Lifelong supporter and former Blades player Wilder is regarded as one of the club’s greatest managers, having led them to promotion to the Championship in his first season in charge, 2016-17, and then into the Premier League two years later.
He took them to ninth in the top flight in their first season back, but left by mutual consent the following season, when they were bottom of the table.
After spells at Middlesbrough and Watford he returned for a second time to Bramall Lane in December 2023 following the sacking of Paul Heckingbottom, but could not prevent their relegation from the Premier League.
