West Ham are set to release Jonathan Calleri, Gokhan Tore and Alvaro Arbeloa this summer.
Calleri joined the Hammers in a loan move from Deportivo Maldonado last summer, but he could manage just one goal in 19 appearances in all competitions.
Tore will also return to his parent club Besiktas after making just eight appearances during the season-long loan.
Arbeloa joined the Londoners on a one-year deal last summer, but his time in with the Hammers was hit by injury problems, and he made just four appearances for Slaven Bilic's side.
