OLE Gunnar Solskjaer has stepped down at Cardiff City after less than nine months in charge.
The Bluebirds are 17th in the Championship after three losses in seven games and due to face Derby County at the iPro Stadium on Saturday.
Veteran defender Danny Gabbidon and Scott Young are in temporary charge.
Solskjaer succeeded Malky Mackay on 2 January, 2014.
In a statement Cardiff chairman Mehmet Dalman said: "Due to a difference in philosophy of approach to the game, we have decided to part company amicably."
Owner Vincent Tan said: "Ole was hired by Cardiff City on our understanding and belief that he would help us fight relegation from the Barclays Premier League.
"Unfortunately that did not happen. After the club was relegated many people advised me to let him go, but I decided to keep Ole on for the Championship season.
"Regrettably our recent results do not justify Ole's continued role as manager at Cardiff.
"Ole has therefore decided to step down and I have accepted this.
"During my short association with Ole, I have found him to be an honest and hardworking professional, but unfortunately the football results were not in his favour."
