Sam Allardyce has agreed to become the new manager of West Brom, Football Insider understands.

This site revealed earlier today that Slaven Bilic has already been sacked by Albion’s Chinese owners and left the club.

A West Brom source has told Football Insider that Allardyce, 66, will be appointed Bilic’s replacement in a swift turnaround at the helm.

The former England manager has agreed the terms of a short-term deal that will initially only run until the end of the season.

It will be Allardyce’s first managerial post since he was dismissed by Everton in May 2018.

West Brom have decided to appoint the proven survival specialist now to give him time to use the January transfer window to strengthen the squad.

The Baggies hierarchy have noted how Allardyce kept Everton, Crystal Palace and Sunderland up in his previous three club posts after taking over midway through the season.

Albion have acted to give the experienced Premier League manager time to make his methods work.

They are also expected to present Allardyce with funds in January after Bilic spent £45million in the summer, mostly on loan signings already at the club.

West Brom have won just one of their opening 13 matches in the top flight since gaining promotion last season.

Bilic oversaw a spirited 1-1 draw at Manchester City on Tuesday night but that was not enough to keep him in the job less than 18 months after he took over from Darren Moore.

He steered the club to automatic Championship promotion at the first attempt but the club’s priority is staying in the top flight.

In other news, West Brom are working on £12m capture who could be Allardyce’s first signing.
