David Wetherall is to leave Bradford City, ending his 12-year association with the club.
The 40-year-old, currently the Bantams' youth team manager, will join the Football League next month as their head of youth development.
He told the club website: "It has been an extremely tough decision to leave a club I have such an affinity with.
"I just felt that the opportunity was too good to turn down and I will leave here with many special memories."
Wetherall joined Bradford from local rivals Leeds United in 1999 for £1.4m, a club record transfer fee for the Bantams at the time.
As a defender he famously scored the goal against Liverpool on the final day of the campaign that kept Bradford up in their debut season in the Premier League.
City were relegated the following season, and Wetherall went on the represent the club in every division as the club's slide down the league continued.
He had two caretaker spells in charge of the club, in 2003 and 2007.
Wetherall played his final game for the club at the end of the 2007/8 season before joining the club's coaching staff under then-manager Stuart McCall.
