Former Portsmouth loanee Frederic Piquionne has joined West Ham United for an undisclosed fee from French giants Lyon, penning a three-year contract with the Irons.
The 31-year-old impressed while at Fratton Park last season, scoring 11 goals in 45 appearances, helping Pompey reach the FA Cup final despite their financial meltdown.
However, following the South Coast club's relegation to the Championship, Piquionne has opted for a move to Upton Park to join former Portsmouth boss Avram Grant.
Piquionne told his new club's official website:"I'm very happy to sign for West Ham because my last manager was Avram.
"I know Avram and I like working with him and I think he likes me. I'm coming to work hard for the squad and I hope we have a good season.
"Avram is a very, very good coach. Last year we had many problems at Portsmouth but we got to the FA Cup final. He's a very good manager.
"The ambition here has to be to reach the top ten and maybe to win the League Cup or the FA Cup. I played at Wembley last season and I scored there and it is an amazing experience I would like to have again.
"I am looking forward to performing for West Ham now and I hope to score many goals for the club."
