Everton have sacked manager Ronald Koeman after Sunday’s 5-2 home defeat by Arsenal left them in the Premier League relegation zone.
A statement said the club “would like to express their gratitude to Ronald for the service he has given to the club over the past 16 months”.
The Toffees are 18th in the Premier League and have won just two of their nine league games this season.

“I still believe I can change the whole situation,” Koeman had said on Sunday.
Koeman became the third Premier League managerial casualty of the season after Frank de Boer left Crystal Palace and Craig Shakespeare was sacked by Leicester.
The 54-year-old Dutchman, who guided Everton to seventh place in his first season in charge last term, paid the price for a poor start to this season despite having spent £140m in the summer.
Everton owner Farhad Moshiri gave Koeman his backing a fortnight ago after their 1-0 defeat by Burnley, but the Toffees then drew at Brighton and lost to Lyon, in the Europa League, before their Goodison Park humbling by Arsenal.
Everton’s chances of progressing from Europa League Group E are slim, with the Merseysiders bottom after defeats by Atalanta and Lyon and a draw with Apollon Limassol.
‘Something has to change quickly at Everton’
Former Leicester City striker Steve Claridge, speaking on BBC Radio 5 live after Everton’s loss on Sunday, said “something has to change quickly” at Everton.
“On this evidence, Everton are in real, real trouble,” he said.
“There were very few redeeming features about their play. There is no belief in what they are doing and they are not good enough to play like that.
“There is no reaction to what is going on. The fans have just given up reacting. Apathy is too strong a word but they look like they’ve had the guts knocked out of them.”
