Ajax have suspended boss Marcel Keizer and coaches Hennie Spijkerman and Dennis Bergkamp from active duty.
The four-time European champions appointed head coach Keizer as a replacement for Peter Bosz in June, agreeing terms on a two-year deal with an option for one additional season.
But that contract looks set to be ripped up just six months in after it was confirmed on Thursday that the club had, for the time being at least, relieved Keizer, his assistant Spijkerman and club legend Bergkamp of their roles.
Michael Reiziger and Winston Bogarde, previously respective head and assistant coaches of the club's youth side, will take temporary charge ahead of Sunday's home meeting with Willem II.
