Sam Allardyce has been confirmed as the new manager of West Ham.
Owners David Sullivan and David Gold have turned to the former Bolton, Newcastle and Blackburn boss to guide them to promotion back to the Barclays Premier League at the first attempt.
The 56-year-old replaces Avram Grant, who was axed minutes after West Ham's relegation was sealed by a 3-2 defeat at Wigan a week before the end of the season. "It's a fantastic club with a great tradition and loyal supporters," said Allardyce.
"I am determined to get this club back up."
Allardyce, who has been out of work since his surprise sacking by Blackburn's new owners in December, has reportedly been offered a huge bonus if the Hammers are promoted next term.
The appointment will not be met with much enthusiasm with many West Ham fans turned off by his direct style of play. But Sullivan and Gold have opted for pragmatism over sentiment with Allardyce having taken Bolton from the Championship into Europe during his spell at the Reebok Stadium.
Allardyce added on the club's official website, www.whufc.com: "I wouldn't have taken this job if I didn't think we could bounce straight back into the Premier League.
"More than that, I wouldn't have contemplated the job if I didn't think there was the opportunity to build something substantial at West Ham.
"I know there will be West Ham fans asking whether I'm going to abandon the style of play that's been the club's heritage over the years.
"All I'll say is it will be a tale of home and away. At Upton Park we'll try to play the kind of game the fans want. We will aim to continue in the same way on our travels but we'll also be tough, hard to beat and utterly resilient."
