“From my point of view, I have passed the names on it’s now a level above me.
“They have to play and they have to be of a quality.
“New faces in the dressing room make a huge difference and that’s what I want to do.
“I want to bring in players who go straight into the team and play with that freedom and they have the opportunity to make the team perform better and galvanise those players around them.”
