West Ham owners and the club board are meeting on Saturday to discuss Slaven Bilic's future as manager, according to Sky sources.
Co-owners David Sullivan and David Gold have a track record of standing by their managers, but Sky Sports News understand the club's hierarchy are "very worried" by what they saw during Friday's 3-0 home defeat to Brighton at the London Stadium.
Two goals from Glenn Murray and a Jose Izquierdo strike means the Hammers, who are 17th in the Premier League, have made their worst start to a season since 2010, taking just eight points from nine games.
Sky sources understand no final decision will be made on Bilic's future on Saturday as the owners ponder whether to sack him or give him two more games - at Tottenham in the League Cup on Wednesday, live on Sky Sports, and at Crystal Palace next Saturday.
Bilic's contract runs out at the end of the season, and Sullivan backed the Croatian ahead of Friday night's game admitting he felt it was "morally wrong" to sack managers and said he wants to give him opportunity to see out his three-year contract.
Speaking after Friday's defeat, Bilic said: "It is very hard for me to say anything clever in this moment apart from it's very disappointing.
"As manager I take full responsibility.
When asked if he was confident he will be given the opportunity to turn West Ham's form around, he said: "The board will do what they are going to do.
"It is their decision. We have been in this situation before and we got out. As a manager you take the credit and as a manager you take the full responsibility. I don't want to hide.
"I'm not worried [about the sack]. I'm doing my best."
