The Portuguese has overseen a period of steady decline since early September and falling into the relegation zone after a humiliating 5-2 defeat in the Merseyside derby at Anfield proved the final straw for majority shareholder Farhad Moshiri and the club’s board.
Duncan Ferguson has taken temporary charge of the Toffees and will oversee Saturday’s clash against Chelsea.
A statement from the club read: “Everton Football Club can confirm that manager Marco Silva has left the club.
“Majority shareholder Farhad Moshiri, chairman Bill Kenwright and the board of directors would like to thank Marco for his service over the last 18 months and wish him well for the future.
“Duncan Ferguson has taken temporary charge of the first team and will manage the side for the game against Chelsea on Saturday.
“The club aims to confirm a new permanent manager as swiftly as possible.”
Former manager David Moyes, potentially in association with ex-player Tim Cahill, is the front-runner for a permanent return to the club he left for Manchester United in 2013 but his name is not universally popular with fans.
Having finished last season – Silva’s first with the club – with a run of 17 points from a possible 24 and a summer spend of almost £120million, there was an expectation the team would kick on from their eighth-placed finish and challenge the established top six.
That did not materialised and while Silva has been unlucky with injuries, losing summer signing Jean-Philippe Gbamin after just two matches and then seeing midfielder Andre Gomes’ season ended by a dislocated ankle fracture, his team selections have been muddled and confusing.
In early December, he still did not know his best XI and scoring just 16 goals in 15 league matches point to an underlying problem which has not been addressed in the last three transfer windows, although much of the blame for failure in recruitment lies at the door of director of football Marcel Brands.
