Alan Pardew has been appointed as West Brom's new head coach, the club have announced.
The former Newcastle manager has agreed a two-and-a-half year deal to replace the sacked Tony Pulis.
Pardew has been out of work since last December when he was axed by Crystal Palace - the team he will face in his first game in charge of the Baggies on Saturday.
Pardew told the club's official site: "I'm thrilled with the opportunity Albion have provided and looking forward to getting to work with what I consider to be a talented group of players.
"The immediate challenge will be to get the results we need to pull ourselves up the table. But I'm aware that while I'm joining one of the great, traditional clubs of English football, it is one determined to go forward in the Premier League.
"It's an exciting opportunity to play a part in that ambition."
The 56-year-old had widely expected to become Albion's new manager and he takes over with the club two points above the relegation zone and winless in their last 13 games in all competitions.
Pardew has previously managed Newcastle, Palace, West Ham and Charlton in the top flight.
John Carver, who was Pardew's assistant at Newcastle, will also move to The Hawthorns as part of the backroom team.
