Coventry City sacked their manager Roland Nilsson and assistant Jim Smith today.
Chairman Mike McGinnity said: "We understand the fans' frustration completely in addition to the need for immediate change.
"The board has therefore decided to terminate the contracts of Roland Nilsson and Jim Smith with immediate effect".
The club said McGinnity and chief executive Graham Hover "expressed the view in a meeting with Nilsson this afternoon that the club's first division performances this season have been totally unacceptable.
"They also conceded that the Sky Blues' failure to achieve a play-off position, after losing 19 games and drawing six this campaign, is not good enough," the club said.
Reserve team manager Trevor Peake and goalkeeping coach Steve Ogrizovic will take charge of the team for the final fixture of the season away at Burnley on Sunday.
Nilsson had been in charge at Coventry, who were relegated from the Premiership last season, since September when he replaced Gordon Strachan. Coventry are 11th in the first division standings.
