Championship Bournemouth have sacked manager Jason Tindall, who was in charge for just six months.
The decision was taken after Tuesday's 2-1 home defeat by Sheffield Wednesday, with the team sixth in the table.
"We feel a change is needed now to give the club the best possible chance of achieving the goals clearly set out last summer," said a club statement.
Bournemouth, who were relegated from the Premier League last season, have lost four successive Championship matches and won just once in their past eight league games.
"Recent performances and results have fallen well below the board's expectations," the club said.
"We would like to place on record our thanks to Jason for his services to AFC Bournemouth over the past 22 years.
"He's someone who is fondly thought of throughout the club, having played an important role in rescuing it from its darkest days and taking it on the greatest journey it has ever had," the statement added.
