Ajax have sacked their senior coaching team led by Marcel Keizer.
The Amsterdam club sit second in the Eredivisie table but announced in a statement on Thursday afternoon that manager Keizer plus his assistants - former Arsenal striker Dennis Bergkamp and Hennie Spijkerman - had been "removed from active duty".
Keizer took over in the summer from Peter Bosz, who moved to Borussia Dortmund but was sacked himself earlier this month.
Ajax chief executive Edwin van der Sar told the club's official website that he and Marc Overmars, the director of football, felt there was no option but to make a change.
