West Ham striking duo Ilan and Mido are to leave the club, but Luis Boa Morte is set to stay on.
The Hammers announced which players are staying and going following the release of the retained list on Tuesday, ahead of the imminent appointment of their new boss.
While it is no surprise Mido will be moving on after failing to score in nine appearances since his loan switch from Middlesbrough in January, Brazilian Ilan did make an impact, netting four times in 11 games, including crucial goals against Everton, Sunderland and Wigan as the Hammers just stayed up.
In other departures from the club, fellow striker Guillermo Franco had already revealed he will be released by West Ham when his contract expires in June, while Bondz N'Gala has joined Plymouth Argyle permanently.
Midfielder Josh Payne is also leaving, Davide Ferrari's loan from Brescia Calcio has expired and young trio Peter Loveday, Nicky Barrett and Conor Okus have all been released.
But midfielder Luis Boa Morte, whose existing deal expires on 30th June, has been offered a new deal following his successful comeback from a long-term knee injury.
Youngsters Anthony Edgar, Jordan Spence, Matthew Fry and Oliver Lee have also been offered new deals, while first professional contracts have been offered to left-back Jordan Brown, centre-back Callum McNaughton and forward Cristian Montano.
