Former Blades striker Jack Lester is back with the club - heading up the famed SteelPhalt Academy, following recent changes to the management structure.
Sheffield-born Jack is the new academy manager and will be based at Shirecliffe.
He said: "I'm delighted to be back with the club, being a Sheffield lad and a former player, this club is close to my heart and is great to be able to take the reins and continue the excellent work that has gone on at the SteelPhalt Academy over the years.
"This academy has produced a tremendous amount of players who have gone on to represent the first team, play in the Premier League and play international football and it is the aim to continue this and to provide Chris Wilder and his coaching staff with young footballers who are worthy of pulling on the famous red and white shirt.
"With the assistance of the dedicated staff, I'm looking forward to getting to know everyone at Shirecliffe in coming weeks and months."
United chief Wilder added: "I am fully behind the decision and Jack's appointment is a positive move by the football club. It is important the club keeps moving forward and developing in every area and this is a step in the right direction."
Lester, 43, scored 16 times in 31 starts for the Blades in 2003 and 2004 but suffered with a serious injury. He has also represented Grimsby Town, Nottingham Forest and Chesterfield with distinction before moving into coaching.
He has worked in the academy systems at Notts County and Nottingham Forest and also managed Chesterfield, as well as working as assistant manager for the Welsh U21s squad.
As part of the academy management changes there has been a number of departures, including Travis Binnion.
Travis commented: "I would like to thank all my colleagues and young players, some of which I have worked with for a long time, for all of their support and hard work during my time with the club."
