Chelsea have sacked manager Graham Potter after less than seven months in charge following Saturday's 2-0 home defeat by Aston Villa.
It was the Englishman's 11th defeat in 31 games since replacing Thomas Tuchel at Stamford Bridge on 8 September.
Chelsea have dropped to 11th in the Premier League - 12 points outside the top four - having spent more than £550m on new players this season.
The club's owners said they were "disappointed" to sack Potter.
Chelsea say Potter "has agreed to collaborate with the club to facilitate a smooth transition" and that Bruno Saltor will take charge of the team as interim head coach.
In a statement, co-controlling owners Todd Boehly and Behdad Eghbali said: "We have the highest degree of respect for Graham as a coach and as a person.
"He has always conducted himself with professionalism and integrity and we are all disappointed in this outcome."
Chelsea host Liverpool in the Premier League on Tuesday and face Real Madrid in the first leg of their Champions League quarter-final on 12 April.
There have now been 13 managerial changes in the Premier League this season, with Leicester sacking Brendan Rodgers earlier on Sunday.
'Along with our incredible fans, we will all be getting behind Bruno and the team as we focus on the rest of the season," the Chelsea owners added.
"We have 10 Premier League games remaining and a Champions League quarter-final ahead. We will put every effort and commitment into every one of those games so that we can end the season on a high."
Potter replaced Tuchel, who won three trophies in 20 months at Stamford Bridge, in September when the Blues were sixth in the top flight, following a summer during which they spent £255m on transfers.
Owner Boehly went on another remarkable spending spree in January, shelling out £288m.
Argentina midfielder Enzo Fernandez and Ukraine forward Mykhailo Mudryk were among eight mid-season signings - but the new additions have struggled to click on the pitch.
