Ajax have confirmed coach Martin Jol has left the club by mutual consent.
Jol, who only took charge of Ajax in May last year, claimed the expectations at the Amsterdam ArenA were too high. The club have announced on their official website that former Holland defender Frank de Boer will take temporary charge until the winter break.
Former Hamburg and Tottenham boss Jol told www.ajax.nl: "With pain in my heart I say goodbye to this wonderful club. We started something last summer that I would have finished. But I have come to realise that the expectations after last season were too high."
He added: "We cannot meet such expectations. The amount of criticism that the club has had to endure daily has led to unrest in the club and among players.
"I take this decision consciously before AC Milan v Ajax (in the Champions League) is played (on Wednesday).
"The coming weeks are very important and I sincerely hope that something happens in the squad to make it in the short term a winning team."
The Amsterdammers finished second in the league last term, a point behind FC Twente, scoring 106 goals and with a staggering goal difference of plus 86.
They have struggled to repeat their end-of-season form in the early part of this campaign and currently lie fourth, five points off leaders PSV Eindhoven.
