Leeds - Gary McAllister was fired by Leeds on Sunday after less than a year as manager.
The League One club said the former Scotland midfielder was "relieved" of his position following a recent poor run that has left them 15 points behind leader Leicester and five outside the playoff spots.
McAllister, who had a six-year spell as a player with the club, was hired in January after Dennis Wise joined Newcastle as executive director.
It is the latest setback for Leeds, which seven years ago reached the Champions League semi-finals and finished third in the Premier League in 2000.
Leeds said on its web site: "The decision was made to ensure that the new manager, when appointed, has the maximum number of games possible to move the club up the table. The transfer window opens in January and it will allow (the new manager) him to identify any new players he thinks can strengthen the current squad."
Leeds were relegated to the third tier of English football for the first time in their history in 2007.
McAllister's one job in management before Leeds at Coventry ended after just 18 months. He resigned in December 2003 to look after his wife, Denise, who was diagnosed with cancer. She died in March 2006.
