Slaven Bilic has been sacked as manager of West Ham, with David Moyes set to be announced as his successor.
The club’s co-owners David Gold and David Sullivan decided to dispense with the Croatian’s services after Saturday’s 4-1 defeat at home to Liverpool.
It was West Ham’s sixth loss in 11 Premier League games this season and saw them drop into the relegation zone.
Bilic, who has been in charge of the Hammers for the past two-and-a-half years, was informed of his fate at a meeting on Monday morning.
West Ham confirmed the news just after 11am, with a statement reading: “West Ham United can confirm that Slaven Bilic has today left his position with the club.
“The chairmen and board of West Ham United would like to place on record their thanks and gratitude to Slaven and his team for their services over the past two-and-a-half years, but believe a change is now necessary in order for the club to move forward positively and in line with their ambition.
“West Ham United can confirm that Bilic’s coaching assistants Nikola Jurcevic, Edin Terzic, Julian Dicks and Miljenko Rak have also left the club with immediate effect.
“The club’s search for a new manager to take West Ham United forward is underway and an announcement regarding Bilic’s successor is expected to be made over the coming days.”
talkSPORT understands Moyes has already agreed to succeed Bilic.
The former Everton, Manchester United and Sunderland boss will sign a contract at the London Stadium until the end of the season.
Gold and Sullivan said the decision to axe Bilic had been made with “heavy hearts”.
The duo praised Bilic for his role in the move from Upton Park to the former Olympic Stadium, particularly the concluding win over Manchester United in the final home game of 2015-16 which helped to earn a seventh-placed finish in his first season as boss.
But recent results “have not been of the expected standard” and the Hammers hope a change in management can see the team climb into the top half of the table.
Gold and Sullivan added in a statement posted on whufc.com: “During the summer, the board invested heavily signing the players Slaven believed would complete the squad he needed to push the club back towards the level we had reached in his first season, and we believe we have the players capable of doing that.
“We have not seen enough indication of the required improvement to give us the encouragement that things would change and we would meet our Premier League aspirations this season.
“We believe a change is now necessary to ensure we can begin to move the team back in the right direction.
“We see this as an exciting opportunity to appoint a quality manager to the position to inject fresh ideas, organisation and enthusiasm into a very talented squad.”
