West Ham potential Moyes began to come to prominence when he was in charge of Everton, leading him to get the top job at Manchester United after being identified by Sir Alex Ferguson as the ideal replacement, which ended badly before he moved to failed roles at Real Sociedad and Sunderland.
He was sacked by Manchester United after just ten months, suffered the same fate after a year at Real Socidead and left his most recent job at Sunderland after a single season following their relegation to the Championship.
Co-chairmen David Gold and David Sullivan have a track record of mostly standing by their managers, and Sullivan said last month he wanted to honor Bilic's contract, which was due to expire at the end of the season, "unless things are desperate".
West Ham is in third-to-last place in the Premier League after 11 games.

"I hope West Ham fans are going to see a team that is organised and disciplined", Moyes said. "We need their support".
"It wouldn't be a lot, let's face it we believed at the beginning of the season that we had the best squad of players for a decade". He will be telling us what he thinks we need. So I'm hungry to make sure I get things right now.
To no one's surprise, David Moyes was announced as the new West Ham manager early on Tuesday morning.
The good news for David Moyes is that he has just under two weeks to prepare for his first game, at Watford after the global break.
The idea that West Ham have been approaching the big names in football management suggests Bilic had been on borrowed time for some while, however, he was shown the exit after their embarrassing 4-1 defeat at home to Liverpool on Saturday evening.
