Alvaro Arbeloa tweeted "better late than never" as the news broke that the struggling London club had made a decision to part ways with the manager who guided them to a seventh-placed finish two seasons ago.
West Ham have appointed David Moyes as their new manager.
"I'm looking forward to seeing them getting right behind the team and my team also".
The 54-year-old Moyes has taken charge of 499 games in the Premier League, most during a successful spell with Everton from 2002-13.
Arguably their biggest worry is that Moyes has signed on until the end of the 2018/2019 season.
In the face of potential fan disgruntlement at his appointment, Moyes pointedly targeted supporters in a video message that presented him as West Ham manager. "We are all here to do the job and get West Ham in the correct position and move up the table".
"You were talking about his experience, that's what we need". We need everybody with us.
After Moyes emerged as the leading contender to replace Bilic, many West Ham fans regarded his proposed arrival at the London Stadium with scepticism.
"I would like to welcome David to West Ham United", he told the Hammers' official website.
Moyes' first game in charge will be at Watford in the Premier League on 19 November. The team has been prone to collapsing after going behind it has already lost by at least a three-goal margin on four occasions this season and lacked any real identity under Bilic.
He added: "We've done a contract which suits both parties, we are all comfortable with it. Let's get the job done and then talk at the end of the year".
