Former Barnsley and Leeds United manager Paul Heckingbottom has been appointed as United's U23s lead coach.
The 43-year-old, who managed in the SPL with Hibernian last season, joins United with immediate effect.
Yorkshire-born Heckingbottom was an apprentice at Manchester United in the early 90s and enjoyed a 16-year playing career representing, amongst others, Scarborough, Darlington, Bradford City, Norwich City, Sheffield Wednesday, Barnsley and Mansfield Town before ending his playing days in non-league.
As a manager the former defender enjoyed success at Oakwell as caretaker manager following the departures of Danny Wilson and then Lee Johnson, before leading Barnsley to promotion to the Championship via the play-offs and a Football League Trophy triumph, both coming at Wembley. The journey continued in the second tier, as he led the Tykes to a respectable 14th place finish at the end of the 2016/17 campaign.
In February 2018, Heckingbottom moved to Elland Road following the departure of Thomas Christiansen and his first game was against the Blades at Bramall Lane.
Of Heckingbottom's appointment, Academy Manager Jack Lester remarked: "Paul is a fantastic coach and a great appointment for the club.
"He brings a wealth of experience to the Academy and we are delighted to have secured his services. We have some excellent prospects coming through in the next few years and it is vital we have top coaches, like Paul, and Derek Geary, who remains lead coach for the U18s, to develop them."
