The Blades boss has been in charge of the club since 2016 and overseen their incredible rise from League One to the Premier League.
Wilder’s tactics worked well as they finished position ninth last season.
However, this season has been a different story entirely, as they have managed just four wins from 28 games, scoring only 16 goals and conceding 45.
Speaking after last weekend’s 2-0 defeat at home to Southampton, Wilder made it clear he wanted greater backing from the board.
“There’s so many things we need to address,” he said.
“We need to keep our best players. There’s a couple who need to go. They have to go at the end of the season.
“I’d like to shake it up quicker. We looked like we’d run our race.”
Now the mutual decision has been taken for Wilder to leave Bramall Lane, with an announcement expected today, talkSPORT reports.
Sheffield United travel to Leicester this weekend – and it appears they’ll do so without Chris Wilder. The general consensus appears to be that an announcement will be made this afternoon.
Under-23s Coach Paul Heckingbottom is expected to be in the dugout at the King Power Stadium, with assistant Alan Knill also understood to have departed the club. The general consensus appears to be that an announcement will be made this afternoon.
