Chelsea have sacked head coach Liam Rosenior after less than four months in charge and on the back of losing five consecutive Premier League matches without scoring for the first time since 1912.
Rosenior arrived at Stamford Bridge in January, signing a five-and-a-half-year deal, but has won just 11 of his 23 games across all competitions.
After Tuesday's 3-0 defeat at Brighton, Rosenior said the performance was "indefensible" and "unacceptable" as he faced angry chants from the travelling supporters.
They subsequently slipped to seventh in the Premier League standings in a further blow to their hopes of qualifying for next season's Champions League.
"Liam has always conducted himself with the highest integrity and professionalism following his appointment midway through the season," Chelsea said.
"This has not been a decision the club has taken lightly, however recent results and performances have fallen below the necessary standards with still so much more to play for this season."
Calum McFarlane will take over as interim manager until the season of the season.
McFarlane, who was Rosenior's assistant, was in charge for a 1-1 draw against Manchester City and a defeat at Fulham in January after previous boss Enzo Maresca was sacked.
"As the club works to bring stability to the head coach position, we will undertake a process of self-reflection to make the right long-term appointment," Chelsea added.
