Sam Allardyce has left his position as Everton boss, the club have announced.
The 63-year-old only joined the Merseysiders in November, replacing Ronald Koeman on a contract until 2019.
The Toffees were 13th in the Premier League at the time of his appointment and finished the season in eighth place.
But supporters were far from enamoured with the team’s style of play under the ex-England boss, and the atmosphere grew toxic at Goodison Park towards the end of the campaign.
His departure appeared inevitable after he blasted the club on Tuesday night for making sweeping boardroom changes without informing him.
And Allardyce was duly informed by Everton’s majority shareholder Farhad Moshiri on Wednesday morning that his contract would be terminated.
Professor Denise Barrett-Baxendale, the club’s new CEO, said: “On behalf of the Chairman, Board of Directors and Mr Moshiri, I’d like to thank Sam for the job he has done at Everton over the last seven months.
“Sam was brought in at a challenging time last season to provide us with some stability and we are grateful to him for doing that.
“However, we have made the decision that, as part of our longer-term plan, we will be appointing a new manager this summer and will be commencing this process immediately.
“Again, we’d like to place on record our sincere thanks to Sam for his work with us over the last few months and wish him well for the future.”
Former Watford boss Marco Silva is the frontrunner to replace Allardyce, although there are issues to overcome for them to appoint the 40-year-old.
Silva was Moshiri’s first choice to succeed Koeman, and Everton offered to pay a £12 million compensation fee to their Premier League rivals.
Watford refused to let Silva speak to the Merseysiders, and a drastic tailing off in form ensued – with the club winning just one of the next 11 games and Silva was subsequently sacked.
The two clubs remain in dispute over Everton’s approach for Silva, with Watford making an official complaint to the Premier League over the alleged tapping up and seeking a compensation fee.
