Tottenham have announced head coach Juande Ramos and sporting director Damien Comolli have left the club as part of a mass exodus of backroom staff.
Ramos had led Spurs to their worst ever start to a league season, and first-team coaches Marcos Alvarez and Gus Poyet have also left the club as they seek a transformation in fortunes.
Development squad coach Clive Allen and youth team manager Alex Inglethorpe will take charge of the squad for Sunday's Barclays Premier League clash with Bolton at White Hart Lane.
Ramos came under huge pressure after Spurs claimed just two points from their opening eight league games, leaving them four points adrift at the bottom of the table.
Their UEFA Cup group campaign also got off to a poor start on Thursday when they slipped to an unconvincing 2-0 defeat at Udinese.
And after David Bentley and Jonathan Woodgate went public in their criticism of the team's displays earlier this week, chairman Daniel Levy appears to have lost patience with Ramos's faltering regime.
A statement released by the north London club on Saturday evening read: "The club can announce that Damien Comolli, sporting director, Juande Ramos, head coach and first-team coaches, Marcos Alvarez and Gus Poyet, have left the club, with immediate effect. We wish them well.
"Clive Allen, development squad coach, and Alex Inglethorpe, youth team manager, will take charge for Sunday's league match against Bolton.
"An announcement will be made on first-team coaching staff in due course."
