Leeds have sacked Paul Heckingbottom from his position as head coach, with Mick McCarthy and Marcelo Bielsa among those being linked to the vacant post.
Former Barnsley boss Heckingbottom replaced Thomas Christiansen at the start of February, but lost eight of his 16 matches in charge as Leeds finished 13th in the Sky Bet Championship.
Managing director Angus Kinnear said in a statement: "On behalf of the board of directors at Leeds United I would like to thank Paul for the commitment and passion he has demonstrated since he joined the club earlier this year.
"Paul came to us during a difficult period in the season and has conducted himself in an exemplary manner despite results not going as any of us had hoped."
Assistant manager Jamie Clapham, head of fitness Nathan Winder and analyst Alex Bailey will also leave the club, with set-piece coach Gianni Vio not having his contract renewed.
Kinnear added: "Our objective is to bring in a head coach with more experience who can help us reach the goals we have talked about since we became custodians of the club last summer.
"We are confident of making a quick appointment and we thank our fans for their continued support."
