Manager Mark Wright and his assistant Dave Moss have left League Two newcomers Chester City - just a day before the start of the new season.
Wright had been in charge of Chester for two-and-a-half years
The former England international defender confirmed his departure, but would not make any further comment.
Wright, who has also managed Oxford, took over at City in January 2002 and led them to promotion from the Conference last season.
Ex-Tranmere manager Ray Mathias has been placed in caretaker charge.
Moss, a former Macclesfield boss, only took over as Wright's assistant at the end of May.
Chester begin their League Two campaign at Notts County on Saturday.
