Marco Silva has been sacked by Everton.
The 42-year-old manager was let go earlier after talks between major shareholder Farhad Moshiri and the board of directors.
Wednesday's 5-2 defeat by Liverpool at Anfield was their ninth of the season and leaves them in the bottom three of the Premier League.
Former player and first-team coach Duncan Ferguson will take charge of the team for the game against Chelsea on Saturday.
Everton are now searching for their fourth permanent boss since Roberto Martinez was sacked in May 2016.
Former Everton manager David Moyes has been considered as a potential interim successor, but the suggestion has not been that well received by supporters.
Everton finished eighth in Silva's first campaign but, after spending more than £100m on players in the summer, they have won just four league games this season.
And they have some tough fixtures in the run up to Christmas with games against Chelsea, Manchester United, Arsenal and Manchester City.
