Notts County boss Steve Cotterill is to leave the club when his contract ends on 30 May after failing to commit his future to the League Two champions, reports BBC Sport.
The 45-year-old is now being linked to managerless Portsmouth, having turned down an offer from Coventry.
Magpies chairman Ray Trew said: "The job that Steve did for us here will live long in the memory of all Notts County fans and, as is a mark of all great managers, he leaves the club in a much better position than when he arrived.
"To his credit, Steve is a very ambitious manager and he feels that the time is right to take stock of his current situation before deciding upon his next career move, which I completely understand.
"Steve leaves Meadow Lane with my thanks and appreciation and in the hope that he may one day return to the club to manage us at the very highest level."
Cotterill joined County on a short-term contract in February and in April his side clinched promotion to League One.
He stated: "It has been a real pleasure working with such a fantastic group of people from the chairman and chief executive, players, the backroom staff, office workers and ground staff.
"The fans have been magnificent to me and I would like to thank everyone connected with the club for how they have received me since I've been here and wish them all the very best in the future.”
