Avram Grant has been confirmed as the new manager of West Ham United on a four-year contract.
Grant was widely expected to take the reins at Upton Park after standing down as Portsmouth manager on May 20.
The Israeli coach led a beleaguered south coast club to the FA Cup final last season and was the only candidate interviewed for the job by joint chairmen David Sullivan and David Gold.
"I am proud and honoured to be the manager of West Ham. It will be an exciting challenge and I am ready to do my best," the former Chelsea manager told the club's official website.
"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."
The Hammers parted company with Gianfranco Zola last month after he had guided them away from the Premier League's relegation zone and Sullivan is confident that he has appointed the right man to revitalise the east London club.
He explained:"We have taken our time over this appointment and are certain we have got the right man.
"We are all looking forward to next season with new players coming in and Avram's arrival is just the latest reason for real optimism."
