West Ham have appointed Avram Grant as their new manager on a four-year contract.
Grant led Portsmouth to last month's FA Cup final before leaving Fratton Park two weeks ago and also steered Chelsea into the 2008 Champions League final.
"I'm proud and honoured to be the manager of West Ham. It's an exciting challenge and I'm ready to do my best," Grant told the club's official website, www.whufc.com.
"This is a fantastic club with great fans and a history that is respected around the world. I am already looking forward to getting to work with my players in July and preparing for the new season."
Hammers co-chairman David Sullivan added; "I am delighted to welcome Avram to West Ham and am confident he will prove a success. We have taken our time over this appointment and are certain we have got the right man."
