Thomas Christiansen has been sacked as Leeds head coach after a recent dip in form for the Championship club.
Christiansen, who took the job last summer, has paid the price for the slump which culminated in Saturday's 4-1 home Championship defeat to Cardiff.
The Whites have failed to win since their 2-1 St Stephen's Day victory at Burton, a run which has seen them fall out of the running for the play-offs and also be knocked out of the FA Cup by League Two Newport.
Christiansen, 44, was an unknown choice when Leeds decided he was the man to replace Garry Monk last summer.
Monk turned down a role under the club's new owner, Andrea Radrizzani, opting to take on a new opportunity at Middlesbrough which ended with the sack in December.
Christiansen, a former Barcelona and Spain striker of Danish descent, made his name in Cyprus and seemed to immediately settle in England, with Leeds topping the table in early September.
However a run of one win in eight put the skids on their promotion charge and, although they recovered in November and December, their current seven-game winless run has seen Radrizzani pull the trigger.
"Leeds United can confirm that head coach Thomas Christiansen has left the club," a statement read.
"Chairman Andrea Radrizzani and the board of directors would like to thank Thomas and his staff for their hard work over the past eight months."
Christiansen's departure means Leeds are looking for what will be a 10th manager since the sacking of Simon Grayson six years ago.
Grayson himself will join the list of potential candidates, as will Steve McClaren, who was in attendance as Leeds were soundly beaten by Cardiff.
Christiansen won 15 of his 35 games in charge of Leeds.
