Crystal Palace have decided against handing new deals to strikers Emmanuel Adebayor and Marouane Chamakh and defender Brede Hangeland, the Premier League club said on its website on Monday.
Adebayor joined Palace on a short-term deal in January but netted just once in his 15 appearances for the club.
Chamakh too failed to nail down a starting spot during his two years at Selhurst Park and was not help by injuries, which restricted the Morocco international to just 66 appearances.
The London club also decided to cut ties with long-serving defender Paddy McCarthy, who made 151 appearances since arriving back in 2008.
Staying for another season, however, are goalkeeper Julian Speroni and defender Damien Delaney who both signed one-year contract extensions.
