Blackburn Rovers have sacked manager Henning Berg after just 57 days in charge at Ewood Park.
The 43-year-old former Rovers defender replaced Steve Kean on October 31 but the club have won just one of their 10 matches since his appointment, reports the BBC.
The Norwegian's final game was a 1-0 defeat at Middlesbrough on Boxing Day, Blackburn's fifth loss in six outings.
The club are already talking to potential replacements and hope to make an announcement shortly.
Assistant manager Eric Black, coach Iain Brunskill and goalkeeping coach Bobby Mimms have also left Rovers, who are 17th in the Championship.
Berg, who won the Premier League title as a player with Blackburn in 1995, signed a three-year deal at Ewood Park.
His only previous managerial experience had been in his home country with Lyn Oslo and Lillestrom.
Kean's resignation at the end of September had followed months of protests from supporters aimed at the Scot and owners Venky's.
Despite the off-field turmoil, Rovers had started well in the second tier after suffering relegation from the Premier League in May - they were top of the table prior to Kean's final game in charge.
But Blackburn have struggled for points since Berg's arrival and have dropped into the bottom eight as a result of their poor form.
He failed to win a home match in his short stint at the helm, with a 4-1 victory at struggling Peterborough on 17 November their only success during Berg's reign.
A statement on Blackburn's official website said: "Blackburn Rovers has announced the departure of manager Henning Berg, assistant manager Eric Black, first-team coach Iain Brunskill and goalkeeping coach Bobby Mimms with immediate effect.
"This decision has been taken following a very disappointing sequence of results.
"The club thanks the four men for their efforts and wishes them every success for the future."
Blackburn travel to Barnsley on Saturday.
