John Carew heads a list of six players who will leave West Ham in the summer following the club's promotion back to the Premier League, reports BBC Sport. Norway striker Carew had spells in the top flight with Aston Villa and Stoke before joining West Ham in August.
However the 32-year-old struggled for games at Upton Park and the club have decided not to offer him a new deal.
Also leaving the Hammers are Julien Faubert, Abdoulaye Faye, Papa Bouba Diop, Frank Nouble and Olly Lee.
