West Brom have confirmed Sam Allardyce as the club's new head coach on an 18-month contract following the sacking of Slaven Bilic.
The 66-year-old will take training on Thursday ahead of the Premier League game against Aston Villa on Sunday evening.
West Brom sporting and technical Director Luke Dowling said on the West Brom website: "In Sam we have a man who has a proven Premier League pedigree with a track record of improving every club he has managed.
"We believe and, more importantly, Sam believes we have a group of players that have the quality needed to give the club its best chance of Premier League survival."
Allardyce, who left his last job at Everton two years ago, will bring his long-time assistant Sammy Lee with him to The Hawthorns.
He will take his first training session at the club on Thursday as his side prepares for Sunday's Premier League clash with Aston Villa.
Ironically Bilic was dismissed in the wake of what was arguably his side's most impressive result of the season so far, a 1-1 draw at Manchester City on Tuesday night.
