David Moyes is set to be unveiled as the new West Ham manager, Sky Sports News understands.
The former Manchester United, Everton and Sunderland boss will succeed Slaven Bilic on a six-month contract after the Croatian was relieved of his duties on Monday.
Live Nissan Super Sunday
As the 16th manager in the Hammers' history, Moyes will be charged with keeping the club in the Premier League. They are currently languishing in 18th place with just two wins from 11 games.
His first match in charge will be the Super Sunday clash against Watford at Vicarage Road on November 19, live on Sky Sports Main Event HD and Sky Sports Premier League HD.
Prior to Bilic's sacking, Moyes publicly expressed an interest in the West Ham job while working as a TV pundit in Doha.
The 54-year-old told beIN Sports: "I've always said I want to go back into club management and if the right opportunity comes around, then I'll be interested.
"I've been there myself, I know what Slaven is going through at the moment. He must be hating it and wanting to get a result as quickly as he can. If it becomes available yes, but at the moment it's not available."
Moyes has been out of working since leaving Sunderland at the end of last season, having failed to keep them in the Premier League. Sunderland won just six of their 38 top-flight matches under Moyes and finished bottom of the table.
West Ham were thrashed 4-1 at home by Liverpool on Saturday and Bilic was fired less than 24 hours after his side fell into the Premier League's bottom three thanks to Everton's 3-2 win over Watford.

Speaking on his way out of the club's Rush Green training base, Bilic said: "I am sad and disappointed but not in the club, I expected it to be fair.
"There are no hard feelings. I am going to be, especially when some time goes by, very proud of my work here."
Moyes will face a tough run of fixtures in the lead up to Christmas, with matches against Manchester City, Chelsea and Arsenal still to come.
