Yes he did. Wanted more money after keeping them up, didn't get it and left.
They decided not to renew his contract. He didn't walk out.
They had his replacement Jan Poortvliet lined up before he went.
This is what their chairman said at the time:
"the board have been looking closely at the situation on the playing side of the club whereby we are inevitably going to have to depend to a large extent on the quality of our youngsters in the academy and the reserve team.
Our view on that was we would need to adopt a European-style coaching system comprising head coach, with the objective of linking the academy to the first team.
The board believe this will create opportunities for our younger players, which might not occur within the traditional English management structure."
