Sam Allardyce will finalise terms on a deal to become Everton manager on Wednesday, the Premier League club have confirmed.
The Toffees sacked Ronald Koeman on October 23, with the Dutchman presiding over a woeful start to the season that saw them claim just two wins in their first nine Premier League matches.
The club are 17th in the Premier League – a place above West Ham – and have lost five times under Unsworth, with a 4-1 defeat at Southampton on Sunday coming on the back of a 5-1 Europa League thrashing at home to Atalanta.
"Sam Allardyce will be at USM Finch Farm [Everton's training ground] this afternoon to finalise terms on becoming the new manager of Everton Football Club," the club tweeted.
"David Unsworth will remain in charge of the Blues for tonight's Premier League match against West Ham United at Goodison Park."
Watford boss Marco Silva emerged as Everton's top target in the aftermath of Allardyce's initial rebuttle, while Burnley's Sean Dyche and Shakhtar Donetsk head coach Paulo Fonseca were also linked.
However, the Hornets played hardball over Silva, while the Dyche rumours failed to come to fruition and Everton struggled with Unsworth at the helm – his only win so far coincidentally coming courtesy of a 3-2 comeback triumph over Watford.
After leaving Palace, the 63-year-old Allardyce stated that he would only consider an international job, but the Everton post has proved too good to turn down.
