Steve Davis is Crewe's new manager after Dario Gradi handed over responsibility for first-team duties.
A statement on the club's official website highlighted the new Football League rules governing youth development as the reason behind the decision, with Gradi set to continue his role behind the scenes as director of football at Gresty Road after 1,353 games in charge.
Gradi boasts an association with Crewe spanning three decades, having initially managed the club from 1983 until 2007, before returning to the hotseat for lengthy spells - officially as caretaker manager - following the dismissals of Steve Holland and Gudjon Thordarson in 2008 and 2009 respectively. The Railwaymen currently lie 18th in League Two.
