Romal Palmer has joined Turkish second tier side Goztepe on a four-year contract after turning down Barnsley's offer of an extension.
The 23-year-old midfielder spent eight years at Oakwell, playing 77 games.
His first full season in senior football saw him help the Reds into the Championship play-offs as an ever-present.
Palmer struggled for form last season in a very young midfield and admitted he lost confidence as the Reds were relegated to League One.
