Everton have sacked former England manager Sam Allardyce less than six months after appointing him to get them out of trouble.
Despite the 63-year-old achieving his initial target of steering the English Premier League club away from any relegation fight early in his reign, the rest of the season has not gone so well.
He was an unpopular choice with supporters at the time and a growing section of the fanbase became increasingly opposed to him continuing in the role, leading to a toxic atmosphere at Goodison Park in the latter stages of the campaign.
Allardyce was not majority owner Farhad Moshiri's first choice, but he failed to lure Marco Silva from Watford, an approach which contributed to the Portuguese coach's sacking when results at Vicarage Road took a nose dive after the Toffees were turned down.
Silva is favourite to take over at Goodison.
"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 ..." said Denise Barrett-Baxendale, who was appointed the new chief executive on Wednesday in a boardroom reshuffle after Robert Elstone's departure.
"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."
Allardyce, who was briefly England manager in 2016 before returning to club management last season at Crystal Palace, had already reacted angrily to structural changes at the club before his meeting with the Iranian-born British tycoon Moshiri.
"I'm shocked, disappointed and disgusted that the football club didn't have the decency to tell me, my director of football and my staff about the changes," he told the Liverpool Post on Tuesday.
"They must have been in the pipeline for a considerable time but no one thought to tell me and my staff."
