Micky Adams has resigned as manager of Port Vale in the wake of a six-match losing sequence for the League One side.
The 52-year-old former Fulham, Sheffield United, Brighton, Leicester City and Coventry City boss had been in charge at Vale Park since May 2011.
He guided the club to promotion from League Two in the 2012/13 season but has decided to resign following extensive talks with chairman Norman Smurthwaite.
This has not been an easy decision to make, which has been made even more difficult by the strong relationships I have forged during my time at the club.Micky Adams
Adams said: "It is with great sadness that I have decided to leave Port Vale but I believe I am leaving the club in a stronger position than when I joined.
"Although the role of a football manager brings with it a roller-coaster of emotions, I will never forget my time at Vale and the many happy memories I will take away with me.
"This has not been an easy decision to make, which has been made even more difficult by the strong relationships I have forged during my time at the club. I would like to thank my immediate team, all of the staff at Vale Park and the many players I have worked with throughout my two spells. I have met some truly fantastic people."
Port Vale, 1/1 to be promoted from League One this season and 1/1 to be relegated, can be backed at 1/1 to beat Barnsley on Saturday.
