Rafael Benitez has been sacked as Everton manager after less than seven months in charge.
The Toffees appointed the former Liverpool manager, 61, as Carlo Ancelotti’s successor in June.
Everton, who lost 2-1 to Norwich City on Saturday, have won only one of their last 13 Premier League games and sit 16th in the table, six points above the relegation places.
The club say an update on a permanent replacement will be made in due course.
Former Everton striker Wayne Rooney, now manager at Derby County, has already been linked with the job.
Another potential candidate is Belgium coach Roberto Martinez. He was the first Everton manager sacked by owner Farhad Moshiri in 2016 but BBC Sport understands he still has admirers among the club’s hierarchy.
Everton held an emergency board meeting on Saturday to discuss Benitez’s future following the defeat at Carrow Road, which was a ninth loss in the club’s past 12 league games.
Everton’s travelling contingent demanded Benitez “get out of our club”, while a supporter invaded the pitch in an attempt to confront the Spaniard.
Benitez, whose previous job in the Premier League was at Newcastle United, leaves Everton with an overall win percentage of 31.8% – his lowest record in charge of an English club.
Everton have 19 points after 19 games and only twice previously have the Toffees had fewer points at this stage of a Premier League campaign (17 in 1997-98 and 2005-06).
